Geothermal energy potential of Tulsishyam thermal springs of Gujarat, India

Singh, Hemant Kumar and Thankappan, Aswathi and Mohite, Poonam and Sinha, Satish Kumar and Chandrasekharam, Dornadula and Chandrasekhar, Trupti (2018) Geothermal energy potential of Tulsishyam thermal springs of Gujarat, India. Arabian Journal of Geosciences, 11 (6 - Article 137). ISSN 1866-7511


Tulsishyam thermal springs are located in the Saurashtra region of Gujarat, India with discharge temperatures varying from 39 to 42 °C. The pH of these thermal springs varies from 7.1 to 7.4, indicating neutral character. Though these thermal springs propagate through the near surface layer of Deccan basalt, detailed geochemical analysis of the thermal waters using Piper diagram suggests that the water is interacting with the granitic basement rock. Silica and cation geothermometry estimates have reservoir temperature in the range of 138 to 207 °C categorizing it into a low to moderate enthalpy geothermal system. Furthermore, the area has high heat flow values of 53–90 mW/m2 because of shallow Moho depth. The prevailing conditions suggest that the geothermal energy can potentially be exploited through an enhanced geothermal system (EGS). The study also indicates different mineral phases that may precipitate out of water during exploitation of geothermal energy and it should be taken into account while designing an EGS for the area. © 2018, Saudi Society for Geosciences.
