The article describes features of magnetotelluric scanning of the Earth's crust while searching and exploring hydrocarbon deposits. The text gives valuable information on possibilities of magnetotelluric method in the study of the Earth's crust.

The article contains information on the determination of the specific electrical resistivity of rocks by scanning magnetotelluric sounding method while searching for and exploring hydrocarbon deposits.

In the article principal problems of Cenomanian gas reservoirs exploitation on the last stage are considered. On the base of primary data analysis the dependence of a gas saturation factor from vertical reservoir location against gas water contact is determined which has influence on the gas well exploitation method. The necessity of maintenance of a net gas pay in a productive layer remaining the same during water shutoff treatment is proved. A new approach for realization of water shutoff treatment within low-pressure gases exploitation is justified.
