3D Converted-Wave Processing Over the Valhall Field

An investigation of statics correction methods for 3D PS-wave seismic reflection

“…In recent years there has been a growing trend towards applying this technique to 3D targets (e.g. Simin et al, 1996;Hanson et al, 1999, Brzostowski et al, 1999. Often, PS-wave reflection has been restricted to situations where conventional P-wave methods have encountered problems, such as imaging structures in the presence of gas (eg.…”

A practical approach to P‐SV prestack time migration and velocity analysis for transverse isotropy

“…Advanced P-SV processing techniques now exist to produce credible isotropic images of C-waves using multicomponent OBS recordings in complex areas Zhu e t al., 1999;O'Brien et al, 1999;Barkved et al, 1999;Brzostowski et al, 1999;Yuan et al, 1999. Further complications often arise due to the wide occurence of vertical transverse isotropy VTI in marine sediments.…”
