CGG releases HampsonRussell software update

PARISCGG GeoSoftware has released HampsonRussell 10.1 (HRS 10.1), updating the geophysical interpretation and analysis software.

CGG said that HRS 10.1 introduces new methodologies to calculate the uncertainty of azimuthal analysis and display the results. It includes new capabilities for the most efficient use of computer processing threads. Automated inversion parameter tests allow users to quickly select the best values, optimize the number of runs needed for a reliable result, and potentially reduce overall inversion time.

A new feature is AVO quick modeling, in which a table of P-wave, S-wave, or density values can be entered for up to six layers. Users can then drag and drop the curves, interactively update a synthetic AVO offset or angle seismic gather display in real time, and show results as a graph.

To enhance interpretation of inversion attributes, automated analysis can now distinguish clusters of crossplot points from either well logs or seismic volumes and interactively display those cluster zones throughout the seismic volumes. In addition, colored zones from rock physics templates can now also be interactively displayed throughout seismic volumes and as geobodies in 3D.

CGG GeoSoftware also announced that it had renewed the donation of the HampsonRussell geophysical software package to the King Abdulaziz University in Jeddah, as part of CGG’s continuing cooperation agreement with the university through ARGAS, its joint venture with TAQA in Saudi Arabia.
