Oil recovery by the injection of water alternately with gas (WAG flooding) is often limited by gravity segregation, which causes the injected gas to rise to the top of the formation and water to migrate to the bottom. This segregation results in a miscible flood in only a thin layer at the top of the formation, whereas the remainder is waterflooded. However, vertical conformance in a WAG flood can be improved by use of injection rates that are high relative to well spacing. The degree of improvement and the resultant oil recovery is primarily a function of a single dimensionless parameter, which is one form of the viscous-gravity ratio.
