A METHOD FOR INCREASING THE OILRECOVERY FROM ACTIVE WATER DRIVERESERVOIRS(D#70,488-1-Cl-F )ABSTRACT OF THE DISCLOSUREA method is provided for increasing oil recoveryfrom reservoirs which have an active water drive so that thereservoir pressure remains essentially constant during theproduction of oil from the reservoir. The method entailsestablishing a free gas saturation by injecting a hot fluidinto the reservoir so that bubbles of gas will form due tothe increased temperature and be held suspended in thereservoir. An additional amount of oil about equal to theirreducible gas saturation will be displaced by the encroachingaquifer and produced.-I-
