Abstract

Processing of 2D long offset Seismic Reflection data for sub basalt Imaging still remains a challenge for the Processing Geophysicists. So far there is no commercial processing solution for meaningful imaging below basalt. Time domain processing has its limitations to process reflection events which are hyperbolic in nature. With careful analysis of suitably pre-conditioned long offset dataset and detailed velocity analysis, imaging could be improved to map the base of basalt, leaving scope for further improvement in the sub basalt section
