CGG announced today its award by PETRONAS of a contract to acquire and process a 10,000km2 3D seismic survey program offshore Sabah and Sarawak in Malaysia using BroadSeisTM, CGG’s broadband marine solution.
The survey started in August and is due to last five months. The survey dataset will be processed in CGG’s Kuala Lumpur data center.
Two CGG vessels are being deployed to ensure the program is completed before the onset of the monsoon season. The Viking Vision and Geowave Voyager are deploying their respective 12 x 100 x 8100 m and 8 x 100 x 8100 m spreads in a BroadSeis configuration using steerable Sercel Sentinel® solid streamers equipped with Nautilus® streamer control devices.
BroadSeis has been selected to address the challenging geology in this area, ranging from carbonate layers to complex channels and shallow gas anomalies. With its market-leading bandwidth and low frequency content, in particular, it is expected to improve penetration for the imaging of deep targets and pre-carbonate reservoirs and enhance seismic inversion results.
BroadSourceTM, CGG’s broadband marine source, will also be used on one of the blocks, to enhance resolution of shallow targets and improve fault definition.
Jean-Georges Malcor, CEO, CGG, said: “Broadband technology has been generating increasing interest among our Malaysian clients in recent years. CGG is recognized as having a very strong track record of broadband acquisition and our BroadSeis solution continues to demonstrate its versatility as seen on a recent successful survey in shallow waters in Vietnam. This experience will be valuable for this contract, which includes a shallow water area, and marks our sixth BroadSeis survey in Malaysia since 2010.”
