Some design issues for 3C-3D OBC seismic data
Donald C. Lawton, Brian H. Hoffe
Depth-specific conversion point (DSCP) mapping is superior to asymptotic conversion point (ACP) mapping for 3C-3D seismic survey design. P-S fold patterns at target levels depend on Vp/Vs, and in the case of ocean bottom cable (OBC) data, also on water depth. These issues are illustrated in a simple design example.
