Summary I present a method for computing reflection angle gathers using time-shift extended least-squares reverse-time migration. The method is aimed at producing image gathers that can be interpreted in terms of angle-dependent reflection coefficien

We present a method for automatically obtaining a detailed, accurate representation of a top-salt velocity model contrast, starting from a crude initial top-salt interpretation. The method is based on the analysis of time-shift gathers obtained in a

A tomographic inversion method is presented that uses kinematic information in the form of zero-offset traveltimes and kinematic wavefield attributes (first and second spatial traveltime derivatives) to determine smooth, laterally inhomogeneous 3D su

In this paper I present a pragmatic and efficient approach for computing full-volume reflection angle/azimuth gathers using reverse-time migration. The method is based on the post-imaging analysis of event slopes in local horizontal subsurface-offset

Data quality is an important issue in seismic data processing. In this context ocean bottom nodes are particularly interesting. 4-component nodes are plugged in the sea bottom by a remote operating vehicle and record the seismic vector wave field. As
