Whiting Petroleum recently completed two new producers at its Lewis & Clark Prospect in Stark, Billings and Golden Valley Counties, North Dakota.

During a 24-hour test of the Three Forks formation at a vertical depth of approximately 10,500 feet on September 18, 2010, the Froehlich 44-9TFH flowed at a daily rate of 1,832 barrels of oil and 1,546 Mcf of gas, or 2,090 barrels of oil equivalent (BOE) per day. The initial 24-hour production rate was gauged on a 42/64-inch choke with a flowing casing pressure of 824 pounds per square inch (psi). The well was fracture stimulated in a total of 28 stages, all using the 'plug and perf' method. Whiting, the operator of the well, holds a 90% working interest and a 73% net revenue interest in the new producer.

The Kubas 11-13TFH, located approximately five miles northeast of the Froehlich well, was tested on September 13, 2010 flowing at a daily rate of 1,780 barrels of oil and 1,035 Mcf of gas, or 1,953 BOE per day from the Three Forks formation. The 24-hour test was gauged on a 46/64-inch choke with a flowing casing pressure of 520 psi. The Kubas well was fracture stimulated in a total of 29 stages, 21 stages using sliding sleeve technology and the remaining eight stages using the 'plug and perf' method. Whiting operates the Kubas 11-13TFH, holding a working interest of 90% and a net revenue interest of 73%.

Both the Kubas and Froehlich wells were drilled on the southeast portion of the Lewis & Clark Prospect in Stark County, North Dakota. The wells are located approximately 32 miles southeast of Whiting’s Federal 32-4TFH discovery well, which flowed 1,970 BOE per day from the Three Forks formation on November 25, 2009.

A third well on the Lewis & Clark prospect, the Ellison Creek 11-1TFH, is currently being completed. This well was drilled approximately three miles east of the Federal 32-4TFH. Whiting plans to release the results of the Ellison Creek 11-1TFH and three other Lewis & Clark wells in mid-November.

James J. Volker, Whiting's Chairman, President and CEO, commented, "We are very pleased with our recent results at the Lewis & Clark Prospect. We currently hold more than 340,000 gross and 225,000 net acres in the prospect area. We currently have four operated drilling rigs at Lewis & Clark and plan to bring that number to five by mid-November."
