Abstract
Summary
We investigated short-term rates of imbibition of water and long-term recovery by spontaneous imbibition for crude oil/brine/rock systems. Increasing the aging time and aging temperature decreased the early time rate of imbibition of water. Moderately water-wet plugs gave the highest recovery by long-term imbibition. We present photographic records of oil production at core surfaces, which are indicative of connectivity and capillary-pressure driving forces for imbibition.
