DENVER – July 28, 2010 – Whiting Petroleum Corporation’s (NYSE: WLL) production in the second quarter of 2010 totaled a record 5.88 million barrels of oil equivalent (MMBOE), of which 4.77 MMBOE were crude oil/natural gas liquids (81%) and 1.11 MMBOE was natural gas (19%). This second quarter 2010 production total equates to a new record daily average production rate of 64,600 barrels of oil equivalent (BOE), and represents a 17% increase over the 55,309 BOE per day average rate in the second quarter of 2009. Compared to the first quarter of 2010, daily production rose 8%. The production increases in the second quarter of 2010 were primarily the result of organic production growth in Whiting’s North Dakota Bakken play.

Financial Results – Second Quarter 2010

Whiting reported second quarter 2010 net income available to common shareholders of $119.9 million, or $2.35 per basic share and $2.12 per diluted share, on total revenues of $377.6 million. This compared to a second quarter 2009 loss of $93.2 million, or $1.83 per basic and diluted share, on total revenues of $230.2 million. The fully diluted common share count of 59,225,000 used in the Company’s second quarter 2010 financial reporting assumes full conversion of the Company’s Convertible Perpetual Preferred Stock into 7,946,000 common shares.

The Company’s 2010 second quarter results include after-tax unrealized derivative gains of $46.4 million, or $0.78 per diluted share. Excluding this gain and certain other items, Whiting reported second quarter 2010 adjusted net income available to common shareholders of $72.2 million, or $1.42 per basic share and $1.31 per diluted share. This compared to a second quarter 2009 adjusted net loss available to common shareholders of $0.6 million, or $0.01 per basic and diluted share. A reconciliation of adjusted net income available to common shareholders versus net income available to common shareholders is included later in this news release.

Discretionary cash flow in the second quarter of 2010 totaled $228.2 million, up 108% from the $109.7 million reported for the same period in 2009. The increase in discretionary cash flow in the second quarter of 2010 versus the comparable 2009 period was primarily the result of a 40% increase in the Company’s realized oil price (net of hedging) as well as a 17% increase in the Company’s net production. A reconciliation of discretionary cash flow to net cash provided by operating activities is included later in this news release.

Operating and Financial Results - First Six Months 2010

Production in the first six months of 2010 totaled 11.3 MMBOE, or 62,245 BOE per day, representing a 14% increase over the 9.9 MMBOE, or 54,815 BOE per day, in the first six months of 2009.

For the six months ended June 30, 2010, Whiting reported net income available to common stockholders of $201.1 million, or $3.95 per basic share and $3.58 per diluted share, on total revenues of $728.9 million. This compared to a net loss of $136.9 million, or $2.78 per basic and diluted share, on total revenues of $394.0 million in the first six months of 2009. Excluding after-tax unrealized derivative gains and losses and certain other items, Whiting reported adjusted net income available to common shareholders of $134.7 million, or $2.64 per basic share and $2.46 per diluted share, in the first six months of 2010. This compared to an adjusted net loss available to common shareholders of $29.7 million, or $0.60 per basic and diluted share, in the comparable 2009 period.

Discretionary cash flow in the first six months of 2010 totaled $442.7 million. This total represents a 144% increase over the $181.6 million of discretionary cash flow generated in the first six months of 2009.

James J. Volker, Whiting’s Chairman, President and CEO, commented, “We are extremely pleased with our results in the second quarter and in the first half of 2010. The production performance of our Bakken play in North Dakota during 2010 has outstripped our previous well results in the area. In addition, our two EOR projects at the Postle and North Ward Estes fields continue to generate organic production growth. All three projects are heavily weighted toward oil, which currently sells at an approximate 17 to 1 ratio to the price of natural gas. Furthermore, 100% of our drilling activity and 99.5% of our proved reserves and production are located onshore in the Lower 48. Based on the performance of these projects in the second quarter of 2010, we have increased our year-over-year production growth estimate to a range of 15.0% to 17.0%, up from a previous range of 11.5% to 13.0%. While we raised our production guidance again, we have not increased our 2010 capital budget of $830 million.”

Mr. Volker continued, “Our first half discretionary cash flow of $442.7 million exceeded our $307.3 million of capital expenditures in the first half. We used a portion of the excess cash flow to pay down bank debt. At June 30, 2010, borrowings on our $1.1 billion credit facility totaled $30 million, down from $100 million at March 31, 2010 and down from $160 million at December 31, 2009. One of our primary objectives in 2010 is to establish another resource play. We believe our Lewis & Clark prospect area, where we have amassed a 223,000 net acre position, has the potential to be such a play.”

