Davis Associates, Inc. Consultants - Petroleum and Natural Gas 1717 St. James Place, Suite 460 Houston, Texas 77056 (713) 622-8955 December 15, 2006 The Trustees of North European Oil Royalty Trust P. O. Box 456 Red Bank, New Jersey 07701 Gentlemen: In accordance with your request, we have performed the calculations necessary to derive the cost depletion percentage for the 2006 calendar year. The calculation of the cost depletion percentage required that we prepare a report of the estimated remaining proved producing reserves attributable to the overriding royalty interest of North European Oil Royalty Trust (the "Trust") in the Northwest German Basin of the Federal Republic of Germany as of October 1, 2006. The proved producing reserves are as of October 1, 2006 and the reported sales are for the twelve month period ending September 30, 2006. The use of the period ending September 30, 2006 is consistent with prior years and allows the timely calculation of the royalty reserves and the cost depletion percentage for the calendar year. Based on the results of our calculation of the estimated remaining proved producing reserves contained in the first part of this report, we have performed the calculations necessary to derive the cost depletion percentage for the 2006 calendar year. As detailed in Attachment B, the cost depletion percentage for the 2006 calendar year for Trust unit owners is equal to 9.0126% of their cost basis as of January 1, 2006. DESCRIPTION OF HOLDINGS ----------------------- The Trust holds various overriding royalty rights on sales of gas, sulfur and oil from certain concessions and leases in the Federal Republic of Germany. The Oldenburg concession (1,398,000 acres), covering virtually the entire former State of Oldenburg and located in the State of Lower Saxony, is held by Oldenburgische Erdolgesellschaft ("OEG"). OEG in turn is owned equally by Mobil Erdgas-Erdol GmbH ("Mobil Erdgas"), the German subsidiary of ExxonMobil Corp. and by BEB Erdgas und Erdol GmbH ("BEB"), a joint venture of ExxonMobil Corp. and the Royal Dutch/Shell Group of Companies. As a result by direct and indirect ownership, ExxonMobil Corp. owns two-thirds of OEG and the Royal Dutch/Shell Group owns one-third of OEG. - 51 - North European Oil Royalty Trust December 15, 2006 Page 2 The Oldenburg concession is the major source of royalty income for the Trust. Although the Trust has interests in other producing areas, reserves and net sales for these areas are no longer used in the calculation of the annual cost depletion percentage. While the Trust continues to receive royalty payments from one of these interests, these royalties represent less than one (1) percent of the Trust's total royalties and the expenses involved in the determination of reserve estimates for these interests are not warranted by the royalties received. The exclusion of these reserves does not have a material effect on the calculation of the cost depletion percentage. We will continue to monitor the quarterly statements and if increases are noted that could materially add reserves to the Trust, we will resume estimating future reserves. 1. In 2002 Mobil Erdgas and BEB formed a new company ExxonMobil Production Deutschland GmbH (?EMPG?) to carry out all exploration, drilling and production within the Oldenburg concession. All sales activities are still handled by either Mobil Erdgas or BEB. (a) Under one series of rights covering the western part of the Oldenburg concession (approximately 662,000 acres), the Trust receives a royalty payment of 4% on gross receipts from sales by Mobil Erdgas of gas well gas, oil well gas, crude oil and condensate. Under the royalty agreement with Mobil Erdgas there is no deduction of costs prior to the calculation of royalties from gas well gas or oil well gas, which together account for approximately 99% of all the royalties under said agreement. (b) Under another series of rights covering the entire Oldenburg concession and pursuant to an agreement with OEG (the "OEG Agreement"), the Trust receives royalties at the rate of 0.6667% on gross receipts from sales of gas well gas, oil well gas, crude oil, condensate and sulfur (removed during the processing of sour gas) less a certain allowed deduction of costs. Under the agreement previously reached with OEG, 50% of the field handling, treatment and transportation costs as reported for state royalty purposes are deducted from gross sales receipts prior to the calculation of the royalty to be paid to the Trust. (c) The Trust also entitled to receive from Mobil Erdgas a 2% royalty payment on gross receipts of sales of sulfur obtained as a by-product of sour gas produced from the western part of Oldenburg. The