PART I

ITEM 1. BUSINESS

Introduction

Reef Global Energy VIII, L.P. (the Partnership) is the third in a series of four Nevada limited partnerships comprising a program called Reef Global Energy Ventures II (the Program). The Partnership was formed in the state of Nevada on August 14, 2006. The Partnership purchased working interests in oil and gas prospects and participated in the drilling of wells on those prospects. The primary objectives of the Partnership are to generate revenue from the production of crude oil and natural gas, distribute cash to the partners, and provide tax benefits. Reef Oil & Gas Partners, L.P. (Reef) is the managing general partner of the Partnership.

The Partnership was formed to drill, complete and own working interests in oil and gas wells located onshore in the continental United States. The Partnership purchased working interests in three developmental prospects located onshore in Texas, New Mexico, and Louisiana upon which it participated in the drilling of eighteen developmental wells. The Partnership purchased working interests in three exploratory prospects located onshore in Texas and Louisiana (two prospects) upon which it participated in the drilling of three exploratory wells. In 2008, the Partnership completed drilling operations with the capital raised by the Partnership. The Partnership will not purchase additional prospects. In accordance with the Partnership’s limited partnership agreement (the Partnership Agreement), the Partnership may conduct additional drilling operations to fully develop those prospects already owned by the Partnership.

Other partnerships formed as a part of the Program also own working interests in some of the prospects owned by this Partnership. Reef also purchased working interests in certain partnership prospects for some of the other partnerships it manages. In instances where the percentage ownership of the Partnership and Reef-affiliated entities in a prospect is large enough, Reef Exploration, L.P. (RELP), an affiliate of Reef, serves as operator of the prospect. RELP originally served as operator of two developmental Partnership prospects.

In this Annual Report on Form 10-K (Annual Report), we use the term “successful” to refer to wells that are drilled, tested, and either capable of or actually producing in commercial quantities. We use the term “unsuccessful” to refer to wells that do not meet one or more of these criteria.

Acquisition and Drilling of Undeveloped Prospects

The Partnership purchased working interests in two developmental prospects internally sourced by RELP, and one developmental and three exploratory prospects generated by third parties. A “prospect” is generally defined as a contiguous oil and gas leasehold estate, or lesser interest in a leasehold estate, upon which drilling operations may be conducted. A prospect may be characterized as “exploratory” or “developmental” based upon the type of well to be drilled on the prospect. A developmental well is a well drilled within a proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be productive. Generally an exploratory well is any well that is not a developmental well, including wells drilled to find and produce oil or gas in an unproven area, wells drilled to find a new reservoir in a field previously found to be productive of oil or gas, or wells drilled to extend a known reservoir.

Prospects were evaluated utilizing data generated by RELP or provided by unaffiliated third parties to RELP. This data included well logs, production records from other area wells, seismic, geological and geophysical information, and such other information available and considered useful. Prospects in which the Partnership purchased a working interest were evaluated by petroleum engineers, geophysicists, geologists, and other technical consultants employed by or retained by RELP on the Partnership’s behalf.

The Partnership prospects were acquired pursuant to an arrangement in which the Partnership purchased part of the working interest. A working interest bears a specified portion of the costs of development, operation and maintenance. A working interest is subject to landowners’ royalty interests and may be subject to other royalty interests payable to unaffiliated third parties. Where the Partnership acquired less than 100% of the working interest, costs were reduced proportionately. The Partnership Agreement prohibits Reef or any of its affiliates from retaining any overriding royalty interest, that is, any royalty interest that would be paid out of the Partnership’s working

Table of Contents

interest, in any working interest purchased by the Partnership. The Partnership is a non-operator working interest owner in all prospects purchased by the Partnership.

Drilling and Completion Phase of Operations

On all prospects operated by RELP, drilling operations were contracted to independent third party drillers, and the costs of the wells to the Partnership were determined by actual third party costs, plus monthly operator fees charged at the competitive rate for the geographical area where the wells are located.

The Partnership generally pays drilling and completion costs as incurred. Wells drilled that fail to result in the discovery of commercial quantities of crude oil or natural gas are plugged and abandoned in accordance with applicable regulations. The Partnership participated in the drilling of seventeen successful and one unsuccessful developmental wells, and one successful and two unsuccessful exploratory wells on six prospects. As of December 31, 2012, the successful exploratory well has been plugged and abandoned. Eight successful Cole Ranch wells were sold during 2011. One of the successful developmental wells was converted to an active salt water disposal well during 2010. Of the remaining eight successful developmental wells, five are productive and three are shut-in at December 31, 2012.

Operations on one of the developmental prospects operated by RELP have ceased as a result of the sale of the eight successful Cole Ranch wells. RELP is currently the operator of eight successful developmental wells on the Sand Dunes developmental prospect in Eddy County, New Mexico. As a well operator, RELP receives operator fees during the drilling and production phase of each well at the competitive rate in the geographical area where the well is located. These fees are charged as a monthly fee per well as agreed to in an operating agreement signed by the Partnership and participating third parties in the well. The wells are subject to a model form operating agreement issued by the American Association of Petroleum Landmen and an accounting procedure for joint operations issued by the Council of Petroleum Accountants Societies of North America. The Partnership also has a working interest in one successful developmental well on one non-operated developmental prospect.

Production Phase of Operations

Wells capable of producing quantities of crude oil and/or natural gas in commercial quantities were completed by installing all surface equipment necessary to control the flow of production or to shut down the well, and by installing any storage facilities, gathering lines, or sales lines required to produce and sell the crude oil and/or natural gas production from the well. The Partnership participated in the drilling of seventeen successful developmental wells and one successful exploratory well. As of December 31, 2012, the Partnership has working interests in eight wells operated by RELP and one well operated by a third party.

On August 24, 2011, the Partnership completed the sale of certain assets in accordance with a Purchase and Sale Agreement among the Partnership, Reef Exploration, L.P., Reef Global Energy VII, L.P., and Reef Global Energy IX, L.P., affiliates of the Partnership, as sellers, and with Energen Resources Corporation (“Energen”) as buyer. This agreement included the sale of all rights, title, and interest in leases, lands, and wells located in Glasscock County, Texas (“Cole Ranch Properties”) for an aggregate purchase price to the selling parties of $10,000,000, subject to certain purchase price adjustments. The Partnership received approximately $4,438,400 of the purchase price, prior to purchase price adjustments. The Cole Ranch Properties were assigned directly to Energen at closing pursuant to an Assignment, Conveyance and Bill of Sale whereby Energen received all economic interests in the Cole Ranch Properties as if those properties had been transferred to Energen on July 1, 2011. Prior to the sale, RELP had served as the operator of the eight successful developmental wells located on the Cole Ranch Properties.

The Partnership has entered into agreements with third party marketers to sell the crude oil and/or natural gas produced from successful wells on a competitive basis at the best available terms and prices. In some cases the Partnership has elected to sell its production under marketing arrangements entered into by the operator of the well. Generally, purchase contracts for the sale of crude oil are cancelable on 30 days’ notice, but purchase contracts for the sale of natural gas may have a longer term. The Partnership sells natural gas discovered by it at negotiated prices domestically, based upon a number of factors, such as the quality of the gas, well pressure, estimated reserves, prevailing supply conditions and any applicable price regulations promulgated by the Federal Energy Regulatory Commission (FERC).

Table of Contents

Historically, the oil and gas market has experienced significant price fluctuations. Prices are impacted by local weather, supply in the area, availability and price of competitive fuels, seasonal variations in local demand, limited transportation capacity to other regions, and the worldwide supply and demand balance for crude oil.

The Partnership has not and does not expect to engage in commodity futures trading or hedging activities or to enter into derivative financial instrument transactions for trading or other speculative purposes. Accordingly, the Partnership is at risk for the volatility in commodity prices inherent in the oil and gas industry, and the level of commodity prices has a significant impact on the Partnership’s results of operations. See “Item 7A. Quantitative and Qualitative Disclosure About Market Risk.”

The Partnership’s share of revenue from productive wells is burdened by and/or subject to royalties and overriding royalties, monthly operating charges, and other operating costs. These items of expenditure involve amounts payable solely out of, or expenses incurred solely by reason of, production operations. The Partnership deducts operating expenses from the production revenue for the corresponding period.

Major Customers

The Partnership sells crude oil and natural gas on credit terms to refiners, pipelines, marketers, and other users of petroleum commodities. Revenues are received directly from these parties or, in certain circumstances, paid to the operator of the property who disburses to the Partnership its percentage share of the revenues. During the year ended December 31, 2012, one operator accounted for 94.1% of the Partnership’s crude oil and natural gas revenues. During the year ended December 31, 2011, one marketer and one operator accounted for 29.4% and 68.3% of the Partnership’s crude oil and natural gas revenues, respectively. During the year ended December 31, 2010, one marketer and one operator accounted for 44.7% and 54.7% of the Partnership’s crude oil and natural gas revenues, respectively. Due to the competitive nature of the market for purchase of crude oil and natural gas, the Partnership does not believe that the loss of any particular purchaser would have a material adverse impact on the Partnership.

Insurance

The Partnership is a named insured under blowout, pollution, public liability and workmen’s compensation insurance policies obtained by RELP. Such insurance, however, may not be sufficient to cover all liabilities. Each unit held by general partners represents a joint and several liability for unforeseen events including, without limitation, blowouts, lost circulation, and stuck drill pipe that may result in unanticipated additional liability materially in excess of a general partner’s initial investment in the Partnership.

