Abstract
Field oil recovery performance of a mobility control chemical flood can be predicted by laboratory displacement tests. Four variations comparing field results with laboratory coreflood results are: 1.) A large polymer-flood pilot in S.W. Saskatchewan involving 5 injection wells and 13 production wells. 2.) An alkaline-polymer flood in Alberta with 25 wells of which 7 were injectors. 3.) A secondary application of alkaline-surfactant-polymer in a 6 production well, 1 injection well Wyoming reservoir. 4.) An alkaline-surfactant-polymer flood of 4 inverted 5-spots in a waterflooded Chinese field. The comparison of laboratory and field results is based on oil cut and oil recovery performance. Results of comparisons suggest that radial corefloods physically simulate oil recovery process in the field when properly scaled.
