Abstract
Two recipes of surfactant compounds for different geological-physical conditions have been chosen: SNPX-95 and SNPX-9502. Two technologies u tilizing these compounds have been developed: bottom hole area stimula tion in injectors for injectivity increase; oil recovery enhancement u tilizing SNPX-95M. Field tests have been conducted in conditions of di fferent temperatures and mineralization of injected water. It is state d, that application of SNPX-95 agent for stimulation of the fields at the late stage of development has very high perspective.
