TGS imaging releases PRIMA™ 7.0

07 March 2005

Houston, Texas (March 7, 2005) - TGS Imaging, the seismic data processing division of TGS-NOPEC Geophysical company, has released a new version of the PRIMA pre-stack interpretation and analysis software. Release highlights for version 7.0 include new interpretation tools and features, functionality improvements, well log overlay capabilities and enhanced workflow integration.

The release adds a new "Interactive Surface Viewer by Offset" tool for improved gather attribute displays. Gather attributes can now also be submitted as a batch job to optimize computational delays. With this version, PRIMA has the ability to display and overlay well paths and curves in certain modules. Several other enhancements were made to improve ease of use and increase task efficiency.

PRIMA 7.0 has been upgraded to be compliant with OpenSpirit 2.7, to allow for greater import/export abilities, including well logs and seismic slice volumes. The software is also available with the Linux operating system, thereby greatly expanding the number of hardware platform options, and reducing total ownership costs.
