Sabah Multisensor 3D GeoStreamer

Malaysia’s massive MultiClient 3D unlocks the hydrocarbon potential of the offshore Sabah province.
Website Map for Survey Sabah MC3D
Sabah MC3D has a footprint of 47 000 sq. km covering discoveries and multiple prospects. This JV project has grown steadily since Malaysia awarded its first MultiClient project in 2016 to partners PGS, TGS and WG.
There is a proven petroleum system within the fold and thrust belt in the Miocene turbidites, with many hydrocarbon discoveries. In 2018, a discovery well in the Sabah Trough became a new play opener for carbonate and syn-rift clastic plays.
The datasets have been acquired, almost exclusively, using multisensor technology to improve understanding of the regional petroleum systems and allow AVO analysis of prospects and leads.
