Abstract

Seismic exploration in compressed anticlines of fold belt areas is a challenge worldwide. Banskandi anticline of Cachar Fold Belt was covered by Wide Azimuthal Seismic Survey. The data like conventional seismic data has low signal-to-noise ratio as we approach the anticline due to subsurface conditions as well as shadow zone created around the limb of anticlines. An integrated approach to the study of the fault patterns and seismic attributes was carried out on a part seismic data covering approximately 32 Km2 of southern part of the Banskandi Field. This study aimed at improving the visualization of faults in the study area using three different filters: the dip-steered median filter to remove random noise and increase the lateral continuity of reflections, the dip-steered diffusion filter to sharpen the faults and the fault-enhancement filter used to enhance the discontinuities of the reflections.
