Abstract

Geothermal energy remains a promising renewable and sustainable resource for India, in particularly in meeting its growing energy demands and achieving its climate goals. This study was conducted in the Tattapani hot spring region of Chhattisgarh, one of India’s potential geothermal provinces. For the development of geothermal energy, a comprehensive understanding of reservoir characteristics, fluid flow and fluid properties are essential. The objective of this study is to assess the geothermal potential of the region through an integrated approach for resource exploration and exploitation. A multidisciplinary-investigations are carried out using geological, geochemical and geophysical methods to measure heat flow, characterize the subsurface at various depths, analyze fluid chemistry and source of water, and estimate reservoir temperatures. The techniques employed in this study included thermal, electrical, gravity, magnetic, seismic, geochemical and rock mechanics. This integrated approach led to the development of a preliminary subsurface model of the geothermal system, revealing key insights into the reservoir characteristics, system dynamics and fluid pathways.
