Abstract
Summary: Experimental methods are presented to evaluate and to measure the major contributions to surfactant and polymer losses in Berea sandstone for various oil saturations (no oil to postwaterflood residual oil). The results of linear displacement experiments are shown, and chemical losses evaluated for various sequences of injected fluids. Surfactant and polymer losses are evaluated independently, then for simultaneous injection into the core. When oil is present, chemical losses are related to phase behavior properties with salinity requirement diagrams.1 Both a synthetic white oil and a reservoir stock-tank crude oil are used in the experiments.Keywords