Operations Update

Core Development Areas

Bakken and Three Forks Development Increases Production

The following table summarizes the Company’s operated and non-operated net production from the Sanish and Parshall fields in the second quarter of 2010 and in June 2010:

Operated and Non-operated Net Production for Sanish and Parshall Fields (In BOE)

(1) Includes approximately 875 net BOE per day of NGLs and natural gas from plant operations.

Whiting’s net production from the Middle Bakken and Three Forks formations in the Sanish and Parshall fields of Mountrail County, North Dakota averaged 27,380 BOE per day in June 2010, up 17% from the 23,365 BOE average daily rate in March 2010 and up 77% from the 15,448 BOE average daily rate in June 2009.

Sanish Field. Whiting’s net production from the Sanish field in the second quarter of 2010 averaged 20,045 BOE per day, an increase of 86% over the second quarter 2009 average rate of 10,765 BOE per day. Our net production from the Sanish field averaged 21,775 BOE per day in June 2010, a 31% increase from 16,640 BOE per day in March 2010 and a 114% increase from 10,179 BOE per day in June 2009. Whiting plans to continue with its current nine operated drilling rig count in the Sanish field through 2012.

From April 20, 2010 through July 20, 2010, Whiting completed 21 operated wells in the Sanish field, bringing to 40 the number of Whiting-operated wells completed in 2010. The total number of Whiting-operated wells in the Sanish field now stands at 108. These 40 wells were comprised of 36 Bakken wells, 26 of which were infill wells, and four wells that were completed in the Three Forks formation. The average initial production rate for these 40 wells came to 2,478 BOE per day, which represents a 20% increase over the 2,057 BOE average initial production rate for wells completed prior to January 1, 2010.

Whiting recently completed two high-volume Bakken wells in the Sanish field. On July 17, 2010, the Fladeland 12-10H flowed at a daily rate of 4,126 barrels of oil and 1.8 million cubic feet (MMcf) of gas (4,431 BOE) during a 24-hour test of the Middle Bakken. The infill well, the second well drilled on this 1,280-acre spacing unit, was tested on a 52/64-inch choke with a flowing casing pressure of 830 pounds per square inch (psi). The well, which is located in the northwest portion of the Sanish field, was fracture stimulated in 30 stages, 22 stages using sliding sleeve technology and eight stages using the “plug and perf” method. Whiting holds a 70% working interest and a 56% net revenue interest in the Fladeland well.

The Fladeland 12-10H recorded the third highest initial production rate for a Whiting-operated Bakken well drilled to date in the Sanish field. The Maki 11-27 was tested on October 24, 2009 flowing 4,761 BOE per day, while the Richardson Federal 11-9H flowed 4,570 BOE per day during a 24-hour test on October 22, 2008. Both of these wells, which were drilled in the east-central part of the Sanish field, were the initial wells drilled in their respective 1,280-acre spacing units.

During a 24-hour test of the Middle Bakken formation on June 18, 2010, the Hansen 12-20H flowed at a daily rate of 3,863 barrels of oil and 1.7 MMcf of gas, or 4,144 BOE per day. The initial 24-hour production rate was gauged on a 40/64-inch choke with a flowing casing pressure of 1,120 psi. The well was fracture stimulated in a total of 18 stages, all using sliding sleeves. Whiting, the operator of the well, holds a 99% working interest and an 80% net revenue interest in the new producer.

As of July 20, 2010, 11 operated wells were being completed or awaiting completion and nine operated wells were being drilled in the Sanish field. In 2010, Whiting intends to drill a total of 90 operated wells and participate in a total of eight non-operated wells in the field for a total of 98 wells (52 net wells). Of the 98 total gross wells, 88 are planned Bakken wells and 10 are planned Three Forks wells. As of July 20, 2010, Whiting estimates that at least 57 Bakken wells and 128 Three Forks wells remain to be drilled in the Sanish field.

Whiting estimates that the total completed well costs for its most recently completed wells in the Sanish field will come in below $5.0 million per well. The wells that we drilled in the second quarter of 2010 reached a total measured depth of approximately 20,000 feet, including 10,000 feet of lateral, in an average of 20 days, with two wells taking 15 days from spud date to total depth. The reduction in drilling time and associated costs is primarily the result of our “Drill Wells On Paper” (DWOP) program, which applies the best practices and best logistical planning of all our drilling and completion contractors to produce drilling and completion efficiencies. Prior to the implementation of our DWOP program, it took an average of 39 days from spud date to total depth. With an average of 19 fewer days on location, we are saving approximately $900,000 per well in drilling costs.

