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 ...

Commonly fitted by an ellipse, AVOAz is actually better approximated using limaçons. The article begins by reviewing the properties of the original limaçon, then explains how they can apply to AVOAz and finally illustrates how limaçons can help with the interpretation of anisotropy on ...

An overview of the general oil exploration landscape in Norway with a description of the Horda survey, concentrating on the acquisition, but including references to the complete integrated geoscience package that will eventually be delivered

In ocean bottom acquisition, receiver side deghosting is normally done by summing together the hydrophone P and geophone Z data. A prerequisite for this method to work effectively is the precise calibration of geophones to hydrophones, so as to compensate for the differences in ...
