The Rajasthan basin is positioned in the western part of India's western part. Through a comparative quantitative interpretation study with the support of two vintage seismic surveys, the study was carried out in two regions in the Jaisalmer sub-basin. Two nearby areas in the Jaisalmer sub-basin, where Ghotaru has seen few hydrocarbon finds; however, no such finds were made in the Bandha area. The current research concentrated on the Jaisalmer limestone formation in the Jurassic period. Structural deformation was a key factor in the morphology of limestone facies' rock properties. Based on P-impedance values, a post-stack seismic inversion was carried out to capture the rock property shifts in the limestone reservoir. In comparison to the Bandha region from this report, the Ghotaru area showed high P-impedance development. A probable hydrocarbon-bearing reservoir unit in the Ghotaru Formation of the High Impedance limestone lithofacies is a probable hydrocarbon-bearing reservoir unit.
