Paper presented at the 2005 SEG Annual Meeting, November 6–11, 2005
Paper Number: SEG-2005-1989
... ABSTRACT The generalized screen propagator (GSP) is a one-way wave equation based wide-angle propagator. The dual domain implementation of GSP migration provides a fast and accurate 3-D wave field extrapolation and produces high-resolution and high-fidelity subsalt images. This migration...

... uses ray-based methods, the recently developed wave equation based method provides a more powerful and more accurate tool to provide these calculations. GSP migration on a Hickory dataset The seismic data used to image Hickory Field was acquired by PGS for Diamond Geophysical using a two boat system...

Paper presented at the 2002 SEG Annual Meeting, October 6–11, 2002
Paper Number: SEG-2002-1316
... Summary Generalized screen propagator (GSP) is a wave-equation based, wide-angle wavefield continuation operator and has been applied to both poststack and prestack depth migrations for imaging complex structures. Offset domain GSP migration provides a fast and accurate 3-D wavefield...
