The article is devoted to a computational experiment on forecasting the thermal interaction of a group of gas wells and permafrost. In connection with the spread of cluster drilling, it becomes necessary to study the thermal effect of a cluster of wells on frozen soils in the specific conditions of Central Yakutia. As input data for the numerical survey, field data on thermal logging, production rates, physicochemical properties of gas, rock properties and parameters of the developed deposits were used. Quantitative results were obtained on the extent and pattern of thawing of frozen rocks in the vicinity of the group of wells, and on well operation modes. The results of the work can be used in planning the development of gas fields in the considered area.