The Partnership is a named insured under various insurance policies and intends to maintain such policies subject to its analysis of their premium costs, coverage and other factors. In the exercise of Reef ‘s fiduciary duty as managing general partner, Reef has obtained insurance on behalf of the Partnership to provide the Partnership with such coverage as Reef believes is sufficient to protect the investor partners against the foreseeable risks of drilling and production. Reef reviewed the Partnership insurance coverage prior to commencing drilling operations and periodically evaluates the sufficiency of insurance. In no event will the Partnership maintain public liability insurance of less than two times the Partnership’s capitalization. Subject to the foregoing, Reef may, in its sole discretion, increase or decrease the policy limits and types of insurance from time to time as Reef deems appropriate under the circumstances, which may vary materially.

In accordance with the Partnership Agreement of the Partnership, all general partner units held by investors were converted into limited partner units during the third quarter of 2008. At that time, Reef amended the Certificate of Limited Partnership to effectuate the conversion of the interest of the former non-Reef general partners to that of a limited partner. Non-Reef general partners have limited liability as a limited partner for any Partnership operations conducted after their conversion date. However, non-Reef general partners that converted to limited partners continue to have unlimited liability regarding partnership activities that occurred prior to their conversion date.

Competition

There are thousands of oil and gas companies in the United States. Competition is strong among persons and entities involved in the exploration for and production of crude oil and natural gas. Reef expects the Partnership to

Table of Contents

encounter strong competition at every phase of business. The Partnership competes with entities having financial resources and staffs substantially larger than those available to it.

The national supply of natural gas is widely diversified, with no one entity controlling over 5% of the supply. As a result of deregulation of the natural gas industry enacted by Congress and FERC, natural gas prices are generally determined by competitive market forces. Prices of crude oil, condensate and natural gas liquids are not currently regulated and are generally determined by competitive market forces.

Markets

The marketing of crude oil and natural gas produced by the Partnership is affected by a number of factors that are beyond the Partnership’s control and whose exact effect cannot be accurately predicted. These factors include:

· the amount of crude oil and natural gas imports;

· the availability, proximity and cost of adequate pipeline and other transportation facilities;

· the success of efforts to market competitive fuels, such as coal and nuclear energy and the growth and/or success of alternative energy sources such as wind and solar power;

· the effect of United States and state regulation of production, refining, transportation and sales;

· other matters affecting the availability of a ready market, such as fluctuating supply and demand; and

· general economic conditions in the United States and around the world.

The supply and demand balance of crude oil and natural gas in world markets has caused significant variations in the prices of these products over recent years. The North American Free Trade Agreement eliminated trade and investment barriers between the United States, Canada, and Mexico, resulting in increased foreign competition for domestic natural gas production. New pipeline projects recently approved by, or presently pending before, FERC, as well as nondiscriminatory access requirements could further substantially increase the availability of gas imports to certain U.S. markets. Such imports could have an adverse effect on both the price and volume of natural gas sales from Partnership wells.

Members of the Organization of Petroleum Exporting Countries (OPEC) establish prices and production quotas for petroleum products from time to time with the intent of affecting the global supply of crude oil and reducing, increasing or maintaining certain price levels. Reef is unable to predict what effect, if any, such actions will have on the amount of or the prices received for crude oil produced and sold from the Partnership’s wells.

In several initiatives, FERC has required pipelines to develop electronic communication and to provide standardized access via the Internet to information concerning capacity and prices on a nationwide basis, so as to create a national market. Parallel developments toward an electronic marketplace for electric power, mandated by FERC, are serving to create multi-national markets for energy products generally. These systems will allow rapid consummation of natural gas transactions. Although this system may initially lower prices due to increased competition, it is anticipated to expand natural gas markets and to improve their reliability.

Regulation

The Partnership’s operations will be affected from time to time in varying degrees by domestic and foreign political developments and by federal and state laws and regulations.

Regulation of Oil & Gas Activities. In most areas of operations within the United States the production of crude oil and natural gas is regulated by state agencies that set allowable rates of production and otherwise control the conduct of oil and gas operations. Operators of oil and gas properties are required to have a number of permits to operate such properties, including operator permits and permits to dispose of salt water. RELP possesses all material requisite permits required by the states and other local authorities in areas where it operates properties. States also control production through regulations that establish the spacing of wells or limit the number of days in a given month a well can produce. In addition, under federal law, operators of oil and gas properties are required to possess certain certificates and permits such as hazardous materials certificates, which RELP has obtained.

Environmental Matters. The Partnership’s drilling and production operations are also subject to environmental protection regulations established by federal, state, and local agencies that may necessitate significant capital outlays

Table of Contents

that, in turn, would materially affect the financial position and business operations of the Partnership. These regulations, enacted to protect against waste, conserve natural resources and prevent pollution, could necessitate spending funds on environmental protection measures, rather than on drilling operations. If any penalties or prohibitions were imposed on the Partnership for violating such regulations, the Partnership’s operations could be adversely affected.

Climate Change Legislation and Greenhouse Gas Regulation. Studies in recent years have indicated that emissions of certain gases may be contributing to warming of the Earth’s atmosphere. Many nations have agreed to limit emissions of greenhouse gases (GHGs) pursuant to the United Nations Framework Convention on Climate Change, and the Kyoto Protocol. Methane, a primary component of natural gas, and carbon dioxide, a byproduct of the burning of crude oil, natural gas, and refined petroleum products, are considered GHGs regulated by the Kyoto Protocol. Although the United States is currently not participating in the Kyoto Protocol, several states have adopted legislation and regulations to reduce emissions of GHGs. Restrictions on emissions of methane or carbon dioxide that may be imposed in various states could adversely affect our operations and demand for crude oil and natural gas. On December 7, 2009, the Environmental Protection Agency (EPA) issued a finding that serves as the foundation under the Clean Air Act to issue rules that would result in federal GHGs regulations and emissions limits under the Clean Air Act, even without Congressional action. On September 29, 2009, the EPA also issued a GHG monitoring and reporting rule that requires certain parties, including participants in the oil and gas industry, to monitor and report their GHG emissions, including methane and carbon dioxide, to the EPA. The emissions will be published on a register to be made available on the Internet. These regulations may apply to our operations. The EPA has proposed two other rules that would regulate GHGs, one of which would regulate GHGs from stationary sources, and may affect the oil and gas exploration and production industry and the pipeline industry. The EPA’s finding, the GHG reporting rule, and the proposed rules to regulate the emissions of GHGs would result in federal regulation of carbon dioxide emissions and other GHGs, and may affect the outcome of other climate change lawsuits pending in United States federal courts in a manner unfavorable to the oil and gas industry.

Natural Gas Transportation and Pricing. FERC regulates the rates for interstate transportation of natural gas as well as the terms for access to natural gas pipeline capacity. Pursuant to the Wellhead Decontrol Act of 1989, however, FERC may not regulate the price of natural gas. Such deregulated natural gas production may be sold at market prices determined by supply and demand, Btu content, pressure, location of wells, and other factors. Reef anticipates that all of the natural gas produced by the Partnership’s wells will be considered price-decontrolled natural gas and that the Partnership’s natural gas will be sold at fair market value. However, while sales by producers of natural gas can currently be made at unregulated market prices, Congress could reenact price controls in the future.

Proposed Regulation. Various legislative proposals are being considered in Congress and in the legislatures of various states, which, if enacted, may significantly and adversely affect the petroleum and gas industries. Such proposals involve, among other things, the imposition of price controls on all categories of natural gas production, the imposition of land use controls, such as prohibiting drilling activities on certain federal and state lands in protected areas, as well as other measures. At the present time, it is impossible to predict what proposals, if any, will actually be enacted by Congress or the various state legislatures and what effect, if any, such proposals will have on the Partnership’s operations.

Employees

The Partnership has no employees, and is managed by its managing general partner, Reef. RELP employs a staff including geologists, petroleum engineers, landmen, and accounting personnel who administer all of the Partnership’s operations. The Partnership reimburses RELP for technical and administrative services at cost. See “Item 11- Executive Compensation.”

ITEM 1A. RISK FACTORS

Our business activities are subject to certain risks and hazards, including the risks discussed below. If any of these events should occur, it could materially and adversely affect our business, financial condition, cash flow, or results of operations. The risks below are not the only risks we face. We may experience additional risks and uncertainties not currently known to us or, as a result of developments occurring in the future, conditions that we currently deem to be immaterial may also materially and adversely affect our business, financial condition, cash flow, and results of operations. Consequently, you should not consider this list to be a complete statement of all of our potential risks or uncertainties.

The Partnership does not intend, and is not expected, to continue as a going concern.

The original business plan for the Partnership was to use its initial capital to purchase working interests in oil and gas prospects, participate in the drilling of oil and gas wells on those prospects, retain ownership of successful wells until they were either sold or ceased operations, and distribute all operating cash flows and sales proceeds to the investor partners. It was not expected that operating revenues would be reinvested in the business other than such funds as would be necessary to maintain operation of the original wells drilled by the Partnership.

During 2011, the Partnership sold its interest in the Cole Ranch Properties (eight productive wells). As a result of this sale, the Partnership has one significant producing property that is expected to account for over 90% of future Partnership revenues. This remaining property has an estimated economic reserve life of 11 months utilizing current prices, costs, and projected production volumes at December 31, 2012. The Partnership distributed the Cole Ranch sales proceeds to investors, and has no plans to drill additional wells. The Partnership also has no plans to engage in commodity futures trading or hedging activities. Finally, the estimated economic reserve life of Partnership wells is computed based upon operating revenues and costs and does not consider Partnership general and administrative costs. Future cash flows generated from Partnership wells will be significantly impacted by actual prices received subsequent to December 31, 2012, and by actual production volumes from the Partnership’s most significant well. Current projections indicate that subsequent to December 31, 2012, revenues generated from crude oil and natural gas sales will not be sufficient to cover operating expenses and general and administrative costs. Reef, as the Partnership’s managing general partner and sole general partner, may be required to provide additional capital contributions to the Partnership should working capital and future cash generated from crude oil and natural gas sales not be sufficient to plug and abandon all Partnership wells at the end of their economic lives and pay for

Table of Contents

general and administrative costs. Our independent registered public accounting firm’s opinion on our 2012 financial statements includes an explanatory paragraph indicating substantial doubt about our ability to continue as a going concern.

