This paper reviews the effect of brine composition on LoSal™ EOR waterflood recovery. An improved understanding of the LoSal™ mechanism is presented. Corefloods and single-well tracer tests were performed to evaluate the mechanism and quantify recovery benefits. It was determined that recovery is a function of water chemistry and formation mineralogy. Project economics are significantly enhanced by injecting a slug of low salinity water versus continuous injection. It was determined that a 40% slug by pore volume is fully effective. The work presented in this paper was done to quantify tertiary LoSal™ EOR benefits at the Endicott field located on the North Slope of Alaska. An interwell test is currently underway to unambiguously measure LoSal™ EOR response at field scale. |
