Abstract A sugar amine sulfonate surfactant (SAS) was used to enhance oil recovery by chemical flooding. The interfacial tension between an SAS solution and four kinds of crude determined. Oil (4) containing the largest amount medium chain length components most suitable candidate because IFT could be reduced ultralow range (10 −3 mN/m) at optimum NaCl concentration. Emulsions consisting adsorption density on sandstone were studied. Compared with A37 (alkyl ether sulfate), ws able form more stable emulsions equivalent in typical concentration Both data followed Langmuir isotherm model. increased apparent viscosity KY‐1500 (modified polyacrylamide) a low improve viscoelasticity. combination (SP) enhanced 16.05 versus 14.31% (using alone).
