Summary Data driven Velocity Model Building (VMB) based on Full Waveform Inversion requires very broad band, especially low frequnecy data content to overcome the cycle skipping problem. In this paper we demonstrate how the Joint Migration Inversion

The common-reflection-surface (CRS) technique provides an effective workflow for seismic data preparation and imaging in large areas of regional studies. In a case study from the North Sea, the multi-parameter stacking technique is used to combine an

Wide azimuth (WAZ) marine seismic data commonly provide an enhanced but varying coverage in azimuth-offset domain, which decreases towards crossline azimuths and near-offsets. The variable offset-azimuth illumination of WAZ data is commonly exploited

Noise suppression and signal enhancement prior to prestack depth migration (PreSDM) may significantly increase the resolution of the depth image, and the effectiveness of the PreSDM workflow. The Common-Reflection-Surface (CRS) technique was previous

The structural resolution of complex subsurface geology generally requires advanced prestack depth migration based on wave-equation algorithms. The full benefit of these costly algorithms, however, may be missed in case of irregular spatial data samp

Near-surface mute zones hamper the derivation of near-surface velocities, and degrade the near-surface image. Operator noise at mute edges may obscure the near-surface image after migration. In order to avoid such problems an interpolation method for

A case study for 3D seismic land data from Mexico uses high-resolution CRS attribute volumes for improving the imaging and model buildung in salt geology. Initial CRS time processing provides both, an initial outline of the salt body, and general inf

An accurate delineation of salt bodies is essential for the quality of model-based seismic imaging. This depth imaging study for 3D land data from Mexico demonstrates that high-resolution image and attribute volumes from Common-Reflection-Surface (CR
