The article considers the issues related with operations aimed at water isolation in Cenomanian wells. The analysis of methods of water isolation jobs including creation of technological screens and hydrophobization of the productive bed was carried out. It is pointed out that in the conditions of gas production decline and the reservoir pressure drawdown some methods can be used designed for prevention of reservoir water influx in the gas wells. These methods are described in the article.