payment of the sulfur royalty is provisional on whether Mobil Erdgas' selling price meets or exceeds an escalated base price. Throughout fiscal 2006, Mobil Erdgas' selling price was below the escalated base price. We will continue to monitor this situation, but until the point that Mobil Erdgas' selling meets or exceeds the escalated base price, reserves subject to this royalty will not be included in overall reserve calculations. - 52 - North European Oil Royalty Trust December 15, 2006 Page 3 OLDENBURG AREA - SALES AND RESERVES ------------------------------------ The Trust's royalty income comes primarily from the Oldenburg area. Gas production accounts for the majority of the income; however, the hydrogen sulfide in much of the gas produced necessitates its removal before the gas can be sold. At the Grossenkneten desulfurization plant, the hydrogen sulfide in sour gas is removed. Following earlier renovations and improvements to the plant, the plant's input capacity stands at 679.4 million cubic feet per day ("MMcf per day"). A second desulfurization plant NEAG remains connected by pipeline with the transportation system of the Oldenburg concession but is currently being utilized only to a limited degree for the processing of gas from Oldenburg. TOTAL SALES ----------- During the twelve months ending September 30, 2006 total sales for the Oldenburg area were as follows: WEST EAST TOTAL ---- ---- ----- Gas Well Gas-MMcf 73,500 104,605 178,105 Oil Well Gas-MMcf 53 18 71 Oil & Condensate-Barrels 112,352 64,458 176,810 Sulfur-Short Tons 295,766 646,176 941,942 GROSS RESERVES -------------- Estimated gross remaining proved producing reserves attributable to the total Oldenburg area are as follows: WEST EAST TOTAL ---- ---- ----- Gas Well Gas-MMcf 656,780 1,668,093 2,324,873 Oil Well Gas-MMcf 83 62 145 Oil & Condensate-Barrels 1,510,145 726,774 2,236,919 Sulfur-Short Tons 2,436,886 9,762,786 12,199,672 - 53 - North European Oil Royalty Trust December 15, 2006 Page 4 NET RESERVES ------------ To present an accurate picture of estimated proved producing reserves net to the Trust, the gross reserve figures outlined above must be modified by the impact of the different royalty rates in effect in the Oldenburg concession. A comparison of the Trust's overriding royalty rates in both the western and eastern areas of Oldenburg is as follows: Mobil Erdgas West East --------------- ---------- ---------- Gas & Oil 4% 0% Sulfur 2%* 0% BEB --------------- Gas & Oil 0.6667%** 0.6667%** Sulfur 0.6667%** 0.6667%** *Temporarily suspended. (See prior explanation.) **Prior to the calculation of royalties, 50% of costs as reported for state royalty purposes are deducted. The application of these royalty rates to the estimated gross remaining proved producing reserves attributable to the western and eastern Oldenburg areas yields the combined estimated proved producing reserves net to the Trust. The Trust's estimated remaining net proved producing reserves as of October 1, 2006 and net sales for the twelve month period ending September 30, 2006 are as follows: Reserves Sales -------- ----- Gas Well Gas-MMcf 40,483 4,031 Oil Well Gas-MMcf 4 2 Oil & Condensate-Barrels 74,828 5,653 Sulfur-Short Tons 66,808*** 5,158*** *** Note: At current price levels no royalties are being paid under the Mobil Erdgas sulfur royalty. A summary of net proved producing reserves by product and a five year history of net sales attributable to the royalty interests of the Trust are presented in Attachment A. - 54 - North European Oil Royalty Trust December 15, 2006 Page 5 LIMITATIONS OF AVAILABLE DATA ----------------------------- The reserves considered in this report are defined as proved producing reserves. Proved producing reserves are limited to those quantities which can be expected to be recoverable commercially from known reservoirs at current prices and costs, under existing regulatory practices and with existing conventional equipment and operating methods. Proved producing reserves do not include either proved developed non-producing reserves or any class of probable reserves. The reserve estimates were prepared using engineering methods generally accepted by the petroleum industry. The reliability of any reserve estimate is a function of the quality of available information and of engineering interpretation and judgment. The Trust, as an overriding royalty interest owner, does not receive proprietary data from the various operators on producing wells. Data, such as logs, core analysis, reservoir tests, pressure tests, gas analyses, geologic maps, and individual well production histories, which are used in volumetric and material balance type reserve estimates, are not