Increased industry exploration interest in the Tarakan Basin, offshore East Kalimantan, Indonesia, has stimulated a need for 3D seismic data that incorporates recent advances in imaging and velocity...

The structural style of the African Atlantic margin shows significant differences between the passive rifted Northwest African Atlantic Margin (offshore Senegal, Gambia, Guinea Bissau and Guinea) and...

The Baffin Bay area offshore northwest Greenland represents a vast frontier exploration province. The aim of this work has been to create a new structural elements map for the region and assess the...

One of the fundamental challenges for anisotropic tomography is the trade-off between the inverted velocity correction and the anisotropic parameters correction. The studies in this paper find that...

Due to the accuracy of the Reverse Time Migration (RTM) algorithm, RTM angle gathers show more coherent and correct moveout subsalt events than Kirchhoff offset gathers, potentially providing a more...

As an alternative to the conventional high-resolution Radon transform, we propose a time-domain approach to transform a gather of pre-stack seismic data into a gather of highly-resolved traces in the...

The implementation and production application of fast Reverse Time Migration (RTM) algorithms, especially for Tilted Transverse Isotropic (TTI) medium, is critical if the seismic industry is to...

Tilted Transverse Isotropic (TTI) Reverse Time Migration (RTM) is routinely used for depth velocity model building. To improve the efficiency of RTM we have developed an approach called...

We present an advanced velocity model building and imaging methodology that resulted in significant enhancements in defining the salt flanks with overhangs and subsalt structures. The key...

The Hoop Fault complex in the Southwestern Barents Sea presents an imaging challenge to accurately model the sharp velocity contrast across a major fault boundary. Improperly accounting for this...
