Abstract

The main methods of geothermal energy extraction are characterized. Given the significant number of depleted natural hydrocarbon fields, the issue of reusing previously drilled wells is becoming increasingly relevant. Examples of the implementation of geothermal energy extraction technologies at depleted natural hydrocarbon fields are analyzed. It is shown that the main risk and capital investment in the implementation of geothermal energy extraction technologies is the drilling of new wells. Practical experience in implementing geothermal energy extraction technologies has shown that approximately 25 GWh of electricity can be produced from a single well with an installed capacity of 500 kW over 10 years. To assess the impact of technological factors, namely the influence of injection/production flow rates, the distance between injection and production wells, and the temperature of the injected water on the period of geothermal energy extraction, the software complexes Petrel and Eclipse were used. The research was conducted using a synthetic model of an aquifer. The results of studies on the impact of the investigated parameters on the period of geothermal energy production were analyzed, which were evaluated by determining the temperature of the produced water from the investigated parameter. It was found that with an increase in injection/production flow rates, the period of geothermal energy extraction decreases. It was also found that with an increase in the distance between the injection and production wells, the period of geothermal energy extraction increases. Increasing the temperature of the injected water ensures an increase in the period of geothermal energy extraction. Research on the impact of various technological factors on the efficiency of geothermal energy extraction makes it possible to optimize the processes that ensure the production of this type of energy
