Mercury Computer Systems Powers CGG's Seismic Processing Solution

3/16/2005 - Mercury Computer Systems, Inc. announced that Compagnie Generale de Geophysique (CGG) selected Open Inventor(R) from Mercury and VolumeViz(TM) LDM (large data management) visualization components, to develop the latest version of its Geocluster(TM) seismic processing software.

CGG, a principal supplier of geophysical products and services to the worldwide oil and gas industry, has integrated the VolumeViz LDM technology into the latest release of Geocluster, its industry-leading seismic processing and interpretation software application. With the incorporation of VolumeViz LDM technology, Geocluster can address the growing need of geophysicists for greater autonomy to run increasingly compute-intensive applications involving the visualization of large data volumes and detailed graphic interpretation.

"One of the most important shifts currently taking place in seismic processing, visualization and interpretation is in the area of interaction," said Pascal Rosset, CGG's vice president of Research, Development & Industrialization for Data Processing & Reservoir Services. "The VolumeViz LDM software from Mercury is a key enabling technology for our application developers working on this shift -- it provides the latest volume-rendering visualization technology in terms of scalability, flexibility and performance, even on desktop platforms. It is very exciting because it enables us to continue bringing our Geocluster end users ever-increasing levels of interaction with continuously growing seismic data volumes."

Today CGG raises the standard by delivering the most cost-effective, high- performance processing services and solutions available to the worldwide oil and gas industry. Mercury technology is integrated as a standard in the geophysicist's desktop and interpretation workstation and will contribute to increased accuracy as well as facilitate decision-making. CGG continues to be closely involved in enhancing the specifications of Open Inventor from Mercury and VolumeViz LDM software.

"Mercury is very proud to have been selected by CGG to provide visualization technologies participating in the interpretation of ever larger seismic data sets," said Jean Bernard Cazeaux, vice president of Geosciences, Imaging and Visualization Solutions, Mercury Computer Systems. "Our VolumeViz LDM technology allows unprecedented access to extremely large data sets, and at the same time provides a remarkably interactive user experience. The user perceives that any portion of the volume can be displayed immediately, the volume can be navigated smoothly at all times, slices and probes are responsive at all times, and image quality is automatically managed to the best possible level."

About Geocluster
With Geocluster, CGG runs parallel cluster computing power to process large-volume modern datasets through intensive workflows (e.g., Pre-SDM) and leverages on the latest generation of PCs. Geocluster runs on major UNIX platforms as well as on economical Intel servers using the Linux operating system. Geocluster is designed to run in true parallel mode on several UNIX and Linux systems. New technologies are incorporated in Geocluster as a network-wide distributed processing and distributed operating environment to ensure optimum workload balancing and flexible hardware management.

About VolumeViz LDM
VolumeViz LDM from Mercury provides a complete solution for rendering volume data using a variety of techniques including slices, skins, direct volume rendering, and much more. VolumeViz LDM takes this visualization capability even further by allowing you to view huge amounts of data on systems ranging from laptops to fully immersive virtual environments.

Today many volume data sets, for example seismic data, commonly exceed 10's or even 100's of gigabytes. The VolumeViz LDM solution is an innovative hierarchical, multi-resolution data manager allowing the rendering of extremely large data sets with reliable interactive navigation even on relatively low-end machines. For best results, the data is pre-processed to create a hierarchy of lower-resolution (sub sampled) "bricks." The bricks at each higher level represent a larger portion of the total volume at a lower resolution. So overall, the top level brick contains a low resolution "overview" of the entire volume, and the lowest level bricks contain the full- resolution data.
