Abstract

In an on-going steam assisted gravity drainage process for recovering oil from a subterranean reservoir, vapors from a wellhead separator are compressed with high pressure plant steam using an eductor, to produce a mixture that is injected into the reservoir. As a result, heat contained by the vapors is efficiently utilized.
