CGG has launched its four component seismic processing package VectorVista 4C. Four component seismics can help in the exploration of awkward geometries – such as the flanks of some North Sea oilfields – where conventional seismics fails to produce a clear image.
VectorVista is the latest member of the Vista family of seismic processing services and software offered by CGG. Other members include ChronoVista for time processing, GeoVista for depth imaging, and StrataVista for reservoir characterization.
VectorVista Project Manager Pierre-Yves Granger said, “Until now 4C has been held back by the lack of interpretation tools. We have put over thirty years of multi-component processing experience into VectorVista which now integrates converted waves into the interpretation workflow and will ultimately facilitate the instrumented oilfield.”
An industry consortium comprising Norsk Hydro, ENI-AGIP and UK consultants Anitek is building the VectorVista processing workstation. VectorVista can display ‘squeezed’ PS sections and perform a range of PP/PS ratio computations. Well log data management is built in for VP/VS velocity modeling and AVO plots on synthetic offset displays.
The platform-independent Java-based toolkit, J/GeoToolkit from INT is used for the graphical user interface (GUI). CGG is seeking participation from other companies in the Vector Vista 4C consortium. More from www.cgg.com.
