The application of full-waveform inversion (FWI) to bring high resolution to the velocity model is becoming a standard approach in the velocity model-building workflow. Diving wave FWI in conjunction...

The TGS Gigante project is comprised of 188,497 km of 2D seismic data acquired in 2016 and primarily covering the offshore Mexican side of the Gulf of Mexico (Figure 1). Within the survey, 180...

By analyzing the reasons for success and failure of a given well, we can learn more about the hydrocarbon system in which the well was drilled and improve the chances of success in the future. TGS...

The massively parallel nature of Graphics Processing Units has made them an attractive platform for some computationally intensive algorithms. This article presents a method to run 3D Kirchhoff...

The Lower Zubair sand reservoirs have produced or shown oil in several but not all of the wells drilled in western and southeastern Kuwait. Evidence from the available core and log data analysis...

Conventional marine seismic data is affected by the interference from ghosts on both the source and receiver sides. The natural diversity provided by propagation directions, depth variations and...

The Angola basin is characterized by steeply dipping sediments with rapid changes in dip direction particularly in mini-basins between salt bodies. This creates difficulties in anisotropic model...

We develop an efficient scheme of illumination analysis along a target horizon. With this scheme, we can calculate the Directional Illumination (DI) from the sources and the Acquisition Dip Response...

We present a case study of the salt model building for a Gulf of Mexico area with a full azimuth (FAZ) dataset that was created by merging two orthogonal 3D wide azimuth (WAZ) surveys, the Kepler and...
