The paper gives an overview of a full 4C deblending process and its results up to migration in the case of a real 2D 4C dataset acquired offshore Malaysia. Special emphasis is put on the deblending QCs and the specificities of the deblending flow ...

Article describes application of TomoML to our 35,000 km2 Cornerstone survey in the North Sea. Also make reference to broadband deghosting, dip-constrained channel tomography and dual azimuth.

We have developed a method to jointly depth invert frequency and time domain Airborne EM data in complex topographic and geologic environments, in 2.5D and 3D. Inversion of synthetic and field data show that using AEM data sets with complimentary information (geo-steering) increases the ...

Amplitude versus Offset and Azimuth (AVOAz) Analysis can be separated into two separate parts; Amplitude versus Offset (AVO) analysis and Amplitude versus Azimuth (AVAz) analysis. Useful information about fractures and the anisotropy is obtained by just examining the AVAz. The AVAz can be described ...

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 ...

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 ...

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 ...

This study explores the predictive capability of an integrated geologic, petrologic, petrophysical and geophysical model based on detailed facies analysis of thirteen sediment cores expanded over 400 wireline log suites and 440 square miles of 3D seismic in the western Powder River Basin, Wyoming.

The economics of unconventional plays can be improved if horizontal wellbores target facies with favorable reservoir and geomechanical properties. An integrated, multi-disciplinary approach has been developed in order to reduce economic risk, facilitate improved and faster decision making and enable more efficient and effective ...
