A practically significant approach has been identified, a concept was developed, as well as the necessary conditions for pumping water into the gas cap. An analysis of the impact of water injection into the gas cap on the wells of ringing was carried out. The water injection efficiency monitoring program has been developed.</em></p>offshore fieldgas capinjection systemморское месторождениегазовая шапкасистема закачки[Поляков Д.В., Хисматуллина Ф.С., Солодов П.А.
