Natural gas is one of the most reliable and general energy sources globally, which their reservoirs always have high pressures. Nowadays, due to the production and supply of a variety of turbine expansions, it is possible to generate power from natural gas extraction. In this research, by considering the operational conditions and exploitation data, the possibility and advantage of using turbo-expander in gas extraction process are explored. Based on the results, 0.26-1.1 MW of power can be generated from each production well using the pressure drop in the turbo-expander with the flow ranges between 0.5-2.0 million STD_m3/d. The power generation capacity due to natural gas conditions may be associated with the production of gas condensates which has also been studied in this research.
