Enhanced Oil Recovery

257 result(s) found.

enhanced oil recover  Enhanced oil recovery (EOR), a stage of hydrocarbon production that involves use of sophisticated techniques to recover more oil than would be possible by utilizing only primary production or waterflooding. EOR encompasses a range of techniques used to restore formation pressure and improve hydrocarbon displacement or fluid flow in the reservoir. Definitions in this discipline range from adsorption to waterflooding. All definitions have been reviewed by EOR experts, and many are accompanied by high-quality illustrations.
