Evalution of Wettability Alteration as Mechanism to Induce Oil Recovery by Using Greenzyme - biochemical agent

Abstract

Several laboratory experiments indicated that interfacial tension reduction between oil and water or oil and solid surface by chemicaland biochemical flooding can improve oil recovery. Enzymes flooding are promising method for improving oil recovery in sandstone reservoirs with much less safety and environmental hazards and low cost on addition to its availability and ease of composition. This research presents laboratory results and analysis of core flood to evaluate how Greenzyme affect wettability. The experiment was done in tertiary recovery mode and the results show an obvious improvement in oil recovery due to change in wettability applied to core samples A,B and D. the recovery factor increased from 41.32 to 56.47, 39.41 to 46.75 and 43.57 to 53.13 percentages respectively.
