Habitat of Rival oil in Burke County, North Dakota
The Mississippian Rival beds are a shallowing-upward limestone to evaporite sequence in Burke County, North Dakota. Rival oil production in this part of the basin occurs from shoreline carbonates and podshaped algal banks that developed seaward of shoreline evaporites. Shoreline carbonates, which produce in the rival and Foothills fields, consist predominantly of grainstones with well-preserved intergranular porosity. The updip trapping facies in these shoreline trends is anhydrite. Occluding cements are principally anhydrite, baroque dolomite, and prismatic calcite spar. Cumulative oil production is over 13 million bbl in the Rival field, where good porosity, permeability, and an effective trap are present. Algal-bank sediments are productive in Black Slough, Tioga, and North Tioga fields. Peloidal, skeletal, and algal packstones and grainstones in these fields contain intergranular, moldic, and vuggy porosity. Occluding cements are fibrous calcite, prismatic calcite spar, and baroque dolomite. Impermeable mudstones and wackestones, which surround the algal banks, are the trap facies. Rival oil production from the Tioga field is over 14 million bbl. Potential for production exists in both shoreline and algal bank sequences of the Rival beds in the southern and western parts of Burke County. Prospective targets occur where depositional trends cross well-defined paleostructural features.
