Offshore Sabah Multi-Sensor 3D/2D

Designed to qualify reservoir distribution, unlock deeper play fairways, and reduce exploration risk.

The first MultiClient survey in Malaysia shows potential to be the world’s largest, and will bring together the latest in multi-sensor technology, reservoir imaging, and towed streamer electromagnetic technology, to unlock the potential offshore Sabah.

After years of canvassing by the Oil & Gas community, a data access model initiative is underway.  A dataset designed to stand the test of time, that will provide regional insight through to prospect identification, whilst unearthing variability in reservoir quality will be commercially available to the industry.

The consortium of PGS, TGS, and WesternGeco provide industry prowess in global experience, financial capability, and technology excellence to ensure the success on behalf of the Malaysian Petroleum Management division of PETRONAS, the owners of this industry changing pilot project for Malaysia.
