ABSTRACT

The Indian Hill Field area (which includes Hardscrabble Field and a portion of Camp Field) is located on a southeast plunging anticline in northwestern McKenzie County and southwestern Williams County, North Dakota. Production was established in 1978 followed by the addition of 5 shallower producing zones in the early 1980s. The productive area is approximat l 10 miles long and up to 3.5 miles wide with production from Paleozoic carbonate reservoirs. The primary objectives are Ordovocian Red River, Silurian Stonewall, Devonian Duperow, and Mississippian Mission Canyon; and the secondary objectives are Devonian Nisku and Mississippian Ratcliffe. Productivity and reservoir development are highly variable. In general, the Red River "D" zone and the Duperow produce along the flanks of the structure whereas the Red River "C" and "B" zones, the Stonewall, and the better Mission Canyon produce from the crest of the structure. Cumulative production through December 1986 is 8.6 MMBO.
