Abstract

The exploration strategy in the volcanic regime in the worldwide basins is becoming gradually challenging due to criticality of the sub-surface geology. The challenge takes more critical mode in Kutch and Kutch Saurashtra basin of western offshore India. The reasons being the presence of the basalt, thickness of basalt, the morphology of basalt, presence of intrusive below basalt that not only puzzle the geoscientists but also limits the seismic methods to receive echoes from below. The very limited number of wells, exact identification of Horizons, its continuity and S/N ratio of data within and below thick basalt limits velocity model building through reflection Tomography
