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.

The Malaysian Petroleum Management (MPM) under PETRONAS tendered for a basin scale MultiClient 3D survey offshore Sabah in early 2016. This was a step change for Malaysia to introduce the MultiClient model. The tender was awarded to JV partners PGS, TGS and WG in late 2016.

There is a proven petroleum system within the fold and thrust belt in the Miocene turbidites with many hydrocarbon discoveries to date. Carbonate and syn-rift clastic plays are being tested in the deeper waters.

  • 12 045 sq. km of new GeoStreamer multi-sensor technology has been acquired using a Triple Source configuration
  • Existing 5 933 sq. km of Sabah 3D and 10 018 sq. km of Brunei 3D provides a total of 28 000 sq. km of data in offshore Sabah to date
  • A further 23 000 sq. km 3D and 5 600 lkm 2D  broadband seismic is planned for acquisition

Access to acreage is available with >50% of the total area to be made available as open and relinquished blocks in the future.
