In Pakistan, round about 1000 oil and Gas exploratory wells have been drilled having depth ranging from 230 m to +6400 m. More than 60 percent wells have been abandoned or dry wells. In spite of all exploratory effort we are not able to overcome the energy need of the country. Present study looks forward to reutilizing these abandoned wells by using subsurface data related to thermal characteristics of rock sequence. Present study shows heartening geothermal gradient exception in lower Indus Basin coupled with buried fossil-fail-rift basement structure. Aeromagnetic survey has also disclosed significant prediction for the “hot dry rock” geothermal energy in Kharan- Panjgur tectonic depression in western part of the Pakistan. Literature review shows for electricity production hot dry rock (HDR) geothermal environment offers massive potential. These resources are mostly much deeper than the hydrothermal resources. Hot dry rock energy comes from moderately water-free hot rock found at a depth of 4,000 meters or more below the earth surface. In contrast to a geothermal field in one of the tectonic/volcanic anomalies, the HDR system depends on the artificial simulation of tight formations by hydraulic fracturing to create underground heat exchanger. Fluid circulated in closed circuit mode where as reservoir pressure is managed by balanced production and injection rates in multiple well arrays. Current study shows the matchless application of collection data of Oil and Gas exploratory wells to develop renewable and sustainable energy operation in Pakistan.
