MediaWall Processor Aids in Search for Oil

When Petroleum Geo-Services needed to monitor its seismic acquisition data in real time on board a custom-built marine vessel, it turned to RGB Spectrum and its technology partner, Global Control Center Design, for the solution.

PGS is a technology focused oilfield service company principally involved in providing geophysical services worldwide. The company provides a broad range of geophysical and reservoir services, including data acquisition, processing, interpretation and field evaluation. With headquarters in Oslo, Norway and regional offices in London, Houston and Singapore, the company has offices in 33 different countries. PGS has unrivalled experience in seismic data acquisition, reflected in the performance and efficiency of its marine seismic vessels.

In an effort to provide the best marine platform from which to gather seismic data, in 1995 PGS launched a revolutionary hull design, called Ramform. This new design satisfies three key attributes necessary to advance seismic data gathering.

1) Minimal engine noise entering the water.

2) A wide back deck providing an extremely flexible and safe platform for deploying equipment, personnel, and machinery (including helicopters).

3) Excellent stability at the stern, providing minimal pitch and roll. PGS launched the 3rd generation of this design, Ramform Sovereign this year. It is easily the most powerful seismic ship in the world and features many innovations, including the world's first roll compensated helideck, steerable sources, dual workboat capacity and unique gear handling systems.

Previously, in the shipboard geophysical control room, data was viewed on a wall of individual monitors. The challenge was to create a display environment where data could be viewed in a coherent manner and reconfigured as requirements changed. The solution for providing proficiency and flexibility of data acquisition and monitoring was made possible, in part, by GCCD's ergonomic design of the new shipboard Geophysical Control Rooms, featuring two curved display walls displaying an array of data. Each display wall is comprised of three edge-blended projectors fed by an RGB Spectrum MediaWall® 2500 display processor. The processor accepts RGB and DVI format inputs from a multitude of computers generating high-resolution graphics, maps and seismic images. The processor formats these into easily positioned and scalable windows.

Rolf Erik Leistad of Global Control Center Design states, "The MediaWall 2500 made it possible to create an ergonomic high resolution working environment for the management of the visual information." Leistad believes the capability of the installation is enhanced by the MediaWall's ability to flexibly combine the multiple high-resolution images as well as to provide the overlapped outputs needed for edge blending. When asked about the overall performance of the MediaWall 2500, Leistad responded, "Impressive! In the end, it's all about a satisfied user, happily working in a coherent ergonomic environment."
