Experiments on Effect of Water-Injection Rate on Imbibition Rate in Fractured Reservoirs

Abstract

Abstract Laboratory experiments using a model to simulate a fracture-matrix-type reservoir indicate a relationship between rate of water injection and rate of imbibition. Under conditions of linear countercurrent flow, increased rate of water injection resulted in increased imbibition rates and greater indicated ultimate recovery. The correlation between water-injection rate and imbibition appears to be well denned. The effects of temperature and the condition of the sand face exposed to imbibition were evaluated.
