Abstract

A method of improving oil or gas well productivity from a well penetrating a formation in an oil or gas reservoir, by injecting a stream of liquified drive fluid into the well ahead of a load fluid to establish a miscible bank of drive fluid in the well. While injecting the stream of liquified drive fluid into the well, a load fluid in which the liquified drive fluid is miscible is injected into the well mixed with the liquified drive fluid. The ratio of liquified drive fluid to load fluid is initially at a level sufficient to form a miscible bank of drive fluid in the gaseous state ahead of the load fluid in the well. Subsequently, the ratio of liquified drive fluid to load fluid injected into the well is reduced.
