Whiting Petroleum Corporation Announces First Quarter 2011 Financial and Operating Results

Q1 2011 Production of 66.0 MBOE/D Up 10%
Over 59.9 MBOE/D in Q1 2010

Q1 2011 Production Totals 5.94 MMBOE

Lewis & Clark Hecker 21-18TFH Well Has Record
Three Forks IP of 3,612 BOE/D

Company Reports Q1 2011 Net Income Available to Common Shareholders of $19.1 Million or $0.16 per Diluted Share and Adjusted Net Income of $99.7 Million or $0.84 per Diluted Share

Q1 2011 Discretionary Cash Flow Totals $284.1 Million

DENVER – April 27, 2011 – Whiting Petroleum Corporation’s (NYSE: WLL) production in the first quarter of 2011 totaled 5.94 million barrels of oil equivalent (MMBOE), of which 4.77 million barrels were crude oil/natural gas liquids (80%) and 1.17 MMBOE was natural gas (20%).  This first quarter 2011 production total equates to a daily average production rate of 66,005 barrels of oil equivalent (BOE), which represents a 10% increase over the 59,865 BOE average daily rate in the first quarter of 2010.  Compared to the fourth quarter of 2010, production was down only 3% as efforts by employees and contractors almost entirely offset the effects of extreme cold and snow that caused well completion delays in North Dakota and cold temperatures that caused downtime at our EOR projects in Oklahoma and Texas.
 
 
 

 
 
Financial Results
Discretionary cash flow in the first quarter of 2011 totaled $284.1 million, representing an increase of 32% over the $214.6 million reported for the same period in 2010.  The increase in discretionary cash flow in the first quarter of 2011 versus the comparable 2010 period was primarily the result of our 10% production increase and a 17% increase in the Company’s realized oil price (net of hedging), including the price of natural gas liquids (NGLs).  A reconciliation of discretionary cash flow to net cash provided by operating activities is included later in this news release.

In the first quarter of 2011, Whiting reported net income available to common shareholders of $19.1 million, or $0.16 per basic and diluted share, on total revenues of $432.2 million.  This compares to net income available to common shareholders of $81.2 million, or $0.80 per basic share and $0.73 per diluted share, on total revenues of $351.3 million in the first quarter of 2010.

The Company’s first quarter 2011 results include after-tax unrealized derivative losses of $77.8 million, or $0.66 per diluted share.  Excluding this loss and certain other items, Whiting reported first quarter 2011 adjusted net income available to common shareholders of $99.7 million, or $0.85 per basic share and $0.84 per diluted share.  This compared to first quarter 2010 adjusted net income available to common shareholders of $62.3 million, or $0.61 per basic share and $0.57 per 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.

James J. Volker, Whiting’s Chairman and CEO, commented, “We believe that we’re in a strong position to grow production and reserves during the remainder of 2011.  We believe the combination of our drilling plays and our two EOR projects provides a diversified mix of organic growth opportunities and long-term, reliable cash flow.  We added 37,000 net undeveloped acres in the Bakken / Three Forks Hydrocarbon System of the Williston Basin during the first quarter and now hold 458,000 net undeveloped acres.”

Mr. Volker continued, “We are pleased with our results at the Lewis & Clark prospect, which have averaged initial production rates of 1,111 BOE per day for our eight new wells.  The results of the Hecker well at 3,612 BOE per day are especially encouraging.  We hold more than 375,000 gross and more than 245,000 net acres in the prospect area and currently have five operated drilling rigs working at Lewis & Clark.  We plan to bring that number to nine by the third quarter of 2011.  With these key projects, we are optimistic about Whiting’s operational results in 2011 and beyond.”

Whiting’s net production from the Middle Bakken and Three Forks formations in the Sanish and Parshall fields of Mountrail County, North Dakota averaged 26,010 BOE per day in the first quarter of 2011, in the face of extreme weather, a decrease of 7% from the 28,020 BOE average daily rate in the fourth quarter of 2010 and an increase of 20% from the 21,690 BOE average daily rate in the first quarter of 2010.

Sanish Field. Whiting owns 108,269 gross (66,253 net) acres in the Sanish field, located in Mountrail County, North Dakota.  Whiting’s net production from the Sanish field in the first quarter of 2011 averaged 21,685 BOE per day, a decrease of 8% from the fourth quarter 2010 average rate of 23,465 BOE per day.  The decrease was due to well completion delays from inclement weather in North Dakota.  Compared to the first quarter 2010 average rate of 15,180 BOE per day, production in the first quarter of 2011 was up 43%.  Our net production from the Sanish field averaged 21,905 BOE per day in March 2011, a 2% decrease from 22,270 BOE per day in December 2010.

