| Abstract | There is a good potential for developing geothermal energy in India. Tapping of this ecologically clean and environmentally friendly resource requires a good understanding of deep structures below geothermally anomalous regions. Most of these regions comprise zones of high electrical conductivity due to the presence of hot fluids and associated minerals. The most suitable geophysical methods to delineate these zones are deep electrical and magneto telluric (MT) methods. In India, deep electrical and MT investigations for geothermal energy have been conducted in three different geological settings, namely: Konkan Geothermal Province along the western coast, Tatapani Hot Spring Area in the Narmada-Son Lineament Zone, and Puga Geothermal Area, Ladakh, Jammu and Kashmir.† Encouraged by the results of these studies, other areas in Himalayan belt region and also Jharkhand region are being taken up for detailed studies. A brief description of the salient results from these studies is followed by the detailed modeling results from the Puga Geothermal Area. 1-D and 2-D analysis of 35 MT soundings from this area reveal shallow (< 400 m) and deep (2km) conductive zones related to the geothermal reservoir. Multi-profile modeling and dimensionality indicators suggest that the reservoir is a 3-dimensional feature with sharp variations towards east and west.† Govt. of India, intends to develop it for power supply in Ladakh region. |
