Abstract
Background In the oil and gas complex the surface-active agents (surfactants) are used for treatment of bottomhole formation zone, and in the combined methods of increasing the oil recovery factor (ORF). In order to stimulate the oil well production the surfactants, their mixtures or different compositions could be used in terms of their lower environmental risk. Aims and Objectives Research and development of environmentally sound technologies of application of composite surfactant systems for the intensification of oil displacement. Methods Laboratory studies of the properties of composite systems surfactants. Experimental investigations and optimization of surfactant composite system structures in order to increase the oil recovery. Conclusion On the basis of experimental studies the environmentally friendly technology is designed which increases oil recovery from oil deposits.
