Offshore Sabah Multi-Sensor 3D

This vast and expanding multi-sensor 3D MultiClient survey provides the best opportunity to unlock the petroleum potential of the enticingly prospective offshore Sabah province

This is the first MultiClient survey in Malaysia and it is set to be one of the largest in the world. A total 36 972 sq. km of high-resolution broadband 3D data is now available:

  • New data 31 039 sq. km multi-sensor broadband data acquired so far
  • Additional 5 933 sq. km reprocessed and merged legacy data 

 

Prospective Fold and Thrust Belt

The Sabah multi-sensor 3D data is ideal for both optimized infill development and exploring new opportunities alongside established plays in this exciting hydrocarbon habitat. Sabah has a proven petroleum system, within the Miocene-Pliocene fold and thrust belt, that is the location of numerous hydrocarbon discoveries and multiple producing fields.

The high-quality broadband seismic data shows the full complexity of the structures and reveals the seismic facies distribution with a level of detail that has never been seen before.

Sabah Trough and Dangerous Grounds

Discover the new exploration provinces of the Sabah Trough and Dangerous Grounds.

The high-quality broadband seismic images reveal, with rich clarity, the pre-rift and syn-rift sediments in multiple prospective basins. Basin opening carbonate and clastic plays are strikingly presented in 3D, offering a rare opportunity to observe complete petroleum systems, from deep-seated source rocks and migration pathways to potential reservoirs and competent seals.
