Abstract: The article shows that complications and accidents occurring in oil and gas wells in Russia during construction and operation in permafrost areas occur largely because of the lack of detailed data on the structure of the frozen section, permafrost conditions and, accordingly, lack of consideration of these during construction of wells and monitoring of wells interaction with frozen rock. The application of increasingly widely used method of processing of standard logging (ISKCON), allowing to analyze the frozen section without drilling special holes and without cryogenic coring in all wells of oil and gas fields to study the complex parameters of permafrost in the wells. The data obtained are presented in the catalogs, as well as maps and their three dimensional representations of deep geocryological conditions change over the fields area.
