“…In this case, according to Barelli et al [20], similar conditions of the fluid can be estimated, but a volume of 80 km 3 can be roughly estimated, so that a maximum level of 1200 MW can be estimated. But it is quite clear that such a simplified approach caused an overestimation of the real potential of the reservoirs.…”

Abstract. The paper analyze the problem of the estimation of the potential of geothermal reservoirs with the objective of sizing of geothermal power plants in order to reach the goal of a correct matching of renewability and economic related issues. After an analysis of the typical approaches based on the First Order Method diffused in the literature since the late 70s and of the uncertainties connected with the use of simplified approaches, that have determined general overestimation of the geothermal energy stored in the reservoirs and of the size of the plants connected to various geothermal fields, the authors discuss about possible improvements based on the combination of theoretical simplified approaches with experimental data of heat flow, taking into account not only the energy stored, but also the possibility of producing a recharge.

“…But this approach has determined several problems, [3,4]. In recent times the concept of renewability has been improved introducing the idea of sustainability: this concept include the idea of using geothermal resources using some compensative actions, like cultivation strategies and reinjection.…”

“…Geothermal power is regarded as the only renewable energy source that is entirely independent of seasonal or climatic changes, thus allowing it to achieve high capacity factors in excess of 90% [313,314]. In 2005, 9,084 GW of geothermal power generated 56,951 GWh of electricity [315], which is equivalent to an average capacity factor of 71%.…”

“…The cost of the latter are more variable (10%-50% of total cost) because different requirements in low-and high-temperature geothermal fields, and also more uncertain because reliable estimates of the generation capacity of a geothermal reservoir can only be obtained once the reservoir has been tested under production. Subsurface cost can be assumed as increasing linearly with the number of wells [314].…”

“…This suggests a step-wise development of geothermal resources, with system expansion being undertaken in 20-30 MW units, as practised in Iceland. However, such a strategy also implies delays of up to 6 years between the drilling investment, and the financial returns from power production, so that conflicting goals must be managed [314].…”

Electricity is perhaps the most versatile energy carrier in modern economies, and it is therefore fundamentally linked to human and economic development. Electricity growth has outpaced that of any other fuel, leading to ever-increasing shares in the overall mix. This trend is expected to continue throughout the following decades, as largeespecially rural-segments of the world population in developing countries start to climb the "energy ladder" and become connected to power grids. Electricity therefore deserves particular attention with regard to its contribution to global greenhouse gas emissions, which is reflected in the ongoing development of low-carbon technologies for power generation. The focus of this updated review of electricity-generating technologies is twofold: (a) to provide more technical information than is usually found in global assessments on critical technical aspects, such as variability of wind power, and (b) to capture the most recent findings from the international literature. This report covers eight technologies. Seven of these are generating technologies: hydro-, nuclear, wind, photovoltaic, concentrating solar, geothermal and biomass power. The remaining technology is carbon capture and storage. This selection is fairly representative for technologies that are important in terms of their potential capacity to contribute to a lowcarbon world economy.

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.