Crude oil and natural gas prices are volatile, and fluctuate due to a number of factors outside of our control.

The financial condition, results of operations, and the carrying value of our oil and gas properties depend primarily upon the prices received for our crude oil and natural gas production. Crude oil and natural gas prices historically have been volatile and likely will continue to be volatile given current geopolitical conditions. Cash flow from operations is highly dependent upon the sales prices received from crude oil and natural gas production. The prices for oil and natural gas are subject to a variety of factors beyond our control. These factors include:

· the domestic and foreign supply of crude oil and natural gas; consumer demand for crude oil and natural gas, and market expectations regarding supply and demand;

· the ability of the members of OPEC to agree to and maintain crude oil price and production controls;

· domestic government regulations and taxes;

· the price and availability of foreign exports and alternative fuel sources;

· weather conditions, including hurricanes and tropical storms in and around the Gulf of Mexico;

· political conditions in crude oil and natural gas producing regions, including the Middle East, Nigeria, and Venezuela; and

· domestic and worldwide economic conditions.

These factors and the volatility of the energy markets make it extremely difficult to predict price movements. Also, crude oil and natural gas prices do not necessarily move in tandem. Declines in crude oil and natural gas prices would not only reduce revenues and cash flow available for distributions to partners, but could reduce the amount of oil and natural gas that can be economically produced from successful wells drilled by the Partnership, and, therefore, have an adverse effect upon financial condition, results of operations, crude oil and natural gas reserves, and the carrying value of the Partnership’s oil and gas properties. Approximately 35.2% of the Partnership’s estimated proved reserves were crude oil reserves and 64.8% were natural gas reserves at December 31, 2012. As a result, the Partnership’s financial results are sensitive to fluctuations in both crude oil and natural gas prices.

The Partnership, while not prohibited from engaging in commodity trading or hedging activities in an effort to reduce exposure to short-term fluctuations in the price of crude oil and natural gas, has not engaged in such activities. Accordingly, the Partnership is at risk for the volatility in crude oil and natural gas prices, and the level of commodity prices has a significant impact upon the Partnership’s results of operations.

A global economic downturn could have a material adverse impact on our financial position, results of operations and cash flows.

The oil and gas industry is cyclical and tends to reflect general economic conditions. The United States and other countries around the world experienced an economic downturn in 2008 and 2009 which had an adverse impact on demand and pricing for crude oil and natural gas. Another downturn similar to that experienced in 2008 and 2009 could lead to a similar negative impact on crude oil and natural gas prices as a result of reduced demand for crude oil and natural gas that. This would likely have a significant impact on the Partnership’s operating cash flows and profitability. Declines in crude oil and natural gas prices may also impact the value of our crude oil and natural gas reserves, which could result in future impairment charges to reduce the carrying value of the Partnership’s oil and gas properties.

We are subject to substantial operating risks that may adversely affect the results of operations.

There are numerous hazards involved in the drilling and operation of oil and gas wells, including blowouts involving possible damages to property and third parties, bodily injuries, mechanical failures, explosions, uncontrollable flows of crude oil, natural gas or well fluids, fires, formations with abnormal pressure, pollution, releases of toxic gas and other environmental hazards and risks. The Partnership could suffer substantial losses as a result of any of these risks. The Partnership is not fully insured against all risks inherent to the oil and gas business. Uninsured liabilities would reduce the funds available to the Partnership, may result in the loss of Partnership properties and may create liability for the general partners. Although the Partnership maintains insurance coverage in amounts Reef deems

Table of Contents

appropriate, it is possible that insurance coverage may be insufficient. In that case Partnership assets may have to be sold to pay personal injury and property claims and the cost of controlling blowouts or replacing damaged equipment rather than for drilling activities.

We cannot control activities on non-operated properties.

The Partnership could be held liable for the joint interest obligations of other working interest owners, such as nonpayment of costs and liabilities arising from the actions of other working interest owners.

Crude oil and natural gas reserve data are estimates based upon assumptions that may be inaccurate and existing economic and operating conditions that may differ from future economic and operating conditions.

Securities and Exchange Commission (SEC) rules require the Partnership to present annual estimates of reserves. Reservoir engineering is a subjective process of estimating the recovery from underground accumulations of crude oil and natural gas that cannot be precisely measured, and is based upon assumptions that may vary considerably from actual results. Accordingly, reserve estimates may be subject to upward or downward adjustments. Actual production, revenues and expenditures with respect to reserves will likely vary from estimates, and such variances could be material.

You should not assume the present value of future net cash flows referred to in this Annual Report to be the current market value of our estimated crude oil and natural gas reserves. The estimated discounted future net cash flows from our proved reserves as of December 31, 2012 are based upon the 12-month unweighted arithmetic average of the first-day-of-the-month prices and costs in effect when the estimate is made. Actual current prices, as well as future prices and costs, may be materially higher or lower. Further, actual future net cash flows will be affected by factors such as the amount and timing of actual production, supply and demand for crude oil and natural gas, and changes in governmental regulations and tax rates.

The Partnership Agreement limits Reef’s liability to each partner and the Partnership and requires the Partnership to indemnify Reef against certain losses.

Reef will have no liability to the Partnership or to any partner for any loss suffered by the Partnership, and will be indemnified by the Partnership against loss sustained by it in connection with the Partnership if:

· Reef determines in good faith that its action was in the best interest of the Partnership;

· Reef was acting on behalf of or performing services for the Partnership; and

· Reef’s actions did not constitute negligence or misconduct.

The production and producing life of Partnership wells is uncertain.

Production will decline. It is not possible to predict the life and production of any well. The actual life could differ from that which is anticipated. Sufficient crude oil or natural gas may not be produced for a partner to receive a profit or even to recover his initial investment. In addition, production from the Partnership’s oil and gas wells, if any, will decline over time, and does not indicate any consistent level of future production. This production decline may be rapid and irregular when compared to a well’s initial production.

Extreme weather conditions may adversely affect production operations and partner distributions.

The Partnership’s most significant producing property is located in the coastal region of Louisiana. This area is susceptible to extreme weather conditions, especially those associated with hurricanes. In the event of a hurricane and related storm activity, such as windstorms, storm surges, floods and tornados, Partnership operations in the region may be adversely affected. The occurrence of a hurricane or other extreme weather may harm or delay the Partnership’s operations or distribution of revenues, if any.

Our dependence on third parties for the processing and transportation of crude oil and natural gas may adversely affect the Partnership’s revenues and, consequently, the distribution of net cash flows to investor partners.

We rely on third parties to process and transport the crude oil and natural gas produced by the Partnership’s successful wells. In the event a third party upon whom we rely is unable to provide transportation or processing services, and another third party is unavailable to provide such services, the Partnership may have to temporarily shut-in successful wells, and revenues to the Partnership and distributions to investor partners related to those wells may be delayed.

We face strong competition within the energy industry.

The oil and gas industry is highly competitive. Competition is encountered in all aspects of Partnership operations, including the requisition of service contractors. Many of our competitors are larger, well-established companies with substantially larger operating staffs and greater capital resources than those of the Partnership, Reef and its affiliates. We may not be able to conduct our operations successfully, obtain service contractors, consummate transactions, and obtain technical, managerial and other professional personnel in this highly competitive environment. Specifically, larger competitors may be able to pay more for competent personnel than the Partnership, Reef and its affiliates. In addition, such competitors may be able to expend greater resources on the existing and changing technologies that will be increasingly important to success. Such competitors may also be in a better position to secure oilfield services, as well as equipment, more timely or on more favorable terms. Finally, oil and gas producers are increasingly facing competition from providers of non-fossil energy, and government policy may favor those competitors in the future.

The Partnership has limited external sources of funds, which could result in a shortage of working capital.

The Partnership only has nominal funds available for Partnership purposes unless there are revenues from Partnership operations. Any future requirement for additional funding for development, operations, and asset retirements will have to come from the Partnership’s current working capital or future revenues. Reef cannot assure the partners that Partnership operations will be sufficient to provide the Partnership with necessary additional funding. Reef, as the Partnership’s managing general partner and sole general partner, may be required to provide additional capital contributions to the Partnership should working capital and future cash generated from crude oil and natural gas sales not be sufficient to plug and abandon all Partnership wells at the end of their economic lives and pay for general and administrative costs.

The Partnership may incur liabilities for liens against its subcontractors.

Although Reef will try to determine the financial condition of nonaffiliated subcontractors, if subcontractors fail to timely pay for materials and services, the properties of the Partnership could be subject to materialmen’s and workmen’s liens. In that event, the Partnership could incur excess costs in discharging such liens.

Drilling Activities and Productive Wells

The Partnership purchased working interests in prospects located onshore in Louisiana, Texas, and New Mexico. The Partnership purchased working interests in three developmental prospects. The Partnership participated in drilling eight successful developmental wells on the Cole Ranch prospect in Glasscock County, Texas, one successful and one unsuccessful developmental well on a prospect located in Terrebonne Parish, Louisiana, and eight successful developmental wells on the Sand Dunes prospect located in Eddy County, New Mexico.

