ABSTRACT
The article points out that in order to reduce the interfacialtension at the boundary of oil with water, in order to improve its oil-leaching ability; various surfactants are added to the water injected into the reservoir. It has been shown in the literature that when a surfactant solution is filtered in a porous medium, part of it is adsorbed on the rock surface. This leads to a decrease in the effect of surfactants.The conducted experimental studies confirmed this position, on the basis of which recommendations were given for the selection of the amount of surfactants.
Keywords:SAM, surface tension, adsorption, molecular attraction.
