Annotation:
The article describes the results of field experiments and laboratory studies carried out at the Zarechnoye field in order to stabilize oil production, reduce its water cut by pumping standard and new reagents during 2004–2021. Information is presented on the developed reagents for the surfactant "Divoil-S35", the composition of the water repellent "S-1", which were used individually and in combination at the second and third stages of development. At the fourth stage of development, field tests were carried out on the injection of micellar solutions. According to the results of laboratory tests, the "Surfax-P" solution on formation water was selected. The obtained positive results of field trials made it possible to recommend wider use of micellar flooding.
