OXY USA submitted an application with the North Dakota Industrial Commission in September seeking approval to drill up to seven horizontal wells in each of seven contiguous 1,280-acre standup spacing units in the Crooked Creek field in western Dunn County. Three of the wells on each unit will target the Pronghorn formation. OXY indicated in April that it was planning to test the Pronghorn formation.
Of the other four wells on each unit, three will target the middle Bakken and the fourth will target the Three Forks. That configuration in seven spacing units will result in a total of 21 Pronghorn wells, 21 middle Bakken wells and seven Three Forks wells in the development. OXY reports an estimated ultimate recovery, based on middle Bakken data, of 319,000 barrels of oil per well.