available to the Trust. The Trust receives various monthly and quarterly statements from the operators that report production, sales and revenue data. Utilizing the same procedures as in prior years, this information plus published information received from W.E.G. (a German organization comparable to the American Petroleum Institute or the American Gas Association) has been used to prepare this annual report. In addition, the Trust retains a part-time consultant in Germany who is familiar with the German petroleum industry in general and the operating companies in particular. His periodic reports and communications are considered in the preparation of this report. We believe that reserve estimates prepared using all the available data are appropriate for use in the calculation of the cost depletion percentage. However, due to the limitations of available data, this estimate of reserves cannot have the same degree of accuracy that an estimate of reserves prepared using all pertinent data would have. Our experience in the evaluation of reserves using such limited data, including fifteen (15) years of experience working for the Trust, compensates somewhat for the limitations of available data. The data in the reports received by the Trust is in metric tons and cubic meters. The following Metric to English Unit conversion factors were used: Gas: 37.25 cubic feet per cubic meter at 14.7 psia and 60 degrees Fahrenheit Oil: 7.23 barrels per metric ton Sulfur: 1.1 short tons per metric ton - 55 - North European Oil Royalty Trust December 15, 2006 Page 6 CALCULATION OF COST DEPLETION PERCENTAGE ---------------------------------------- The categories of proved producing reserves considered in the calculation of the cost depletion percentage are oil, oil well gas, and gas well gas. Sulphur is a by-product of gas production and is not considered in the computation of total cost depletion percentage. For each category of reserves, a product base was established for the Trust as of January 1, 1976. Through the use of these product bases, we can account for the relative size of each of these categories of reserves and the corresponding impact on the calculation of the cost depletion percentage. The product base for each category of proved producing reserves is reduced annually by an adjustment that is calculated by multiplying the product base at the beginning of the current year by the depletion factor for that category of reserves. The depletion factor for each category of reserves is the ratio of the relevant net sales during the current year to the corresponding adjusted net proved producing reserves at the beginning of the current year. Significant items in the cost depletion percentage calculation that appear on Attachment B as specific item numbers, shown in parentheses, and their sources are as follows: The adjusted estimated net proved producing reserves as of 10/1/05 Line (3) is obtained by adding the estimated remaining net proved producing reserves as of 10/1/05 Line (1) and the adjustments to reserves during the period Line (2). Therefore Line (3) = Line (1) + Line (2). The depletion factor Line (6) for each category of proved producing reserves is obtained by dividing the relevant net sales Line (4) by the corresponding adjusted estimated net proved producing reserves as of 10/1/05 Line (3). Therefore Line (6) = Line (4) / Line (3). The product base for each category of proved producing reserves as of 1/1/05 Line (7) and the adjustment taken during 2005 Line (8) were obtained from the previous year's report. The product base as of 1/1/06 Line (9) forms the initial starting point for the calculation of the cost depletion percentage for the 2006 tax year. The product base for 1/1/06 Line (9) then is Line (7) - Line (8). The adjustment to the product base for each category of proved producing reserves Line (10) is used to reduce the product base as of the beginning of each year. This adjustment is the product of the depletion factor for each category of proved producing reserves Line (6) multiplied by the corresponding product base as of 1/1/06 Line (9). Therefore Line (10) = Line (6) x Line (9). - 56 - North European Oil Royalty Trust December 15, 2006 Page 7 The cost depletion percentage Line (11) then is the sum of the adjustment to the product base of each category of proved producing reserves [Sum Line (10)] divided by the sum of the product base for each category as of 1/1/05 [Sum Line (9)]. Therefore Line (11) = [Sum Line (10)] / [Sum Line (9)]. The cost depletion percentage represents the total allowable cost depletion for the 2006 calendar year for the Trust's unit owners, expressed as a percentage of their cost base as of January 1, 2006.
