ABSTRACT: A Lodgepole Play in North Dakota

The Lodgepole formation has been the major producing horizon in the Manitoba portion of the Williston basin, but it has not been a target in North Dakota except for limited interest along the northeast flank in early exploration. Completion of the Conoco-Dickinson State well 74, located in SW NW, Sec. 32, T140N, R96W, on February 3, 1993, for an IP of 2,045 bbl of oil, 164 mcf gas/day from the Lodgepole formation startled explorationists and requires a reexamination of Lodgepole stratigraphic concepts.

Lineback and Davidson (1982) proposed that the Illinois and Williston basins were sediment-starved basins during the Late Devonian through the middle Mississippian. Cross sections of the Lodgepole formation from basin margins to the central basin area are consistent with that model. Facies changes within the Lodgepole formation indicate that the recent discovery is in clinoform carbonates basinward from persistent argillaceous beds.
