Canada's Pembina Field

Abstract

JOHN J. JUSTEN MEMBER AIME The Pembina field is the largest in Canada and one of the largest in the North American continent. Much of the published data concerning this reservoir is compared and summarized such that the geological, rock, and crude characteristics are indicated. The reservoir was initially undersaturated. The production history is reviewed. The natural recovery mechanism is indicated to be solution gas drive. Engineering studies indicate that the ultimate recovery for various areas will be more than doubled if pressure is maintained by water flooding. With pressure maintenance the field will be in the billion barrels reserve class. Pressure maintenance operations have commenced in various areas, using the existing wells in a 160-acre, five-spot pattern. A response to water injection has been reported in one area. By the end of 1957 about 50,000 acres will be under flood with water obtained from the North Saskatchewan River.
