We perform geomorphic, elevation-related and gravity studies from the three petroliferous sedimentary basins in western Rajasthan (India)-Bikaner-Nagaur, Jaisalmer and Barmer basins. Using geomorphic studies, we interpret that watersheds 1, 3 (Bikaner-Nagaur basin), 4 (Jaisalmer basin) and 1 and 3–5 (Barmer basin), to be tectonically very active at present. The elevation-related and gravity studies in the Bikaner-Nagaur basin shows a different uplift rates because of neotectonic faults and lineaments that pass through the region and enhance more incision of the channel. The gravity contour map has a very clear gradient of anomalies for each watershed in the Jaisalmer basin. The gravity values are high in the Barmer basin. Gravity low is noted in the Jaisalmer basin at places. Apparently, they have positive correlation between surface elevation and free air gravity magnitudes. We anticipate that the results provided in this work will assist hydrocarbon geoscientists to undertake more research.
