Abstract

In the present study, three volumes of seismic were merged and used as one volume for depth imaging. One of the major challenges that interpreters were facing, while working on the earlier PSTM data, was in mapping of lateral continuity and fault extent at Nagod, Kaimur, Rohtas, Mohana, Jardepahar, Kajrahat, and Basement level. With an aim to delineate these formation tops and proper imaging of faults in the study area, local angle domain imaging technique was used for depth imaging, with grid tomography to iteratively update the interval velocity volume. The subsurface imaging resulted into better reflection continuity as well as discontinuity at the required formation levels.
