... in early stages of production. The efficiency of oil recovery by waterflooding is strongly dependent on the complex interaction between oil, rock and brine and the balance of in-situ competing forces. Since mid-1990’s, evidences has grown that injecting low salinity water into petroleum reservoirs give...
