Enhanced Oil Recovery Process Including The Simultaneous Injection Of A Miscible Gas And Water
US Patent:
5634520, Jun 3, 1997
Filed:
May 8, 1996
Appl. No.:
8/646888

Assignee:
Chevron U.S.A. Inc. - San Francisco CA
International Classification:
E21B 4322
US Classification:
166402
Abstract:
An enhanced oil recovery process comprises of the at least periodic introduction of (i) a non-condensible gas preferably selected from among carbon dioxide, nitrogen, methane or mixtures thereof, and (ii) an aqueous drive solution, preferably brine, into a reservoir formation. In this process, the half cycle of non-condensible gas injection, prior to aqueous drive fluid injection, measured in hydrocarbon pore volume is less than 0. 25%. In this preferred embodiment, the non-condensible gas, e. g. , carbon dioxide, and water, are simultaneously injected into the formation.
