Extended seismic bandwidths provided by broadband acquisitions (BroadSeis), improved illumination from wide-azimuth (WAZ) configurations and high spatial resolution made possible by dense acquisition techniques are all new technologies producing visually compelling imaging and reservoir results. In addition, application of the latest reservoir characterization tools and workflows on these data are bringing greater insight into the inner workings of petroleum reservoirs.

A case study of the acquisition and background to the integrated multi-client geoscience project over the Gabon South basin.The deepwater area of the Gabon South basin is one of the last underexplored areas of the West Africa Atlantic Margin. CGG is acquiring and imaging a large broadband, multi-client 3D survey, covering over 25,000 km2 in this area, which will form the cornerstone of a major, integrated G&G study of the region.

Successful development of known fields requires high-quality seismic data in order to accurately delineate the reservoir through processes such as seismic inversion and reservoir characterization studies. In the new oil price regime this has become even more important as oil companies try to keep the total cost of production down while at the same time optimizing the life of the field. Tailored seismic acquisition designs with complementary imaging technology matched to the local geology provide seismic data that better meets the objectives for each reservoir.
Reverse Time Migration of Multiples: Applications and ChallengesReverse Time Migration of Multiples: Applications and Challenges

Marine seismic acquisitions record both primary and multiple wavefields. In a typical processing sequence, multiple energy is removed from the data before migration. However, there may be valuable information contained in the multiple wavefield. To discover this hidden information, reverse time migration of multiples (RTMM) was proposed. We evaluated the advantages of RTMM through three different real data processing projects and identified three key advantages. Additionally, we present a synthetic study of two types of crosstalk noise that hinder the full potential of RTMM as well as propose corresponding practical strategies to handle them.

The main area of hydrocarbon exploration in the Northern North Sea has been within pre- and syn-rift Jurassic sandstones. This is with the exception of chalk reservoirs in the Ekofisk field and Palaeogene sand reservoirs of the Frigg field. Now, with ignited interest in the Horda Platform, and particularly after the discovery of the Grosbeak and Skarfjell oilfields, attention has been directed towards the hydrocarbon potential within post-rift Cretaceous sands. The prospectivity of the Cretaceous sands was demonstrated more than three decades ago with the Agat discoveries.
Central North Sea: Advances in Technology with CGG's Cornerstone dataCentral North Sea: Advances in Technology with CGG's Cornerstone data

There are a number of geophysical challenges when attempting to image the sub-surface in the Central North Sea. These consist of shallow anomalies, heavy multiple contamination and sharp velocity contrasts. With a combination of broadband data and CGG?s latest processing and imaging techniques, these challenges become significantly reduced.
