Malaysia 2019 Licensing Round

Enhance your prospectivity assessments in Blocks SB 2T and 2H offshore Sabah, Malaysia

Blocks SB 2T and 2H offshore Sabah cover a proven but structurally complex petroleum system with highly prospective carbonate reservoirs.

To support your prospectivity assessments for the current licensing round, we recently acquired 19,000 km² of 3D broadband seismic survey in a joint venture with TGS and PGS that includes portions of these blocks.

Survey acquisition and processing details

The 3D broadband seismic survey was acquired using multimeasurement streamer technology and processed with broadband techniques to improve frequency content and structural imaging. Gravity and magnetic data were used to guide earth model building and supplement the seismic data for regional interpretation, particularly of basement structures.

Accelerate hydrocarbon discovery with improved seismic data quality

The higher-frequency content of the data enables better imaging of the

  • Ubah and Rohu lower tertiary thrust sheets
  • Sabah Trough
  • northernmost extent of Dangerous Grounds
  • Cenezoic rift system.

Improved illumination of the subsurface enhances prospect evaluations, improves estimation of potential reservoir geometry, and reduces exploration risk.
