The data driven 3D true azimuth Common Focusing Point (CFP) data regularization technique is a multi-dimensional data regularization tool. It can be used as a general tool to merge multiple surveys...

We propose a time-domain approach to transform a gather of pre-stack seismic data into an ensemble of highlyresolved traces in the transformed domain. Using a range of various velocity functions in a...

Extensive sequences of flood basalts dominate the northwest European Atlantic margin. The basalt flows absorb and scatter the higher frequencies present in any source wavelet through intrinsic and...

Anelastic properties of the earth cause frequency dependent energy attenuation and phase distortion in seismic wave propagation. It is preferred that these unwanted effects be corrected in a prestack...

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...
