Hydrodynamic modeling of the Yarega oilfield block was considered for the first time. The block is developed by thermo-mining method. Influence of dissolved gas in oil on technological indicators of development is considered. The positive effect was revealed of dissolved gas on oil production. The mode of the dissolved gas is activated when heat is applied to the reservoir of the Yarega oilfield. Activa-tion factors: oil viscosity reduction; separation of dissolved gas from oil; tempera-ture expansion of free gas. The current energy state of the reservoir makes it possi-ble to use the hydrodynamic model without taking into account the dissolved gas. Problems in numerical modeling are revealed. These problems are related to the quality of the source information. The authors have developed recommendations for eliminating problems.
