Whiting Petroleum Corp., an independent oil company with headquarters in Delaware, said it uncovered new sources of oil at its field in North Dakota.
A test well drilled to a vertical depth of roughly 10,500 feet yielded 1,832 barrels of oil and 2,090 barrels of oil equivalent per day of natural gas during a 24-hour test.
A second well drilled about 5 miles north of that site produced 1,780 barrels of oil and 1,953 barrels of oil equivalent per day of natural gas.
Both wells were drilled in the same prospect in southwest North Dakota. The company plans to build a 40-mile pipeline in Stark County, N.D., where it expects to drill as many as 100 oil wells.
James Volker, the top executive at Whiting, said his company was "very pleased" with the latest developments at its North Dakota prospects.
