Abstract:
Traditionally, prestack depth migration (PSDM) was considered an exotic technology, applicable only for imaging "complex" geology. Offshore subsalt imaging drives the use of the most advanced PSDM technologies, like Reverse-Time depth Migration (RTM), however, given the recent resurgence of onshore exploration, we ask: can PSDM make an impact on "easy" onshore plays? We present an unconventional oil shale case study which convincingly illustrates three key reasons for (re)considering PSDM:
1) Remove false time structures caused by lateral variations in velocity. 2) Improve focusing of dipping beds and faults. 3) Improve the accuracy of seismic attributes.
