In an increasingly complex and challenging environment, CGG is building effective links between academia and industry and utilising new techniques to enhance hydrocarbon exploration success in a world where oil prices are highly volatile. In this environment there is increasing focus on risk reduction ...

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 ...

The prediction of porosity is essential for the identification of productive hydrocarbon reservoirs in oil and gas exploration. Numerous useful technologies have been developed for porosity prediction in the subsurface, such as multiple attribute analysis, kriging, and cokriging. Kriging allows us to create spatial ...

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).

In seismic processing and reservoir characterization we often need to measure relative displacements between different realizations of data. Over the years many methods have been developed utilizing different similarity measuring techniques. Such alignment or warping methods are often effective signal or image processing tools ...