Table of Contents

The Partnership purchased working interests in three exploratory prospects upon which three exploratory wells were drilled. The Partnership participated in drilling one successful exploratory well located in Lavaca County, Texas. The Partnership participated in drilling two unsuccessful exploratory wells located in St. Mary and Iberville Parish, Louisiana.

On August 24, 2011, the Partnership completed the sale of certain assets in accordance with a Purchase and Sale Agreement among the Partnership, Reef Exploration, L.P., Reef Global Energy VII, L.P., and Reef Global Energy IX, L.P., affiliates of the Partnership, as sellers, and with Energen as buyer. This agreement included the sale of the Cole Ranch Properties for an aggregate purchase price to the selling parties of $10,000,000, subject to certain purchase price adjustments. The Partnership received approximately $4,438,400 of the purchase price, prior to purchase price adjustments. The Cole Ranch Properties were assigned directly to Energen at closing pursuant to an Assignment, Conveyance and Bill of Sale whereby Energen received all economic interests in the Cole Ranch Properties as if those properties had been transferred to Energen on July 1, 2011. Prior to the sale, RELP had served as the operator of the eight successful developmental wells located on the Cole Ranch Properties. Net proceeds received by the Partnership related to this sale were distributed to the partners in 2011.

The successful exploratory well was plugged and abandoned and one of the successful developmental wells was converted to an active salt water disposal well during 2010. Eight successful Cole Ranch wells were sold during 2011. Of the remaining eight successful developmental wells, five are productive and three are shut-in as of December 31, 2012.

Proved Crude Oil and Natural Gas Reserves

Estimates of the Partnership’s proved reserves are prepared and presented in accordance with SEC rules and accounting standards which require SEC reporting entities to prepare their reserve estimates using pricing based upon the un-weighted arithmetic average of the first-day-of-the-month commodity prices over the preceding 12-month period and current costs. All of the Partnership’s reserves are located in the United States.

The estimated net proved crude oil and natural gas reserves at December 31, 2012, 2011, and 2010 are summarized below. The estimated quantities of proved crude oil and natural gas reserves discussed in this section include only the amounts which the Partnership reasonably expects to recover in the future from known oil and gas reservoirs under the current economic and operating conditions. Proved reserves include only quantities that the Partnership expects to recover commercially using current prices, costs, existing regulatory practices, and technology. Therefore, any changes in future prices, costs, regulations, technology or other unforeseen factors could materially increase or decrease the proved reserve estimates.

	Oil (BBL)	Gas (MCF)
Net proved reserves as of December 31, 2010	46,860	209,170
Net proved reserves as of December 31, 2011	6,470	85,660
Net proved reserves as of December 31, 2012	560	6,180

The standardized measure of discounted future net cash flows as of December 31, 2012, 2011, and 2010 is computed by applying the 12-month average beginning-of-month price for the year, costs, and legislated tax rates and a discount factor of 10% to net proved reserves. The standardized measure of discounted future net cash flows does not purport to present the fair value of our crude oil and natural gas reserves.

Standardized measure of discounted future net cash flows as of December 31, 2010	$	1,996,240
Standardized measure of discounted future net cash flows as of December 31, 2011	$	639,320
Standardized measure of discounted future net cash flows as of December 31, 2012	$	21,840

During the year ended December 31, 2012, the Partnership recorded property impairment costs of proved properties totaling $82,616 as a result of the net capitalized costs of proved oil and gas properties exceeding the sum of estimated future net revenues from proved reserves, using the methodologies described above. During the years ended December 31, 2011 and 2010, the Partnership recorded no property impairment costs of proved properties.

Qualifications of Technical Persons and Internal Controls Over the Reserves Estimation Process

The Partnership used an independent petroleum consulting company, Forrest A. Garb & Associates, Inc., (“FGA”) of Dallas, Texas, to prepare its December 31, 2012, 2011, and 2010 estimates of net proved crude oil and natural gas reserves. FGA estimated reserves for all of our properties as of December 31, 2012, 2011, and 2010. The technical personnel responsible for preparing the reserve estimates at FGA meet the requirements regarding qualifications, independence, objectivity, and confidentiality set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. FGA is an independent firm of petroleum engineers and geologists. They do not own an interest in any of our properties, and are not employed on a contingent fee basis. FGA’s report was developed utilizing state reporting records and published production data purchased from third parties, and data provided by Reef. Their reserve summary, which contains further discussions of the reserve estimates and evaluations, as well as the qualifications of FGA’s technical personnel responsible for overseeing their estimates and evaluations, is included as Exhibit 99.1 to this Annual Report.

Reef’s policies and practices regarding internal controls over the recording of reserves are structured to objectively and accurately estimate oil and gas reserve quantities and present values in compliance with SEC regulations and US Generally Accepted Accounting Principles (“GAAP”).

Reef maintains a staff of technical personnel who are well versed in the engineering evaluation computer programs and technology used and who provide well and production data to our independent petroleum engineering firm, FGA. Our accounting department accumulates historical production and pricing data and lease operating expenses for our wells, as well as the percentage interest owned by the Partnership, which is reviewed by our technical staff. Reserve estimates are prepared by FGA. Our technical staff and members of our accounting department meet regularly with FGA’s representatives to review properties and discuss methods and assumptions used in the preparation of their estimates. Mr. Jerald Sluder, Senior Reservoir Engineer for RELP, is primarily responsible for overseeing the preparation of reserve estimates by FGA. Mr. Sluder has a B.S. in Petroleum Engineering, is a Registered Professional Engineer in the State of Texas and has over eighteen years of industry experience in oil and gas operations. Mr. Sluder is an active member of the Society of Petroleum Engineers and of the Petroleum Engineers Club of Dallas. Any significant reserve changes are approved by Mr. Daniel C. Sibley, Chief Financial Officer and General Counsel of RELP, and Mr. Michael J. Mauceli, Chief Executive Officer of RELP.

Title to Properties

The Partnership’s interests in producing and non-producing acreage are in the form of assigned direct interests in leases held by the Partnership or by Reef on behalf of the Partnership. Such properties are subject to customary royalty interests and could be subject to liens incident to operating agreements, liens for current taxes and overriding royalty interests and other burdens. The Partnership believes that none of these burdens will materially interfere with the use of such properties in the operation of the Partnership’s business and that it has or will obtain satisfactory title to all of its leases. Title will be held by the Partnership or by Reef on behalf of the Partnership.

ITEM 3. LEGAL PROCEEDINGS

The Partnership is not, and has not been, a party to any legal proceedings.

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

As of December 31, 2012, the Partnership had one managing general partner, and 536 non-Reef investor partners (“investor partners”). Reef holds a total of 32.425 general partner units and the investor partners hold 616.076 limited partner units. No established trading market exists for the units.

Cash which, in the sole judgment of the managing general partner, is not required to meet the Partnership’s obligations is available for distribution to the partners in accordance with the Partnership Agreement. The Partnership has made cash distributions to the partners of interest income and crude oil and natural gas sales revenues, less operating and general and administrative costs since April 2007. Cash distributions are distributed 15.45% to the managing general partner (based upon the 11% interest not represented by units and the 4.45% interest represented by Partnership units) and 84.55% to investor partners. The Partnership’s most recent cash distribution to investor partners occurred in July 2012. However, current projections indicate that no funds will be available for future distribution to investor partners unless the Partnership has available cash after settling all remaining obligations of the Partnership, including asset retirement and general and administrative costs.

Investor limited partner interests are transferable, subject to certain restrictions contained in the Partnership Agreement; however, no assignee of a unit in the Partnership can become a substituted partner without the written consent of both the transferor and Reef.

The Partnership has adopted a unit repurchase program. Under the terms of the program, the managing general partner is obligated to purchase up to 5% of the units in the Partnership per year during the period set forth in the Partnership Agreement unless changes in oil and gas pricing meet certain criteria specified in the prospectus supplement, dated July 14, 2006. However, the managing general partner’s obligation to purchase units is limited to $500,000 per year in the aggregate for all partnerships previously or subsequently organized by the managing general partner or its affiliates. The Partnership did not repurchase any units in 2012.

Table of Contents

The estimate of proved crude oil and natural gas reserves used to determine property impairment expense, and also utilized in the Partnership’s disclosures of supplemental information regarding oil and gas producing activities, including the standardized measure of discounted cash flows, was prepared by an independent petroleum engineer at December 31, 2012, 2011, and 2010, utilizing prices and costs as promulgated by the SEC. Reservoir engineering is a subjective and inexact process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner, and is based upon assumptions that may vary considerably from actual results. Accordingly, reserve estimates may be subject to upward or downward adjustments. Actual production, revenues and expenditures with respect to reserves will likely vary from estimates, and such variances could be material.

Asset retirement costs and liabilities associated with future site restoration and abandonment of long-lived assets are initially measured at fair value which approximates the cost a third party would incur in performing the tasks necessary to retire such assets. The fair value is recognized in the financial statements as the present value of expected future cash expenditures for site restoration and abandonment. Subsequent to the initial measurement, the effect of the passage of time on the liability for the net asset retirement obligation (accretion expense) and the amortization of the asset retirement cost are recognized in the results of operations.

The following table summarizes the Partnership’s asset retirement obligation for the years ended December 31, 2012 and 2011.

	2012			2011
Beginning asset retirement obligation	$	75,090		$	269,161
Accretion expense	12,181			10,955
Retirement related to sale of proved properties	—			(205,026		)
Retirement related to property abandonment and restoration	(2,797		)	—
Ending asset retirement obligation	$	84,474		$	75,090

The portion of the Partnership’s asset retirement obligation associated with properties having estimated remaining economic lives of less than twelve months is classified as a current liability on the accompanying balance sheet.

