Basin Electric Cooperative completed a number of studies about the potential for CO2 enhanced oil recovery from North Dakota and Montana oil reservoirs in 1988 and 1990. (4)(5) The reports concluded that as of 1985 total OOIP in the 26 fields studied in Montana and North Dakota was 4,367 MMbo with cumulative recovery of 858 MMbo. Estimated total recovery from both primary and secondary oil recovery in the Montana and North Dakota fields was projected to be 1,038 MMbo using a 24.8% recovery of OOIP. This left 3,539 MMbo oil place at the end of primary and secondary recovery projects as of 1985. Future potential for CO2 miscible oil recovery for both Montana and North Dakota was stated to be 232 MMbo from 26 fields. On the basis of these studies the Dakota Gasification CO2 pipeline is now located along the Nesson Anticline. (6)
