Abstract

A method of improving a steam drive wherein high-quality steam is initially injected into a hydrocarbon-bearing formation to initiate a steam drive from an injection well to a production well and then very low-quality steam or water is injected into the formation until the cumulative value of quality of all the injected fluid is reduced to a value between 35 and 45% to maximize the heat utilization of the steam in the formation and improve the sweep efficiency of the steam drive and then adjusting the quality of the steam injected into the formation to a value of between 35 and 45% to continue the steam drive.