Recognition of Revenue

The Partnership has entered into sales contracts for disposition of its share of crude oil and natural gas production from productive wells. Revenue is recognized based upon the metered volumes delivered to those purchasers each month. Any significant over or under balanced gas positions are disclosed in the financial statements. As of December 31, 2012, 2011, and 2010, the Partnership had no material gas imbalance positions.

Overview

Reef Global Energy VIII, L.P. is a Nevada limited partnership formed to acquire, explore, develop, and produce crude oil, natural gas, and natural gas liquids for the benefit of its investor partners. The Partnership’s primary purposes are to generate revenues from the production of crude oil and natural gas, distribute cash flow to investors, and provide tax benefits to investors. The majority of the Partnership’s proceeds were used to purchase working interests in prospects and drill oil and gas wells upon those prospects.

The Partnership raised capital from the sale of Partnership units to investor partners and Reef and used those funds for the purchase of working interests in prospects and for drilling and completion operations and administrative costs during its drilling phase of operations. The Partnership did not borrow funds during the drilling phase of operations, and interest income and crude oil and natural gas revenues from successful wells, net of operating and general and administrative costs, are distributed to the partners. The Partnership is allowed to borrow funds in accordance with the Partnership Agreement, or utilize cash flows from successful wells in order to conduct further development upon prospects initially purchased by and drilled on by the Partnership during the drilling phase of operations. The Partnership completed its drilling phase of operations during the first quarter of 2008. The Partnership currently has no plans to drill additional wells on any Partnership prospect, or to acquire additional prospects.

Table of Contents

The Partnership does not operate in any other industry segment. During the drilling and completion phase of operations, the Partnership expended approximately $599,000 for the purchase of working interests in three developmental prospects, and expended approximately $368,000 for the purchase of working interests in three exploratory prospects. The Partnership purchased working interests in three prospects in Louisiana, two in Texas, and one in New Mexico, all of which are located onshore. The Partnership participated in drilling eighteen developmental and three exploratory wells on these prospects during 2007 and 2008. The Partnership participated in drilling seventeen successful developmental wells and one unsuccessful development well. The Partnership participated in drilling one successful exploratory well and two unsuccessful exploratory wells.

The Partnership is permitted but is not expected to engage in commodity futures trading or hedging activities, and therefore is subject to commodity price risk. See “Item 7A - Quantitative And Qualitative Disclosure About Market Risk.”

Liquidity and Capital Resources

The Partnership was funded with initial capital contributions totaling $16,090,928. Investor partners purchased 520.793 general partner units and 95.283 limited partner units for $15,401,896. Reef purchased 32.425 general partner units, or 5% of the total units sold, for $689,032. Reef also contributed $131,210 in connection with its obligation to pay 1% of all leasehold, drilling, and completion costs. Organization and offering costs totaled $2,310,285, leaving capital contributions of $13,911,853 available for Partnership activities. The Partnership was formed on August 14, 2006 and the last partner was admitted to the Partnership on December 29, 2006.

The Partnership did not borrow additional funds in accordance with limitations set forth in the Partnership Agreement during the drilling phase of operations. The Partnership expended $14,102,150 on the drilling of 21 wells and $53,048 on general and administrative expenses during its initial drilling phase of operations. Expenditures in excess of available capital contributions were deducted from Partnership distributions.

Please see Item 1A of this Annual Report for a list of risk factors that could impact the Partnership. The Partnership distributes to investors the net cash flow from interest income and crude oil and natural gas sales revenues from successful wells, less operating and general and administrative costs.

The Partnership had working capital of $41,461 at December 31, 2012. Subsequent to expending the initial available Partnership capital contributions on prospect acquisitions and drilling and completion costs of partnership wells, the Partnership’s working capital consists primarily of cash flows from productive properties, which have been utilized to pay cash distributions to investors. Current projections indicate that no funds will be available for future distribution to investor partners unless the Partnership has available cash after settling all remaining obligations of the Partnership, including asset retirement and general and administrative costs.

Results of Operations

Year ended December 31, 2012 compared to Year ended December 31, 2011

During the year ended December 31, 2012, the Partnership incurred a net loss of $148,866, compared to net income of $4,697,482 for the year ended December 31, 2011. Excluding the gain on sale related to the Cole Ranch properties described below, the Partnership had net income totaling $407,265 during the year ended December 31, 2011. The decrease in net income between these comparative periods is the result of the loss of the Cole Ranch property oil and gas production, declines in production volumes from the Partnership’s most significant remaining well and in oil and gas sales prices, and property impairment cost.

On August 24, 2011, the Partnership completed the sale of the Cole Ranch properties to Energen, effective July 1, 2011. The Partnership recognized a gain related to this transaction of $4,290,217 during the year ended December 31, 2011.

Table of Contents

Partnership crude oil and natural gas production volumes are declining due to natural production declines from existing Partnership wells, the fact that the Partnership has not drilled any new productive wells since 2008 and has no plans to conduct additional drilling activity, and the sale of eight producing wells on the Cole Ranch properties during the third quarter of 2011. The Cole Ranch properties accounted for 28.4% and 15.9% of crude oil and natural gas sales volumes, respectively, during the year ended December 31, 2011 and accounted for 29.3% of the Partnership’s sales revenues during the year ended December 31, 2011. There are no sales volumes or revenues from the Cole Ranch properties included in the results of operations for the year ended December 31, 2012.

The Rob L. RA SUA CL&F #1 (‘Gumbo II”) well, located in Terrebonne Parish, Louisiana is the most productive well in which the Partnership has an interest. Beginning in August 2011, as water volumes associated with the production of the crude oil and natural gas from the Gumbo II well began to increase, the actual production volumes of crude oil and natural gas from the well began to decrease. During the year ended December 31, 2011, the Partnership share of production volumes from the Gumbo II well was 6,705 barrels of crude oil and 34,478 Mcf of natural gas, or 69.3% and 82.9% of Partnership production volumes for the period. During the year ended December 31, 2012, the Partnership share of production volumes from the Gumbo II well was 2,527 barrels of crude oil and 13,461 Mcf of natural gas, or 94.1% and 98.1% of Partnership production volumes for the period, a volume drop of approximately 61.7% on an equivalent barrel of oil (“EBO”) basis. Production from existing Partnership wells will continue to decline in future quarters, and combined with the loss of all production from the Cole Ranch properties the Partnership previously sold, will lead to continuing declines in sales volumes in future periods. The economic life of the Partnership is dependent upon the lives of the most significant wells in which it participates. The current remaining estimated economic reserve life of the Gumbo II well is estimated to be approximately 11 months using prices prepared in accordance with SEC rules and accounting standards and current costs.

The sales price for crude oil decreased by 9.3%, to an average price of $82.64 per Bbl for the year ended December 31, 2012, compared to an average price of $91.16 for the year ended December 31, 2011, and the sales price for natural gas decreased by 45.9%, to an average price of $2.62 per Mcf for the year ended December 31, 2012, compared to an average price of $4.84 per Mcf for the year ended December 31, 2011.

The combined effect of the loss of production from the Cole ranch properties, decreased volumes from the Partnership’s most significant well, and decreased prices caused total sales revenues to decrease by $825,881, or 76.2%, on a comparative period-to-period basis. The Partnership has not and is currently not engaged in commodity futures trading, hedging activities, or derivative financial instrument transactions for trading or other speculative purposes. The Partnership sells a vast majority of its production from successful oil and gas wells on a month-to-month basis at current spot market prices. Accordingly, the Partnership is at risk for the volatility in commodity prices inherent in the oil and gas industry, and the level of commodity prices has a significant impact on the Partnership’s results of operations. At current production volume levels, which are expected to continue to decline in future periods, projections indicate that subsequent to December 31, 2012, revenues generated from crude oil and natural gas sales will not be sufficient to cover operating expenses and general and administrative costs.

Lease operating expenses decreased from $236,380 during the year ended December 31, 2011 to $69,363 during the year ended December 31, 2012, primarily due to the sale of the Partnership’s interest in the Cole Ranch properties. The Cole Ranch properties accounted for $132,031 of the $236,380 in lease operating expenses incurred during the year ended December 31, 2011. Production taxes decreased from $82,869 during the year ended December 31, 2011 to $19,296 during the year ended December 31, 2012, due primarily to the decline in sales revenues.

The Partnership incurred $105,530 of depletion, depreciation, and amortization expense and $82,616 of property impairment expense during the year ended December 31, 2012 compared to $149,772 of depletion, depreciation, and amortization expense and no property impairment expense during the year ended December 31, 2011. The decrease in depletion, depreciation, and amortization expense is due to the reduced depletable basis of the Partnership resulting primarily from the sale of the Cole Ranch properties during the third quarter of 2011. The impairment expense incurred during the year ended December 31, 2012 was the result of the reduction in the economic reserve life of the Gumbo II well, which reduced the Partnership’s economic recoverable reserves.

General and administrative costs decreased from $196,633 incurred during the year ended December 31, 2011 to $118,140 incurred during the year ended December 31, 2012, primarily due to decreased overhead charges from RELP. The allocation of RELP’s overhead to the Partnership is a large portion of general and administrative

Table of Contents

expenses, and is based upon several factors, including the level of drilling activity, revenues, and capital and operating expenditures of each partnership managed by Reef compared to the total levels of all such partnerships. The administrative overhead charge to the Partnership decreased from $92,156 for the year ended December 31, 2011 to $20,468 for the year ended December 31, 2012.