Whiting’s 17-mile oil line connecting the Sanish field to the Enbridge pipeline in Stanley, North Dakota is currently transporting between 17,000 barrels and 21,000 barrels per day. This 8-inch diameter line has a daily capacity of approximately 65,000 barrels of oil per day. Whiting expects to have between 23,000 barrels and 25,000 barrels per day of its operated oil production in the pipeline by the end of September 2010. The Company is currently saving between $1.00 and $2.00 per barrel in transportation costs for each barrel that is being transported through its pipeline rather than being transported by truck.

Enbridge Inc. expects to add 30,000 barrels per day of take-away capacity to its pipeline in the first quarter of 2011, which will bring the pipeline’s total take-away capacity to 191,000 barrels per day. Enbridge anticipates adding an incremental 85,000 barrels per day in the second quarter of 2013 for a total of 276,000 barrels per day of take-away capacity.

Whiting’s Robinson Lake gas plant is currently processing 29.1 MMcf of gas per day (gross). Whiting expects capacity to be expanded to 45 MMcf per day in September 2010, 60 MMcf per day in January 2011 and 90 MMcf per day in July 2011. Whiting owns a 50% interest in the plant. The plant receives 25% of the net proceeds from natural gas and NGL sales in the area. As of July 20, 2010, sales from the plant were 21.3 MMcf of gas and 3,471 barrels of NGLs per day, from which Whiting was netting 2.7 MMcf of gas and 434 barrels of NGLs per day due to its plant ownership. As of July 20, 2010, there were 93 Whiting-operated wells and 86 third-party wells connected to the gas gathering system.

Parshall Field. Immediately east of the Sanish field is the Parshall field, where we own interests in 73,242 gross acres (18,188 net acres). The Company’s net production from its interests in the Parshall field during the second quarter of 2010 averaged 5,850 BOE per day, a 15% increase from the 5,085 BOE per day average in the second quarter of 2009. Our net production from the Parshall field averaged 5,605 BOE per day in June 2010, a 17% decrease from 6,725 BOE per day in March 2010 and a 6% increase from the 5,268 BOE average daily rate in June 2009. The operator of the Parshall field has drilled almost all of its Bakken locations and is currently pursuing a moderate pace of development of the Three Forks formation with a one rig program. As of July 20, 2010, we had participated in 120 wells at Parshall, of which 116 are producing, three are awaiting completion and one is being drilled.

Increasing Production from EOR Projects

Postle Field. Production continues to increase from our Postle field, which produces from the Morrow sandstone, in Texas County, Oklahoma. In the second quarter of 2010, the field produced at an average net rate of 9,550 BOE per day, representing a 22% increase from the 7,800 BOE net daily rate in the second quarter of 2009. The Postle field continued to outperform independent engineering estimates in the second quarter of 2010. As of July 20, 2010, there was one drilling rig and three workover rigs active in the field.

North Ward Estes Field. Production from our North Ward Estes field, located in Ward and Winkler Counties, Texas, averaged 7,700 BOE per day in the second quarter of 2010. This average rate represented a 22% increase from the 6,325 net daily rate in the second quarter of 2009 and a 2% sequential increase from the 7,530 net daily rate in the first quarter of 2010. Late last year, Whiting increased its planned CO2 injection volume for the field. The production response from CO2 injection in Phase 2 resulted in net production from North Ward Estes increasing 14% to 8,080 BOE per day in March 2010 from 7,110 BOE per day in December 2009. Since March 2010, Whiting has temporarily reached its CO2 injection capacity at the North Ward Estes field and has plans to install two additional compressors by mid-October 2010. Consequently, the average production rate at North Ward Estes in June 2010 was 7,655 BOE per day. Whiting is currently injecting more water in its “Water Alternating Gas” (WAG) process and expects to continue to do so until the additional compressors are installed.

At North Ward Estes, Whiting initiated Phase I of our CO2 injection project in May 2007 and Phase II began in March 2009. CO2 injection in the field during 2010 has averaged between 210 MMcf and 250 MMcf per day, of which approximately half has been recycled gas and the other half has been purchased CO2. We estimate that Phase III-A will be substantially complete in the fourth quarter of 2010.

New Prospect Drilling Areas

Lewis & Clark Prospect Area. The Lewis & Clark prospect area is located in Golden Valley, Billings and Stark Counties, North Dakota. Whiting continues to actively lease in the area and has raised its acreage position to 340,241 gross (225,685 net) acres, up from 329,339 gross (211,128 net) acres at March 31, 2010. Based on gross acres and drilling two laterals per 1,280-acre spacing unit, Whiting has up to 500 potential well locations on this acreage which could target the Three Forks formation.

