Abstract An Almy sand polymer-augmented alkaline flood at the Isenhour Unit, Sublette County, WY, is reviewed. This paper updates process technology, including the use of clay stabilization, sweep improvement, soda ash alkaline agent (to reduce interfacial tension (IFT) and mobilize residual oil), and anionic-polymer-blend mobility buffer. Oil production has been increasing at 20%/yr since the process start.
