“…By adopting optimization, the costs of abandonment can be minimized each year, from USD 76K on 2015 to USD 52K on 2017. In another paper, Prasetya et al 100 estimated the cost of well abandonment in Block “G,” South Sumatra to be around USD 60 000 to USD 1 500 000 depending upon the well depth and integrity issue (good, moderate, and poor). Ojukwu 101 estimated the cost of onshore well abandonment in Nigeria will be around 1 million per well, not including the cost of facility decommissioning and removal, field location restoration, and site reclamation.…”

Summary Retrofitting depleted oil wells to extract geothermal energy is considered as one of the promising proposals to extend the overall economic life of oil and gas well. For successful implementation of this initiative, a comprehensive overview covering all aspects of geothermal energy extraction from abandoned oil well should be taken into account including technical, economic considerations as well as regulations and policies of respective local governments. Unfortunately, most reported studies have been focused only on one or two aspects, primarily on technical and economic aspects. Little or no study has focused on the policy sector. Moreover, these findings have been scattered, creating difficulties to extract essential information and dragging further development of the technology. This paper is therefore prepared with the objective to provide a comprehensive overview on the geothermal energy extraction from abandoned oil well, technical challenges in its implementation, economical consideration on the conversion of the well and government policy on energy especially geothermal energy and regulation on the utilization of abandoned oil well. To achieve this objective, extensive literature reviews are conducted with more attention given to recent studies on the field. Challenges on the development of this technology are discussed from technical, economic, and policy perspectives. Based on the identified challenges, required research and development as well as necessary policies for further advancement of this technology are outlined and discussed. By providing this comprehensive information, this review paper may serve as a good foundation and guidelines on the conversion of abandoned oil wells into geothermal energy wells.
