ABSTRACT

2D forward numerical seismic modeling of a complex geology structure was used in this experiment to optimize the acquisition parameters and to aid in the seismic interpretation. Synthetic seismic data were acquired for a numerical model of a fault-fold structure encountered in North Eastern British Columbia. These synthetic shot gathers are used to investigate which migration algorithms would produce the best images in such complex environments. Results have shown that the pre-stack depth migration from the topography with the known velocity model have yielded the optimum migrated image. Acoustic and elastic numerical modeling techniques were used to simulate waves propagating in the complex medium, and the most difficult structural styles to image were investigated.
