Global increases in energy demand and fossil fuel dependency hamper efforts to reduce greenhouse gas emissions. Due to its availability, base-load production profile, and climactic independence, geothermal resources are a leading candidate to supplement rising energy demand with lower emissions. Despite those advantages, geothermal energy development is limited for different reasons, including subsurface exploration risk and high upfront capital costs for drilling and facilities construction. However, similarities in infrastructure and operations between the oil and gas industry and the geothermal industry are an exciting option to optimize costs and development when exploiting geothermal resources. In this sense, in this review recent advances and applications of geothermal power systems in the oil and gas industry are presented. These applications include the use of geothermal resources through abandoned wells, active wells and paired thermal enhanced oil recovery processes with inj
