Title: Williston Basin: Mississippian Reservoir Characteristics and Proved Reserves

Author(s): H. Mack Cox (2)


Since the discovery of oil in the Madison limestone in the Clarence Iverson well in December, 1951, it has been estimated that reserves of nearly 200 million barrels in the Mississippian formations alone have been established in the Williston basin. This is almost twice the combined new reserves of all other Rocky Mountain areas for the same period. It is predicted that by the end of 1955, the Mississippian reserves will be more than ½ billion barrels or approximately 1/3 the present reserves of Oklahoma. The basis for this prediction is the variety of favorable reservoir characteristics of the Madison-Charles section. The producing formations are fractured limestone, granular limestone with pin-point porosity, and fossiliferous vuggy limestone in rich source beds. A cumulation is not entirely dependent on structure or large closure as in most other Rocky Mountain areas.
