A review of the performance of the North Stanley Polymer Demonstration Project has been completed. The objective of the cost-project was to evaluate the technical efficiency and economic feasibility of polymer-enhanced waterflooding as a tertiary recovery process in a highly heterogeneous and vertically fractured sandstone reservoir that has been successfully waterflooded and is approaching the economic limits of conventional waterflooding recovery. The ultimate incremental oil recovery from the project is estimated to be about 570,000 barrels (or approximately 1.4% of the original oil-in-place). This is significantly less than the original recovery predictions but does demonstrate that the project was technically successful. The lower-than-anticipated recovery is attributed principally to the extremely heterogeneous nature of the reservoir. One of the major objectives of this evaluation is to present an updated economic anlaysis of the North Stanley Polymer Demonstration Project. The updated economic analysis under current (mid-1982) economic conditions indicates that the North Stanley project would be commercially feasible if polymer injection had begun in 1982, rather than in 1976. Overall project operations were conducted efficiently, with a minimum of operational problems. The North Stanley polymer project provides a well-documented example of an actual field-scale tertiary application of polymer-augmented waterflooding in a highly heterogeneous reservoir.