Year ended December 31, 2011 compared to Year ended December 31, 2010

During the year ended December 31, 2011, the Partnership had net income of $4,697,482, compared to net income of $490,699 for the year ended December 31, 2010. Gain on the sale of the Cole Ranch Properties was the primary cause of the increase in net income. Excluding this gain, net income for the year ended December 31, 2011 was $407,265 compared to $490,699 for the year ended December 31, 2010.

On August 24, 2011, the Partnership completed the sale of the Cole Ranch Properties to Energen, effective July 1, 2011. The Partnership recognized a gain related to this transaction of $4,290,217 during the year ended December 31, 2011. Although the Partnership follows the full cost method of accounting, due to the significance of the sale and its effect on the rate of depletion and amortization the Partnership recognized a gain related to this transaction. In addition, revenues and lease operating expenses for these properties decreased during the last half of 2011 due to the sale.

Partnership oil and gas sales volumes are declining due to natural production declines from existing Partnership wells, the sale of the eight Cole Ranch wells during the third quarter of 2011, and the fact that the Partnership is not drilling and has no plans to conduct additional drilling activity. During the year ended December 31, 2011, the Partnership’s share of sales volumes from the Gumbo II well accounted for 6,705 Bbl and 34,478 Mcf, or 69.3% and 82.9% of the Partnership’s crude oil and natural gas sales volumes, respectively. During the year ended December 31, 2010, the Gumbo II well accounted for 7,187 Bbl and 38,552 Mcf, or 55.5% and 73.1% of the Partnership’s crude oil and natural gas sales volumes, respectively. After the sale of the Cole Ranch wells, the Gumbo II well is expected to account for over 90% of both crude oil and natural gas sales in future quarters. In addition, sales volumes from the eight Cole Ranch wells declined by almost 8,000 Mcf due to the sale of the Partnership’s interests in these wells as of August 24, 2011. The eight Cole Ranch wells provided approximately 35.4% of the Partnership’s oil volumes and 25.2% of the Partnership’s gas volumes during the first half of 2011. This decline was partially offset by the return of seven Sand Dunes wells to production during the third and fourth quarters of 2010. Beginning in November 2011, production volumes from the Gumbo II well began declining as a result of increasing water production from the well. The economic life of the Partnership is dependent upon the lives of the most significant wells in which it participates. At December 31, 2011, the estimated reserve life of the Gumbo II well was estimated to be approximately 5.83 years using then current prices and costs.

Sales prices for crude oil rose by 26.1%, to an average price of $91.16 for the year ended December 31, 2011, compared to an average price of $72.27 for the year ended December 31, 2010. Sales prices for natural gas declined by 6.6% to an average price of $4.84 per Mcf for the year ended December 31, 2011, compared to an average price of $5.18 per MCF for the year ended December 31, 2010. As a result of the decreased sales volumes, lower gas prices, and the sale of the Cole Ranch wells, total sales revenues decreased by approximately $125,297 for the year ended December 31, 2011. The Partnership has not and is currently not engaged in commodity futures trading, hedging activities, or derivative financial instrument transactions for trading or other speculative purposes. The Partnership sells a vast majority of its production from successful oil and gas wells on a month-to-month basis at current spot market prices. Accordingly, the Partnership is at risk for the volatility in commodity prices inherent in the oil and gas industry, and the level of commodity prices has a significant impact on the Partnership’s results of operations.

Lease operating costs increased from $225,960 during the year ended December 31, 2010 to $236,380 during the year ended December 31, 2011. Marketing and gathering and legal expenses on the Gumbo II well increased over the comparative periods. In addition, operating costs increased as a result of returning seven Sand Dunes wells to production during the third and fourth quarters of 2010, following the conversion of one of the Sand Dunes wells to a salt water disposal well that began disposal operations in August 2010. Several of the Sand Dunes wells required rod and tubing repairs during 2011, leading to increased workover expenses. These increases were only partially offset by decreased expenses related to the sale of the Partnership’s interest in the eight Cole Ranch wells.

Table of Contents

Production taxes increased during the year ended December 31, 2011 compared to the year ended December 31, 2010 due to a one time severance tax adjustment received from the operator of the Gumbo II well. During the second quarter of 2010, the Partnership received a large severance tax credit from the operator of the Gumbo II well, because the well obtained a severance tax exemption from the State of Louisiana for the period from inception through February 2010. This one-time tax adjustment resulted in the Partnership showing a negative amount for severance taxes during the second quarter of 2010, and skewed the production tax expense shown for the year ended December 31, 2010.

The Partnership incurred $149,772 of depletion, depreciation, and amortization expense during the year ended December 31, 2011 compared to $223,689 of depletion, depreciation, and amortization expense during the year ended December 31, 2010. This decrease is due to the reduced depletable basis of the Partnership and the combination of declining production and rising oil prices between the comparative periods, which have led to a reduced depletion rate applied to the remaining basis.

General and administrative costs decreased from $228,549 incurred during the year ended December 31, 2010 to $196,633 incurred during the year ended December 31, 2011, primarily due to decreased overhead charges from RELP. The allocation of RELP’s overhead to partnerships is the largest factor in general and administrative expenses, and is based upon several factors, including the level of drilling activity, revenues, and capital and operating expenditures of each partnership compared to the total levels of all partnerships. Primarily as a result of the sale of the Cole Ranch Properties, the Partnership’s percentage of activity compared to that of other partnerships is declining. The administrative overhead charge to the Partnership decreased from $132,371 for the year ended December 31, 2010 to $92,156 for the year ended December 31, 2011.

Off-Balance Sheet Arrangements

The Partnership does not participate in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structure finance or special purpose entities (SPEs), which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As of December 31, 2012 and 2011, the Partnership was not involved in any unconsolidated SPE transactions or any other off-balance sheet arrangements.

Contractual Obligations Table

The Partnership has no obligations under non-cancelable agreements as of December 31, 2012.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Commodity Price Risk

The Partnership has not and does not expect to engage in commodity futures trading or hedging activities or to enter into derivative financial instrument transactions for trading or other speculative purposes. The Partnership sells a vast majority of its production from successful oil and gas wells on a month-to-month basis at current spot market prices. Accordingly, the Partnership is at risk for the volatility in commodity prices inherent in the oil and gas industry, and the level of commodity prices has a significant impact on the Partnership’s results of operations.

Assuming the production levels we attained during the year ended December 31, 2012, a 10% change in the price received for our crude oil would have had an approximate $22,200 impact on our crude oil revenues, and a 10% change in the price received for our natural gas would have had an approximate $3,500 impact on our natural gas revenues.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As the managing general partner of the Partnership, Reef maintains a system of controls and procedures designed to provide reasonable assurance as to the reliability of the financial statements and other disclosures included in this Annual Report, as well as to safeguard assets from unauthorized use or disposition. The Partnership, under the supervision and with participation of its management, including the principal executive officer and principal financial and accounting officer of the Partnership’s managing general partner, Reef Oil & Gas Partners, L.P., evaluated the effectiveness of its “disclosure controls and procedures” as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of the end of the period covered by this Annual Report. Based on that evaluation, the principal executive officer and principal financial and accounting officer of our managing general partner have concluded that the Partnership’s disclosure controls and procedures are effective to ensure that information required to be disclosed by the Partnership in reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms, and includes controls and procedures designed to ensure that information required to be disclosed by us in such reports is accumulated and communicated to our management, including the principal executive officer and principal financial and accounting officer of our managing general partner, as appropriate to allow timely decisions regarding financial disclosure.

Management Report on Internal Control Over Financial Reporting

Management of the Partnership is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation under the framework in Internal Control — Integrated Framework, management of the Partnership concluded that the Partnership’s internal control over financial reporting was effective as of December 31, 2012.

This annual report does not include an attestation report of the Partnership’s independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Partnership’s registered public accounting firm pursuant to rules of the SEC that permit the Partnership to provide only management’s report in this annual report.

Changes in Internal Controls

There have not been any changes in the Partnership’s internal controls over financial reporting during the fiscal quarter ended December 31, 2012 that have materially affected, or are reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

ITEM 11. EXECUTIVE COMPENSATION

The following table summarizes the items of compensation to be received by Reef as the managing general partner from the Partnership.

Recipient	Form of Compensation	Amount
Managing General Partner	Partnership interest (excluding any partnership interest resulting from the purchase of units)	10% interest
Managing General Partner	Management fee	15% of subscriptions
Managing General Partner and its Affiliates	Direct and administrative costs	Reimbursement at cost
Affiliate of the Managing General Partner	Operator’s per-well charges	Competitive prices
Managing General Partner and its Affiliates	Payment for equipment, supplies, marketing, and other services	Cost or competitive prices

Reef’s “partnership interest,” as described in the table above, refers only to its interest as managing general partner and does not include the interest Reef has as the result of its purchase of units in the Partnership, or the 1% interest Reef has as the result of its payment of 1% of all leasehold, drilling, and completion costs. Reef purchased 5.00% of the outstanding Partnership units. Reef received a 10% interest as managing general partner of the Partnership and a 1% interest as a result of Reef’s payment of 1% of all leasehold, drilling, and completion costs, for a total of an 11% interest. This 11% interest is not represented by partnership units. Reef has a total interest in the Partnership of 15.45%.

Reef is entitled to receive a management fee equal to 15% of the Partnership subscriptions exclusive of the units purchased by Reef. From this amount Reef pays all of the Partnership’s organization and offering costs, including sales commissions. The management fee is payable to Reef in two parts. Reef initially received an amount not to exceed 13.5% to cover actual sales commissions and actual organization and offering costs. The remainder of the management fee is paid to Reef from the net cash flow available for partner distributions, at a rate not to exceed $1 million per year. The total management fee owed Reef is $2,310,285. The Partnership recorded $2,260,285 of this amount as offering costs, and $50,000 as organization costs. Of this amount, $2,085,232 has been paid to Reef to cover actual sales commissions and organization and offering costs, and $225,053 has been paid to Reef from net cash flows of the Partnership.

