19 Page 8 of 9 Geomech. Geophys. Geo-energ. Geo-resour. (2020)6:19 temperature of about 150 °C (Naccache and O’Cal- laghan 2011). The production well may produce light oil, combust gases, and steam. These combust gases and steam are reinjected into the reservoir (Naccache and O’Callaghan 2011). ONGC applied ISC at Balol and Santhal heavy oil fields in 1997, which increased oil production from 6–15% to 39–45% (Naccache and O’Callaghan 2011). Since combust gases and steam produced by ISC process have a sufficient temperature about 150 °C, these fluids can be classified into the low enthalpy fluid. Therefore, before reinjecting the fluid into the formation, the heat energy can be extracted by ORC for generating geothermal power (Fig. 4). Therefore, with the installation of the ORC geothermal power plant on such site can help to reduce CO2 to the environment. 6 CO2 can be reduced by using oil field Many hydrocarbon reservoirs are usually associated with high temperature, ranging from 150 to 250 °C (Junrong et al. 2015). Moreover, exploitation of these oil filed for geothermal energy will help to reduce CO2 emission to the environment. It is estimated that a geothermal power plant having power generation capacity of 1 MWe can reduce 6000 metric tons of CO2 emission per year (Sanyal and Butler 2010). Thus, utilization of some small and medium size oilfields for geothermal resource can produce thou- sands of MW electricity and therefore, have huge potential to reduce CO2 emissions. 7 Conclusions Several abandoned oil/gas wells are present in differ- ent oilfields of India. These wells can be converted into geothermal wells to extract available heat energy in the subsurface. With this transformation, drilling cost can be saved or reduced for geothermal resource development. It also reduces the safety risk while drilling. Indian oilfields have the potential for geother- mal resource development. 1. Assam basin has the reservoir temperature ranges from 60° to 116 °C and with an average heat flow 2 2. KG basin has encountered the reservoir temper- ature of 205 °C and have high heat flow value 63–104 mW/m2. 3. Cambay basin bottom hole temperature varies from 49° to 214 °C also have the high heat flow value 75–93 mW/m2. 4. In Cauvery basin, measured bottom hole temper- ature ranges from 90 to 120 °C with the cratonic heat flow on the basin margin is 37–55 mW/m2. From geothermal perspective, Indian oilfields can be characterized as low to moderate enthalpy systems. These oilfields are suitable for exploitation of geother- mal resource and geothermal power can be generated using the ORC cycle power plant. Geothermal power can also be generated from a combination of downhole heat exchanger and in situ combustion of hydrocar- bons with ORC geothermal power plant. Thus, there is a huge potential of utilizing existing wells in the oilfields for green power development economically.
