Lithological Models of The Bazhenov Formation in The North of The Khantheyskaya Hemianteclise Based on The Data of a Comprehensive Analysis of Geophysical Studies of Wells and Core Material

Summary The accumulation of fluid at the bottom of producing gas wells is one of the most pressing problems in the fields of the Far North, which are at the final stage of development and gas production. Water in a vaporous form comes from the reservoir into the well together with gas, condenses, and in the case of the upstream velocity in the column below the critical value, flows down to the bottom of the well. The accumulation of borehole water, which occurs at gas flow rates below a certain critical value, seriously complicates the technological process of gas production, dramatically reduces well flow rates up to spontaneous shutdown. This problem becomes more and more urgent every year, as the fund of such spontaneously stopping wells becomes more and more every year. One of the promising technological solutions to support the work of producing wells is the equipment of the trunk with concentric lift columns.
