..., formation and injectivity decline of each technology. Two Anionic, two amphoteric surfactant, two alkalis and two types of polymers were used in this work to formulate the different chemical solutions. Core flow experiments using core samples of 1.5" diameter and 20" in length prepared from Berea sandstone...

... polymer flooding (LTPF) method to overcome some of the challenges caused by using high concentration of surfactant during some early SP flooding projects and to reduce the cost of operation. Amphoteric surfactant shows high thermal and chemical stability in these environments was evaluated in this study...