From January 1 through April 15, 2011, Whiting completed 15 operated Bakken wells and seven operated Three Forks wells in the Sanish field, bringing to 158 the number of Whiting-operated wells in the field as of April 15, 2011.  Including non-operated wells, there were 226 producing wells in the Sanish field as of April 15, 2011.  The Company plans to continue with its current nine operated drilling rig count in the Sanish field through 2013.  In 2011, Whiting intends to drill 95 operated wells (54 net wells) in the field, of which 70 are planned Three Forks wells, 15 are cross-unit Bakken wells, seven are Bakken infill wells and three are wing wells.  Whiting has contracted two full-time dedicated frac crews in North Dakota.  The Company estimates that each crew is capable of fracture stimulating 100 wells per year.  As of April 15, 2011, 17 operated wells and seven non-operated wells were being completed or awaiting completion and nine operated wells and one non-operated well were being drilled in the Sanish field.

Highlighting recent results at our Sanish field was the Smith 14-29XH, which was completed in 40 separate stages, all with sliding sleeves.  The new downhole assembly was provided by Baker Hughes.  This was the first 40-stage frac in the world utilizing sliding sleeve technology, according to Baker Hughes.  The 40-stage frac was completed in approximately 26 hours.  The Smith well, located in the southwest portion of the Sanish field, was tested on April 2, 2011 flowing 1,805 barrels of oil and 1,338 Mcf of gas (2,028 BOE) per day from the Bakken formation.  The flow rate was gauged on a 48/64-inch choke with a flowing casing pressure of 700 psi.  Whiting holds a 43% working interest and a 35% net revenue interest in the Smith well.

Whiting also recently completed its first wing well (a shorter lateral well located in the corner of a spacing unit). The Ness 42-31WH, located in the southwest portion of the Sanish field, was completed on March 16, 2011 flowing 1,327 barrels of oil and 1,209 Mcf of gas (1,529 BOE) per day from a 6,833-foot lateral.  A typical Whiting-operated Bakken well in the Sanish field has a 10,000-foot lateral.  The flow rate was gauged on a 48/64-inch choke with a flowing casing pressure of 351 psi.  Whiting operates the well, holding a working interest of 73% and a net revenue interest of 60%.

We also completed the Hoover 14-1XH.  This cross-unit well flowed 2,043 barrels of oil and 1,013 Mcf of gas (2,212 BOE) per day from the Bakken formation on March 21, 2011.  The flow rate was gauged on a 40/64-inch choke with a flowing casing pressure of 373 psi.  The Hoover 14-1XH was fracture stimulated in a total of 22 stages, all using sliding sleeves.  An additional eight stages will be performed using the plug and perf method.  Whiting operates the Hoover 14-1XH, holding a working interest of 27% and a net revenue interest of 22%.

The 17-mile oil line connecting the Sanish field to the Enbridge pipeline in Stanley, North Dakota is currently transporting approximately 33,000 barrels per day, which represents approximately 90% of Whiting’s gross operated Sanish production.  This 8-inch diameter line has a capacity of approximately 65,000 barrels of oil per day.  The Company is currently saving between $1.00 and $2.00 per barrel in transportation costs for each barrel that is transported through the pipeline rather than being transported by truck.     Enbridge is awaiting regulatory approval to add an incremental 25,000 barrels per day for a total of 210,000 barrels per day of take-away capacity.

Robinson Lake Gas Plant.  Whiting’s Robinson Lake Gas Plant is currently processing 34.8 MMcf of gas per day (gross).    Whiting expects the plant’s inlet capacity to be expanded to 90 MMcf per day in the third quarter of 2011.  Whiting owns a 50% interest in the plant.  The plant receives 25% of the net proceeds from third-party natural gas and NGLs processed at the plant.  As of April 15, 2011, sales from the plant were 28.5 MMcf of gas and 3,927 barrels of NGLs per day, from which Whiting was netting 3.6 MMcf of gas and 491 barrels of NGLs per day due to its 50% plant ownership and the plant’s 25% net-of-proceeds contract.

Lewis & Clark Prospect Area. Whiting owns 376,111 gross (245,744 net) acres in the Lewis & Clark area, located in Golden Valley, Billings and Stark Counties, North Dakota.  We hold a working interest in 250 1,280-acre spacing units.  In 164 of the units, Whiting owns a controlling interest with an average working interest of 64%.  We estimate two to four wells per 1,280-acre spacing unit are required to fully develop this area.  We currently have five drilling rigs operating in this project, and we expect to average nine rigs working in July through December.