Reef is reimbursed for direct costs and all documented out-of-pocket expenses incurred on behalf of the Partnership, including administrative costs. During the years ended December 31, 2012, 2011, and 2010, the Partnership reimbursed Reef $0, $0, and $9,561, respectively, for technical services costs which have been capitalized as project costs, and $31,255, $107,445, and $140,628, respectively, for administrative costs included as general and administrative expenses.

Operator fees are payable to RELP for the wells on the two prospects where RELP serves as operator. RELP receives operator fees during the drilling and production phase of each well at the competitive rate in the geographical area where the well is located. These fees are charged as a monthly fee per well as agreed to in an operating agreement signed by the Partnership and participating third party working interest owners in the well. During the years ended December 31, 2012, 2011, and 2010, the Partnership paid operator fees totaling $4,842, $32,910, and $44,724 to RELP. As of December 31, 2012, RELP serves as operator for one Partnership prospect containing four productive wells, three shut-in wells, and one salt water disposal well.

Compensation Committee

Because the Partnership has no directors, it does not have a compensation committee.

The managing general partner received a 10% interest in the Partnership as compensation for forming the Partnership, and also holds a 1% interest in the Partnership as a result of paying 1% of all leasehold, drilling and completion costs. In addition to this 11% interest not represented by Partnership units, Reef purchased 5% of the 648.501 Partnership units and, therefore, holds 5% of the 89% interest in the Partnership (4.45%) held by the unit holders.

1. Organization and Basis of Presentation

Reef Global Energy VIII, L.P. (the “Partnership”) is the third in a series of four Nevada limited partnerships comprising a program called Reef Global Energy Ventures II (the “Program”), pursuant to an S-1 Registration Statement declared effective by the Securities and Exchange Commission (the “SEC”) on July 7, 2005. In order to be formed, each partnership was required to sell a minimum of 40 partnership units at $25,000 per unit, including units purchased by the managing general partner. Each partnership formed as a part of the Program offered a minimum of 1,000 and a maximum of 2,000 units for sale. The Program was authorized to sell up to 1,600 limited partner units and 6,400 general partner units during the period beginning July 8, 2005 through July 7, 2007. The Partnership offered 2,000 units for sale ($50,000,000), consisting of up to 400 limited partner units and up to 1,600 general partner units. Investor funds were held in escrow and were subject to reimbursement with interest if the minimum number of units was not sold. The Program filed a prospectus supplement with the SEC on July 14, 2006 describing the Partnership, and commenced offering units in the Partnership. Upon reaching the minimum subscription level, the Partnership was formed on August 14, 2006. The Partnership offering closed December 29, 2006, with sales to outside investors totaling 520.793 general partner units and 95.283 limited partner units, and sales to the managing general partner totaling 32.425 general partner units.

The Partnership is a Nevada limited partnership formed under the Nevada Uniform Limited Partnership Act. Reef Oil & Gas Partners, L.P. (“Reef”) serves as the Partnership’s managing general partner. Partnership interests are held by the managing general partner and investor partners who are general and limited partners (“investor partners”). The managing general partner received a 10% interest in the Partnership as compensation for forming the Partnership, and also holds a 1% interest in the Partnership as a result of paying 1% of all leasehold, drilling and completion costs. This 11% interest is not represented by Partnership units. In addition, Reef purchased 5% of the Partnership units and, therefore, holds 5% of the 89% interest in the Partnership (4.45%) held by the unit holders. The Partnership purchased working interests in exploratory and developmental drilling prospects and drilled oil and gas wells located onshore in the continental United States. Other partnerships formed as a part of this Program, as well as other partnerships managed by Reef also own interests in some of the prospects purchased by this Partnership. In instances where Reef-affiliated entities own a majority working interest in a prospect, wells drilled on that prospect may be operated by Reef Exploration, L.P. (“RELP”), an affiliate of the managing general partner. The Partnership does not operate in any other industry segment.

Upon completion of the Partnership’s drilling program in 2008, all general partner units held by investors other than the managing general partner were converted into limited partner units. The Partnership currently has 616.076 units of limited partner interest and 32.425 units of general partner units outstanding.

Under the terms of the partnership agreement, certain income and expense items are allocated differently between the managing general partner and the investor partners. Allocations of income and expense to the managing general partner and investor partners are made quarterly based upon the number and type of partnership units held at the end of the quarter.

Organization and offering costs are allocated 100% to investor partners, as the managing general partner purchases its units net of the 15% fee for organization and offering costs. Quarterly cash distributions to partners, if any, are based upon the number and type of partnership units held at the close of the prior quarter. Cash distributions to partners of the net cash flow from interest income and crude oil and natural gas sales revenues, less operating and general and administrative costs are distributed 15.45% to the managing general partner (based upon the 11% interest not represented by units and the 4.45% interest represented by Partnership units) and 84.55% to investor partners.

Going Concern

The accompanying financial statements have been prepared assuming the Partnership is a going concern, which assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business.

During 2011, the Partnership sold its interest in the Cole Ranch properties, which were comprised of eight productive wells. As a result of this sale, the Partnership has one significant producing property that is expected to account for over 90% of future Partnership revenues. The property has an estimated remaining economic reserve life of 11 months utilizing current prices, costs, and projected production volumes at December 31, 2012. The Partnership distributed the proceeds from the sale of the Cole Ranch properties to its partners, and has no plans to drill additional wells. The Partnership also has no plans to engage in commodity futures trading or hedging activities. Finally, the estimated economic reserve life of Partnership wells is computed based upon operating revenues and costs and does not consider Partnership general and administrative costs. Future cash flows generated from Partnership wells will be significantly impacted by actual prices received, and by actual production volumes from the Partnership’s most significant well. Current projections indicate that subsequent to December 31, 2012, revenues generated from crude oil and natural gas sales will not be sufficient to cover operating expenses and general and administrative costs. These factors raise substantial doubt about the ability of the Partnership to continue as a going concern. The financial statements do not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amount and classification of liabilities that might result should the Partnership be unable to continue as a going concern. The managing general partner is considering several options related to the Partnership, including the possible sale of marketable assets, as a result of these declining cash flows.

2. Summary of Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates.

Cash and Cash Equivalents

The Partnership considers all highly liquid investments with maturity dates of no more than three months from the purchase date to be cash equivalents. Cash and cash equivalents consist of demand deposits and money market investments invested with a major national bank, which at times may exceed federally insured limits. The Partnership has not experienced any losses in such accounts, and does not expect any loss from this exposure. The carrying value of the Partnership’s cash equivalents approximates fair value.

Risks and Uncertainties

The Partnership has not engaged in commodity futures trading or hedging activities and has not entered into derivative financial instrument transactions for trading or other speculative purposes. Accordingly, the Partnership is at risk for the volatility in commodity prices inherent in the oil and gas industry, and the level of commodity prices has a significant impact on the Partnership’s results of operations.

Oil and Gas Properties

The Partnership follows the full cost method of accounting for oil and gas properties. Under this method, all direct costs and certain indirect costs associated with acquisition of properties and successful as well as unsuccessful exploration and development activities are capitalized. Depreciation, depletion, and amortization of capitalized oil and natural gas properties and estimated future development costs, excluding unproved properties, are based on the

F-7

Table of Contents

Reef Global Energy VIII, L.P.

Notes to Financial Statements (continued)

unit-of-production method using estimated proved reserves, as determined by independent petroleum engineers. For these purposes, proved natural gas reserves are converted to equivalent barrels of crude oil at a rate of 6 Mcf to 1 Bbl.

In applying the full cost method, the Partnership performs a quarterly ceiling test on the capitalized costs of oil and gas properties, whereby the capitalized costs of oil and gas properties are limited to the sum of the estimated future net revenues from proved reserves using prices that are the 12-month unweighted arithmetic average of the first-day-of-the-month price for crude oil and natural gas held constant and discounted at 10%, plus the lower of cost or estimated fair value of unproved properties, if any. If capitalized costs exceed the ceiling, an impairment loss is recognized for the amount by which the capitalized costs exceed the ceiling, and is shown as a reduction of oil and gas properties and as property impairment expense on the Partnership’s statement of operations. No gain or loss is recognized upon sale or disposition of oil and gas properties, unless such a sale would significantly alter the rate of depletion and amortization. During the year ended December 31, 2012, the Partnership recognized property impairment expense of proved properties totaling $82,616. During the years ended December 31, 2011 and 2010, the Partnership recognized no property impairment expense of proved properties. During the year ended December 31, 2011, the Partnership recognized gain of $4,290,217 related to the Partnership’s sale and disposition of all rights, title, and interest in leases, lands, and wells located in Glasscock County, Texas (“Cole Ranch Properties”).

Estimates of Proved Oil and Gas Reserves

Estimates of the Partnership’s proved reserves at December 31, 2012, 2011, and 2010 are prepared and presented in accordance with SEC rules and accounting standards which require SEC reporting entities to prepare their reserve estimates using the unweighted arithmetic average of the first-day-of-the-month commodity prices over the preceding 12 month period and current costs. Future prices and costs may be materially higher or lower than these prices and costs, which would impact the estimate of reserves and future cash flows. The Partnership’s proved reserve information included in this report was based upon evaluations prepared by independent petroleum engineers.

Reserves and their relation to estimated future net cash flows impact the Partnership’s depletion and impairment calculations. As a result, adjustments to depletion and impairment are made concurrently with changes to reserve estimates. If proved reserve estimates decline, the rate at which depletion expense is recorded increases, reducing net income. A decline in estimated proved reserves and future cash flows also reduces the capitalized cost ceiling and may result in increased impairment expense.

