Application of water-base surfactants with high wash-off capacity for well injectivity increase and oil recovery enhancement
Two recipes of surfactant compounds for different geological-physical conditions have been chosen: SNPX-95 and SNPX-9502. Two technologies utilizing these compounds have been developed: bottom hole area stimulation in injectors for injectivity increase; oil recovery enhancement utilizing SNPX-95M. Field tests have been conducted in conditions of different temperatures and mineralization of injected water. It is stated, that application of SNPX-95 agent for stimulation of the fields at the late stage of development has very high perspective.