From January 28 through April 18, 2011, Whiting completed eight additional wells at its Lewis & Clark prospect.  Results of these eight wells are as follows:

The Hecker 21-18TFH, during a 24-hour test of the Three Forks formation at a vertical depth of approximately 10,500 feet on March 4, 2011, flowed at a daily rate of 3,106 barrels of oil and 3,038 Mcf of gas, or 3,612 BOE per day.  This is the highest initial production rate for a Three Forks well in the Williston Basin, according to Harts Unconventional Oil & Gas website.  The initial 24-hour production rate was gauged on a 48/64-inch choke with a flowing casing pressure of 990 pounds per square inch (psi).  The well was fracture stimulated in a total of 22 stages, all using sliding sleeve technology.  An additional eight stages are scheduled to be fraced with the “plug and perf” method.  Whiting, the operator of the well, holds a 77% working interest and a 62% net revenue interest in the new producer.

Due to mechanical difficulties at the Obrigewitch 21-17TFH, Whiting believes that only one or two frac stages of the well’s total 16 frac stages are contributing to current production.  Despite these difficulties, the Obrigewitch well was completed flowing 1,189 BOE per day.  Whiting holds a 96% working interest and a 77% net revenue interest in the well.

Whiting experienced a similar situation at the Mosser 11-27TFH.  We believe that an estimated eight frac stages of the well’s total 30 frac stages were contributing to the well’s initial production.  We recently moved in a workover rig to this well and performed a wellbore cleanout.  We continue to believe that a limited number of frac stages are contributing to the well’s current production and are in the process of installing a pumping unit on the Mosser well.  We plan to continue to monitor and evaluate the well’s performance.

The other Three Forks wells in the table above exhibit variations in initial production rates reflecting rock quality and pressure differences which vary across the 376,111 gross acre Lewis & Clark position.  We continue to refine our Lewis & Clark completion procedures in an effort to improve IPs and EUR.  To date, we are pleased with all of our Lewis & Clark Three Forks results which have average initial production rates of 1,111 BOE per day and compare favorably with our 17 Sanish field Three Forks wells which had average IPs of 1,142 BOE per day.

New Belfield Gas Plant.  Earlier this month, Whiting broke ground on the construction of a gas processing plant at Lewis & Clark.  The Belfield Gas Plant, located near Belfield, North Dakota, will have an initial inlet capacity of 30 MMcf of gas per day and is expected to be completed by November 2011.  To reduce the volume of gas being flared in the Lewis & Clark area, we are in the process of installing equipment to compress the natural gas into vessels that can be trucked to the nearest gas plant.  Our Belfield plant will have the capability to accept this trucked gas.

Core Williston Basin Land Position.  Whiting increased its core acreage position in the Bakken / Three Forks Hydrocarbon System of the Williston Basin to 891,678 gross acres from 829,015 gross acres and to 560,921 net acres from 521,525 net acres.    Whiting also holds an additional 42,781 net acres of prospective Bakken and Three Forks acreage in other areas of the Williston Basin.
 
EOR Projects
 
North Ward Estes Field.  As of January 1, 2011, Whiting began to accelerate its CO2 project at the North Ward Estes field, located in Ward and Winkler Counties, Texas.  The Company plans to have all eight phases of its CO2 project implemented by 2016.  The first two phases were largely completed by December 2009, and Phase 3 began in December 2010.  Whiting believes that, in addition to improving the net present value of future production from the field, we will be able to increase production and convert probable and possible reserves to proved reserves at a faster pace.  At year-end 2010, a total of 130 MMBOE of probable and possible reserves were assigned to the North Ward Estes field.

Production from our North Ward Estes field averaged 8,120 BOE per day in the first quarter of 2011.  This average rate represented an 8% increase from the 7,530 net daily rate in the first quarter of 2010.  Production in March 2011 averaged 8,580 BOE per day, an increase of 13% from the December 2010 average daily rate of 7,620 BOE.  As a result of additional compression and increased CO2 injection, production from the field has increased.  Whiting is currently injecting approximately 260 MMcf of CO2 per day into the field, of which about half is recycled gas.  As of April 15, 2011, one drilling rig and 33 workover rigs were active in the field.

Postle Field.  The Postle field, located in Texas County, Oklahoma, produces from the Morrow sandstone at a depth of approximately 6,500 feet.  In the first quarter of 2011, the field produced at an average net rate of 8,455 BOE per day.  As a result of normal CO2 injection variations this represents a decrease of 5% from the average daily rate in the fourth quarter of 2010.  We recently increased CO2 injection into the field and expect moderate production increases over the next two to three months.

