Parameterization lies at the center of anisotropic full-waveform inversion (FWI) with multiparameter updates. This is because FWI aims to update the long and short wavelengths of the perturbations. Recently, there has been an intensive effort to determine the optimal parameterization, centering the fundamental discussion ...

Initial imaging results are deeper and clearer than have been seen in this area before, with enhanced imaging of the Triassic to Lower Cretaceous reservoir units. In addition to demonstrating that there is at least 20km of sediment in this area, clear faulting and ...

We demonstrate how we unlocked the potential of one of the last underexplored regions of the South Atlantic margin through smart seismic acquisition, processing technology and close collaboration.

Recently there has been renewed interest in the hydrocarbon potential of the Perth Basin in Western Australia. Recent discoveries of gas have shown that there is a working hydrocarbon system within at least the northern and central parts of the basin. In most parts ...

The deepwater Gabon South Salt basin represents one of the last underexplored regions of the West African continental margin. A new 25,000-sq km (9,653-sq mi) broadband 3D seismic survey was recently acquired in the basin as part of an integrated eoscience program to support ...

Gulf of Mexico (GOM) subsalt imaging often suffers from poor illumination due to salt-related wavefield distortion, even with full-azimuth (FAZ) acquisition. In order to image the weakly illuminated subsalt plays, isolating the signal from the noise is a crucial component of many depth imaging ...

This case study highlights how the application of an optimized hydraulic fracture stimulation plan, by honoring lateral well geological heterogeneities measured by RoqSCAN, improved completion efficiency and well production within the Cleveland Sandstone formation, Oklahoma, USA.

The quality of the seismic data you record depends on the quality of the energy generated by the source, how it interacts with the subsurface and the ability to record all the effects of those interactions. To obtain the required response from the reservoir ...

In this article, we focus on variable-depth streamer acquisition and propose a full broadband processing solution that involves three important components: (a) 3D deghosting; (b) Q estimation using Q-Tomography; (c) Q application via Q pre-stack depth migration (Q-PSDM).
