“…There has been several studies reported by researchers over the globe where the potential of geothermal energy generation from depleted wells have been investigated experimentally and theoretically [1][2][3][4][5][6][7][8][9][10][11][12][13]. These studies have demonstrated the potential as well as the readiness level of the technologies needed for utilization of geothermal energy from depleted wells.…”

“…Cui et al (2017) and Bu et al (2012) proposed a method for geothermal exploitation in order to calculate the heat mining rate and the relationship between the geothermal water and heat production. With respect geothermal power generation, Cheng et al (2014) analysed the heat production from geothermal water flows using heat exchangers. Aliyu and Chen (2017) applied an approach for the long-term development of geothermal heating production.…”

Rapid urbanization has resulted in severe demands on water, heat and energy resources, which threaten the sustainability of the urban economy and environment. Geothermal energy is one of the cleanest sources of energy, and it plays an important role in the sustainability of the regional economy and environment. This paper employs the vector autoregressive (VAR) model to assess the effects of water, heat and energy consumption on geothermal adoption and the interactions among these factors. Beijing is chosen as a case study to investigate the water-heat-energy nexus and examination of the relationship between geothermal adoption and the regional economy. The results reveal that water consumption has mainly affected geothermal adoption. Water consumption and energy consumption have negative effects on geothermal adoption, while the centralized heat supply has a positive effect on geothermal adoption. This paper also adopts a gear model and coupling coordination degrees to investigate the relationship between geothermal adoption and the regional economy. The rates of geothermal adoption and the regional economy vary, but they are in a good state of coupling coordination. In addition, the coupling coordination of geothermal adoption and the regional economy has the potential to improve.

“…Various fluids except water were assessed (e.g., CO 2 and organic working media) [23][24][25][26][27]. Cheng et al (2013 analyzed the performance of different organic fluids used as the heatcarrying medium for geothermal power generation and discussed the influence of the thermal insulation performance of tubing on the heat mining effect under the condition that R134a was used as the heat-carrying fluid [26,28,29]. Davis and Michaelides (2009) used isobutane as the heat-carrying fluid to simulate geothermal power generation from abandoned oil wells.…”

Based on the principle of wellbore self-circulation heat mining, the evaluation experiments of local wellbore self-circulation heat exchange laws and influencing factors were carried out. Water, SCCO2, R134a, and heat transfer oil were screened as the heat-carrying fluids. The heat exchange laws and heat mining capacity of these four heat carrying fluids were analyzed and compared, and their heat mining rates at the field scale were estimated using the similarity criterion method according to the experimental results. The results show that R134a and heat transfer oil can obtain the largest outlet temperature and the largest heat loss ratio, while the water can achieve a higher heat mining rate and a larger convective heat transfer coefficient than the other three fluids. The heat mining capacity of CO2 is significantly affected by the injection pressure. It is necessary to optimize the injection pressure larger than critical point to achieve the best heat mining performance. When the water is selected as the heat-carrying fluid, the heat mining rate can reach more than 1 MW if a horizontal wellbore with a length of 2000 m is applied for wellbore self-circulation at the field scale.