Restoration, Removal, and Environmental Liabilities

The Partnership is subject to extensive Federal, state and local environmental laws and regulations. These laws regulate the discharge of materials into the environment and may require the Partnership to remove or mitigate the environmental effects of the disposal or release of petroleum substances at various sites. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefit are expensed.

Liabilities for expenditures of a non-capital nature are recorded when environmental assessments and/or remediation is probable, and the costs can be reasonably estimated. Such liabilities are generally undiscounted values unless the timing of cash payments for the liability or component is fixed or reliably determinable.

The Partnership has recognized an estimated liability for future plugging and abandonment costs. A liability for the estimated fair value of the future plugging and abandonment costs is recorded with a corresponding increase in the full cost pool at the time a new well is drilled or acquired. Depreciation expense associated with estimated plugging and abandonment costs is recognized in accordance with the full cost methodology.

The Partnership estimates a liability for plugging and abandonment costs based on historical experience and estimated well life. The liability is discounted using the credit-adjusted risk-free rate. Revisions to the liability could occur due to changes in well plugging and abandonment costs or well useful lives, or if federal or state regulators enact new well restoration requirements. The Partnership recognizes accretion expense in connection with the discounted liability over the remaining life of the well.

Retirement related to property abandonment and restoration	(2,797		)	—
Ending asset retirement obligation	$	84,474		$	75,090

Recognition of Revenue

The Partnership enters into sales contracts for disposition of its share of crude oil and natural gas production from productive wells. Revenues are recognized based upon the Partnership’s share of metered volumes delivered to its purchasers each month. The Partnership had no material gas imbalances at December 31, 2012, 2011 and 2010.

Income Taxes

The Partnership’s net income or loss flows directly through to its partners, who are responsible for the payment of Federal taxes on their respective share of any income or loss. Therefore, there is no provision for federal income taxes in the accompanying financial statements.

As of December 31, 2012, the tax basis of the Partnership’s assets exceeds the financial reporting basis of the assets by approximately $2.4 million, primarily due to the difference between property impairment costs deducted for financial reporting purposes and intangible drilling costs deducted for income tax purposes.

Accounting for Uncertainty in Income Taxes

The Financial Accounting Standards Board (“FASB”) provides guidance on accounting for uncertainty in income taxes. This guidance is intended to clarify the accounting for uncertainty in income taxes recognized in a company’s financial statements and prescribes the recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

Under this guidance, evaluation of a tax position is a two-step process. The first step is to determine whether it is more-likely-than-not that a tax position will be sustained upon examination, including the resolution of any related appeals or litigation based on the technical merits of that position. The second step is to measure a tax position that meets the more-likely-than-not threshold to determine the amount of benefit to be recognized in the financial statements. A tax position is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.

Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent period in which the threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not criteria should be de-recognized in the first subsequent reporting period in which the threshold is no longer met. Penalties and interest are classified as income tax expense.

Based on the Partnership’s assessment, there are no material uncertain tax positions as of December 31, 2012 and 2011. The Partnership is subject to examination of income tax filings in the U.S. and various state jurisdictions for the years ended December 31, 2012 and 2011. The Partnership has not been subjected to any audits by the Internal Revenue Service for these periods.

Fair Value of Financial Instruments

The estimated fair values for financial instruments have been determined at discrete points in time based on relevant market information. These estimates involve uncertainties and cannot be determined with precision. The estimated fair value of cash, accounts receivable, accounts receivable from affiliates, and accounts payable approximates their carrying value due to their short-term nature.

Comprehensive Income

Comprehensive income is defined as a change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources and includes all changes in equity during a period except those resulting from investments by owners and distributions to owners. The Partnership has no items of comprehensive income other than net income in any period presented. Therefore, net income as presented in the consolidated statements of operations equals comprehensive income.

3. Transactions with Affiliates

The Partnership has no employees. RELP employs a staff including geologists, petroleum engineers, landmen and accounting personnel who administer all of the Partnership’s operations. The Partnership reimburses RELP for technical and administrative services at cost. During the years ended December 31, 2012, 2011, and 2010, the Partnership incurred technical services and administrative costs totaling $31,255, $107,445, and $150,189, respectively. Of these amounts, $0, $0, and $9,561 represent technical services costs capitalized as project costs, and $31,255, $107,445, and $140,628 represent administrative costs included as general and administrative expenses.

RELP processes joint interest billings and revenue payments on behalf of the Partnership. At December 31, 2012 and 2011, RELP owed the Partnership $17,273 and $128,014, respectively, for net revenues processed in excess of joint interest and technical and administrative charges. The Partnership settles its balances with Reef and RELP at least on a quarterly basis.

If an affiliate of Reef serves as operator of a Partnership prospect, then operator fees are payable to the affiliate. Under such circumstances, such affiliate receives fees at the competitive rate in the geographical area where the prospect is located during the drilling and production phase of operations. These fees are charged as a monthly fee per well as agreed to in an operating agreement signed by the Partnership as well as outside third party working interest owners in the well. During the years ended December 31, 2012, 2011, and 2010, the Partnership paid operating overhead fees totaling $4,842, $32,910, and $44,724 to RELP, respectively.

5. Commitments and Contingencies

The Partnership is not currently involved in any legal proceedings.

6. Partnership Equity

Sales of Partnership units began on July 14, 2006. Proceeds received were placed into an interest bearing escrow account until the Partnership reached the minimum subscription level of 40 units. The Partnership was formed on August 14, 2006, and the sale of Partnership units was closed on December 29, 2006. The Partnership raised $15,401,896 from the sale of 616.076 Partnership units to investor partners. Reef purchased 32.425 units (5%) for $689,032. Reef also contributed $131,210 in connection with its obligation to pay 1% of all leasehold, drilling, and completion costs.

All units, except those purchased by Reef, paid a 15% management fee to Reef to pay for Partnership organization and offering costs, including sales commissions. These costs totaled $2,310,285, leaving net capital contributions of $13,911,853 available for Partnership oil and gas activities. Of the $2,310,285 management fee, offering costs were $2,260,285 and organization costs were $50,000. The Partnership participated in the drilling of twenty-one wells

and completed drilling operations with the capital raised by the Partnership in 2008.

Reef exclusively manages and controls all aspects of the business of the Partnership. The Partnership agreement prohibits participation by investor partners in the Partnership’s day-to-day business decisions.

7. Subsequent Events

During March 2013, the Partnership entered into an agreement to sell its interests in the Sand Dunes properties in Eddy County, New Mexico to a third party for approximately $8,000. The Sand Dunes properties include eight wells, of which four were producing, three were shut-in, and one had been converted into a salt water disposal well as of December 31, 2012. The Sand Dunes properties accounted for approximately 5.9% of the Partnership’s total sales revenues during the year ended December 31, 2012.

Crude Oil and Natural Gas Reserves

Net Proved Developed Reserve Summary

The reserve information presented below is based upon estimates of net proved reserves that were prepared by the independent petroleum engineering firms Forrest A. Garb & Associates, Inc., as of December 31, 2012, 2011, and 2010. A copy of the Forrest A. Garb & Associates summary reserve report is included as Exhibit 99.1 to this Annual Report. Proved crude oil and natural gas reserves are the estimated quantities of crude oil and natural gas which geological and engineering data demonstrate with reasonable certainty to be economically recoverable in future years from known reservoirs under existing economic conditions, operating methods and governmental regulations (i.e. prices and costs as of the date the estimate is made). Proved developed reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods. At December 31, 2012, all of the Partnership’s reserves are classified as proved developed reserves. All of the Partnership’s reserves are located in the United States.

The following table sets forth changes in estimated net proved developed crude oil and natural gas reserves for the years ended December 31, 2012, 2011 and 2010.

(2) BOE (barrels of oil equivalent) is calculated by converting 6 MCF of natural gas to 1 BBL of oil. A BBL (barrel) of oil is one stock tank barrel, or 42 U.S. gallons liquid volume, of crude oil or other liquid hydrocarbons.

Standardized Measure of Discounted Future Net Cash Flows

Certain information concerning the assumptions used in computing the valuation of proved reserves and their inherent limitations are discussed below. The Partnership believes such information is essential for a proper understanding and assessment of the data presented.

For the years ended December 31, 2012, 2011, and 2010, calculations were made using average prices of $94.68, $95.84, and $79.79 per barrel of crude oil, respectively, and $2.76, $4.15, and $4.39 per MCF of natural gas, respectively. Prices and costs are held constant for the life of the wells; however, prices are adjusted by well in accordance with sales contracts, energy content quality, transportation, compression and gathering fees, and regional price differentials.

These assumptions used to compute estimated future cash inflows do not necessarily reflect Reef’s expectations of the Partnership’s actual revenues or costs, nor the present worth of the properties. Further, actual future net cash flows will be affected by factors such as the amount and timing of actual production, supply and demand for crude oil and natural gas, and changes in governmental regulations and tax rates. Sales prices of both crude oil and natural gas have fluctuated significantly in recent years. Reef, as managing general partner, does not rely upon the following information in making investment and operating decisions for the Partnership.

Future development and production costs are computed by estimating the expenditures to be incurred in developing and producing the proved crude oil and natural gas reserves at the end of the year, based on year-end costs and assuming continuation of existing economic conditions.

A 10% annual discount rate is used to reflect the timing of the future net cash flows relating to proved reserves.

December 31,	2012			2011			2010
Crude oil and natural gas properties owned by the Partnership:
Future cash inflows	$	78,360		$	1,038,400		$	4,829,310
