Reverse-time migration (RTM) provides superior images in areas where there are steep salt flanks or other complex geologic structures. However, the high cost of running RTM with regard to memory...

We present a case study of anisotropic model building and the resulting accuracy of event placement and improved image quality. Approximately 660 OCS blocks of the MC Revival survey located in...

Subsalt wave-equation based migration (WEM) scan is an effective way for subsalt velocity updating, and has become an industry standard practice; however, the cost of generating migration scan is...

Compared to surface seismic, the increased complexity associated with seafloor seismic data (OBC) requires considerable attention to details if a noise-free and well imaged dataset is to be produced....

The goal of repeat imaging (detailed studies of prospects as new information is available) using PSDM is to generate new locations for both development and exploration targets. We present two case...

3-D prestack depth migration is the most time consuming part in velocity model building. To minimize the required iteration of depth migration, we first perform a demigration to the pick residual...

Wave equation (or wave field extrapolation) techniques have been used in industry for the past few years, with the purpose to improve the accuracy of 3D depth imaging over the conventional Kirchhoff...
