... the mentioned reservoir. Our novel work using the low salinity alternating steam flooding (LSASF) with the Bartlesville crude oil showed that a higher temperature could increase oil recovery, but the well–implemented procedure caused varied recoveries. The best heavy oil recovery was when the cycles of the LS...