New Prospect Drilling Areas

Redtail Niobrara Prospect. As of April 15, 2011, Whiting had acquired 102,920 gross (74,741 net) acres in our Redtail Niobrara prospect in the Weld County, Colorado portion of the Denver Julesburg Basin.  We are continuing to acquire acreage.  Our average acreage cost to date is $468 per net acre, and we have an average working interest of 73% and an average net revenue interest of 61%.

In late 2010, we initiated a seven well exploratory drilling program that will continue through June 2011 and will consist of two vertical pilot wells and five horizontal production wells.  Based on our current acreage position and a successful exploratory program, we could operate up to 220 wells and participate in an additional 131 non-operated wells assuming 320-acre spacing.  Drilling depths in this area range from 5,500 feet to 6,500 feet with completed well costs for a 5,000-foot horizontal Niobrara well estimated at between $4 million and $5 million.  We currently have one drilling rig running at the Redtail prospect.

Whiting has drilled five wells to date.  The following table summarizes our plans and results to date:

We consider this play to be in an early stage.  Further drilling is subject to evaluation of our drilling and completion results.

Big Tex Prospect.  As of April 15, 2011, Whiting had accumulated 111,665 gross (83,303 net) acres in our Big Tex prospect area in Pecos, Reeves and Ward Counties, Texas in the Delaware Basin.  We are also continuing to acquire acreage in this area.  Our average acreage cost to date is $516 per net acre, and we have an average working interest of 75% and an average net revenue interest of 56%.  We have completed 10 vertical wells over the past nine months in the southern portion of the Delaware basin.  Prospective formations include the Wolfcamp and Bone Spring horizons.

Our first vertical well in this area, the Trainer Trust 16-2, had a peak flow rate of 816 BOE per day and continued to flow for six months, producing over 45,000 barrels of oil during its first six months of production.  The well produced at a restricted rate for 45 days during that period.  Subsequently, nine vertical wells have been completed with average initial production rates of 283 BOE per day.  We have four drilling rigs in Big Tex and recently kicked off a four-well horizontal drilling program.  We consider this play to be in an early stage.  Further drilling is subject to evaluation of our drilling and completion results.

Notable  Financial Events

On April 15, 2011, we closed an amendment to our $1.1 billion Bank Credit Agreement that lowered the interest rate by 25 basis points, the commitment fees by 12.5 basis points and extended the facility six months to April 15, 2016.  All of the 19 banks in our syndicate reaffirmed at their existing levels.

On January 26, 2011, our Board of Directors approved a two-for-one split of the Company's shares of common stock to be effected in the form of a stock dividend. As a result of the stock split, stockholders of record on February 7, 2011 received one additional share of common stock for each share of common stock held. The additional shares of common stock were distributed on February 22, 2011. All share and per share amounts in this news release for periods prior to February 2011 have been retroactively adjusted to reflect the stock split.

During the first quarter, the company-wide differential for crude oil/NGLs compared to NYMEX was $12.41 per barrel, which compared to $10.59 per barrel in the fourth quarter of 2010.  In large part, this differential increase was caused by increasing volumes of NGLs at our Robinson Lake Gas Plant and our North Ward Estes field. NGLs, which are included as a component of our crude oil sales, now account for more than 10% of our liquids production. Because NGLs receive a price that approximates 60% of the price of crude oil, an increasing percentage of NGLs will have a negative (widening) effect on our crude oil differential. The differential on true crude oil sales (no NGLs) in the first quarter was $8.84 per barrel.  We expect our company-wide oil price differential to average between $10.00 and $11.00 during the second quarter of 2011.  Within the Bakken, Whiting’s operated production has narrowed to a differential of approximately $5.50 per barrel in April 2011.  This was due to the Horizon Pipeline, which transports heavy crude from Canada, being down or transporting crude at a restricted rate.  This situation is expected to continue through the second quarter of 2011.

The company-wide basis differential for natural gas compared to NYMEX in the first quarter was at a premium of $0.90 per Mcf, which compared to a premium of $0.53 per Mcf in the fourth quarter of 2010.  We expect our natural gas to sell at a premium price of between $0.50 and $0.80 during the second quarter of 2011.

Adjusted net income available to common shareholders per share, diluted (2)
  $ 0.84     $ 0.57  

 (1)  
Adjusted Net Income 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 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 is computed as net income plus exploration and impairment costs, depreciation, depletion and amortization, deferred income taxes, non-cash interest costs, loss on early extinguishment of debt, 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, not including the preferred stock inducement premium.  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.
