Abstract: The article presents the results of a computational study of the influence of gas-liquid systems on the rate of permafrost thawing during drilling. The influence of various factors on the process of thawing of the borehole zone during well drilling is studied. The influence of gas content in foam on the thermophysical characteristics of solutions and on the rate of permafrost thawing during drilling is analyzed. The influence of the concentration of various additives on the properties of foams and the process of permafrost thawing during drilling is analyzed. It is shown that by adding various chemical reagents it is possible to influence the thermophysical and rheological properties of gas-liquid systems, which can have a favorable effect on the rate of permafrost thawing during drilling