Whiting anticipates drilling and completing at least 13 Three Forks wells on the prospect during 2010. Drilling operations on the first three wells began in early May 2010, and each well has reached total depth. All three wells are currently awaiting completion. The lateral length at all three wells is approximately 10,000 feet. Whiting currently plans to complete each well with a 30-stage fracture stimulation, 22 stages using sliding sleeves and eight stages using the “plug and perf” method.

On November 25, 2009, Whiting completed the Federal 32-4HBKCE flowing 1,970 BOE per day during a 24-hour test of the Three Forks formation. The well’s 7,686-foot lateral was fracture stimulated in 15 stages, all using sliding sleeve technology. The discovery well’s average daily rate during the first 30, 60 and 90 days of production was 695 BOE, 531 BOE and 447 BOE, respectively, flowing up 4-1/2-inch casing. The well produced a total of approximately 51,000 BOE in its first six months of production. Whiting holds a working interest of 84% and a net revenue interest of 71% in the Federal well.

Niobrara Leasing and Exploration. Whiting has assembled a total of 55,000 gross (39,000 net) acres in northeastern Colorado that the Company believes to be prospective for Niobrara shale oil production. The Company expects to continue to actively lease in the area. Whiting anticipates drilling its first Niobrara well on this acreage in the first half of 2011.

The Company’s existing Niobrara exploration project, the Hatfield prospect in Carbon County, Wyoming, contains approximately 53,000 gross (32,000 net) acres. Whiting expects to spud two wells on the prospect in the second half of 2010. The Niobrara in this area is at a depth of approximately 3,500 feet, with Estimated Ultimate Recovery (EUR) of 100,000 – 125,000 BOE. Total estimated completed well costs are expected to range between $1.0 million and $1.5 million. These wells will be vertical tests. However, if these wells are successful, Whiting expects future wells to be horizontal and drilled on 160-acre spacing in order to increase EURs.

Operated Drilling and Workover Rig Count

As of July 20, 2010, 16 operated drilling rigs and 44 operated workover rigs were active on our properties. We were also participating in the drilling of six non-operated wells, three of which are Bakken wells in North Dakota and three of which are on the Gulf Coast of Texas, including one Eagle Ford test. We expect our operated drilling rig count to average approximately 17 during the remainder of 2010. The breakdown of our operated rigs is as follows:

Region	Drilling		Workover
Northern Rockies
Sanish Field		9		5
Other		3		6
Central Rockies
Flat Rock Field		1		1
EOR Projects
Postle		1		3
North Ward Estes		1		26

During the second quarter, the company-wide basis differential for crude oil compared to NYMEX was $8.21 per barrel, which compared to $8.07 per barrel in the first quarter of 2010. We expect our oil price differential to average between $8.50 and $9.50 during the third quarter of 2010. Within the Bakken, Whiting-operated production has a current differential of $11.00 per barrel.

The company-wide basis differential for natural gas compared to NYMEX in the second quarter was at a premium of $0.43 per Mcf, which compared to a premium of $0.33 per Mcf in the first quarter of 2010. We expect our natural gas to sell at a premium price of between $0.10 and $0.50 during the third quarter of 2010.

(1) Adjusted Net Income (Loss) Available to Common Shareholders is a non-GAAP financial measure. Management believes it provides useful information to investors for analysis of Whiting’s fundamental business on a recurring basis. In addition, management believes that Adjusted Net Income (Loss) Available to Common Shareholders is widely used by professional research analysts and others in valuation, comparison, and investment recommendations of companies in the oil and gas exploration and production industry, and many investors use the published research of industry research analysts in making investment decisions. Adjusted Net Income Available for Common Shareholders should not be considered in isolation or as a substitute for net income, income from operations, net cash provided by operating activities or other income, cash flow or liquidity measures under GAAP and may not be comparable to other similarly titled measures of other companies.

Discretionary cash flow (1)	$	442,718		$	181,642

(1) Discretionary cash flow is computed as net income plus exploration and impairment costs, depreciation, depletion and amortization, deferred income taxes, non-cash interest costs, non-cash compensation plan charges, non-cash losses on mark-to-market derivatives and other non-current items, less the gain on sale of properties, amortization of deferred gain on sale, non-cash gains on mark-to-market derivatives and preferred stock dividends paid. The non-GAAP measure of discretionary cash flow is presented because management believes it provides useful information to investors for analysis of the Company’s ability to internally fund acquisitions, exploration and development. Discretionary cash flow should not be considered in isolation or as a substitute for net income, income from operations, net cash provided by operating activities or other income, cash flow or liquidity measures under GAAP and may not be comparable to other similarly titled measures of other companies
