Petroleum Geo-Services Awarded Largest-Ever HD4D Campaign

Petroleum Geo-Services ASA has been awarded by Petroleo Brasileiro S.A. a contract to undertake the largest High Density 4D (HD4D) marine seismic survey campaign ever in the industry, based on a tendered contract value of US$251 million.

President & CEO Jon Erik Reinhardsen in PGS states in a comment, "This contract is an important strategic milestone to PGS, as we are providing the most sophisticated technology in the business, with the newest vessel in the industry, in the area where the world's most significant recent discovery is made."

The award is comprised of a "Firm Program" of five surveys, totaling 4,945 square kilometers and an "Alternative Program" of up to an additional 120 days of data acquisition. The Campos, Santos and Espirito Santo Basin surveys are scheduled to begin in October 2008, using PGS' latest state-of-the-art vessel, the Ramform Sovereign, which was christened in Alesund, Norway on March 12, 2008. The current estimated contract value to PGS is US$180-200 million.

High Density Time Lapsed surveys are used for reservoir management as they require optimal seismic quality in terms of resolution and repeatability. PGS' Ramform technology is tailored for these requirements due to the size and density of its streamer spreads. The Ramform Sovereign will provide Petrobras with the largest, most efficient spreads available to the industry -- 18 streamers x 6,000m streamer length x 50m streamer separation or 14 streamers x 8,000m x 50m, depending on Petrobras' subsurface imaging requirements for each survey area.

According to Mike Edwards, PGS' Marine VP South America, "PGS continues to show its long term commitment to Brazil by offering its most recent ultra-high capacity vessel for this exciting, long term Petrobras campaign. The Ramform Sovereign will reduce the data acquisition time required by standard configurations. This will decrease Petrobras' commercial exposure and enable them to begin interpreting the final product much, much sooner than previously expected."

"PGS has shown tremendous commitment to Brazil. By offering the latest Ramform technology PGS and Petrobras will be able to take yet another step in our ongoing technological cooperation. The Ramform Sovereign is a superb choice from business and technical perspectives as she is the most advanced seismic vessel available in the industry today," quoted Mario Carminatti, head of Petrobras' Exploration Department.
