The formation of gas hydrate deposits on the inner surface of gas production equipment is a frequently occurring type of complication in gas production, leading to a significant decrease in the useful section of pipes and gas pipelines. The intensity of their formation can lead to a complete overlap of the lifting pipes and annular channels in the annulus in certain areas, which necessitates repair work to clean the wells of gas hydrates. Based on the analysis of methods for cleaning wells from gas hydrate deposits, it was revealed that in some cases one of the effective methods of preventing their formation and combating them is to use the energy of high-frequency and superhigh frequency electromagnetic fields. The article explores the processes of heating and decomposition of gas hydrate deposits in the wellbore. About 30% of the thermal energy released in the wellbore interacting with the electromagnetic field is consumed to heat the medium surrounding the well. The need for timely removal of the gas-water mixture formed in the annulus for the decomposition of gas hydrate along the entire length of the well is established.
