OSLO, Norway — A consortium of TGS, PGS and SLB has signed a reprocessing agreement to expand multiclient 3D coverage over the Sarawak province offshore Malaysia.

This will involve reprocessing legacy datasets to complement and merge with newly acquired phases.

Last August Petronas awarded a contract to acquire and process up to 105,000 sq km of multiclient 3D data in the basin over a five-year period. The second phase of the acquisition program is underway over blocks ND-3 and SK-3B and will be merged with about 6,700 sq km of reprocessed data.

"The Sarawak basins comprise a proven petroleum system with many producing fields already present in the Central Luconia province,” said Nathan Oliver, PGS' executive vice president of sales and services. “Through the addition of… reprocessing of legacy data on a multiclient basis, PGS and partners will be able to high grade areas and merge with newly acquired GeoStreamer data to improve regional understanding of the petroleum systems and leads mapping in frontier blocks. This will ultimately lead to accelerated projects and renewed phases of acquisition.”

In May of this year, PGS, TGS and SLB arranged pre-funding for a new 6,885-sq-km multiclient 3D seismic survey offshore the North Luconia Province in the Sarawak Basin offshore Malaysia. The Ramform Sovereign was due to start acquiring the survey in June using GeoStreamer technology and is scheduled to finish the campaign in August.
