Studies on geothermal power generation using abandoned oil wells

Cheng, Wen-Long; Li, Tong-Tong; Nian, Yong-Le; Wang, … - In: Energy 59 (2013) C, pp. 248-254

In this paper, abandoned “dry hole” oil wells are simulated as a source of geothermal power for generating electricity. Isobutane is chosen as the working fluid. It is heated by the geothermal energy from geologic formation and drives the turbine to generate electricity. A model based on...
