چکیده:

Unwanted water production in association with crude oil is one of the major production difficulties for the petroleum industry, as more reservoirs become mature. Various chemicals have been used as blocking and diverting agents to treat injection and production wells for more than six decades. In this paper we provide a brief overview of some important chemical water shut off systems such as Inorganic gel, resin, natural polymer, polymer gel and ungelled polymers that are being used up to now. Finally, performance of different polymer gels as water shut off system that nowadays widely is practiced to improve production of oil and gas was evaluated
