Filed:
Oct 12, 1976
Appl. No.:
5/731777
Inventors:
Amir M. Sarem - Yorba Linda CA

US Classification:
166270
Abstract:
A process for recovering petroleum from subterranean reservoirs where high salt content water is used in a secondary recovery process consisting of forming as the displacement fluid a dilute alkaline silicate solution utilizing the high salt content water and filtering the alkaline flooding solution to remove scale-forming alkali insoluble salts which include a substantial proportion of calcium and magnesium salts. The filtered solution is injected into the reservoir and this is followed by an injection of a slug of substantially neutral water. A dilute acid solution is utilized to contact and dissolve the alkaline insoluble salts which have been filtered from the alkaline solution and the thus formed solution which includes a substantial portion of soluble calcium and magnesium salts is injected into the reservoir for subsequent contact with the alkaline silicate solution. This contact results in the formation of precipitates which partially plug that portion of the reservoir in which the contact occurs and reduces the permeability thereof. The process is repeated a plurality of times until the desired amount of alkaline silicate solution has been injected into the reservoir whereupon untreated water can be injected as a drive fluid.
