Abstract: An important contribution of geosciences to the renewable energy production portfolio is the exploration and utilization of geothermal resources. Geological and geophysical methods are the two most important branches in geothermal exploration. All geophysical activities are very much contributing to identify geothermal prospect. The geophysical activities like Magnetotelluric, Gravity, Magnetic and Seismic methods are used to delineate geothermal prospect in this paper a case study from Dholera, Gujarat has been taken to find out the prospect of geothermal reservoir in application with the refraction seismic survey. A finite study modelling of seismic wave propagation was conducted to determine the layers of the earth which are consisting zones of geothermal energy. This case study is basically dependent on seismic API survey i.e. Seismic Acquisition, Processing and Interpretation has been conducted here. This seismic survey has been deployed along four profiles in the area identified by previous studies conducted in the area including MT survey. Seismic data are processed to find the shallow subsurface features and tomograms. The tomograms obtained from the seismic survey are integrated with SP and Resistivity well log data, which were carried out in a nearby location offset to the seismic profiles. The integration helped to get a clearer picture of the subsurface.
