Shell is preparing to start a 3D seismic survey over Block SK 319 off Sarawak, East Malaysia.

The supermajor has contracted Polarcus for the five-week shoot, which it will perform with the 12-streamer seismic vessel Polarcus Alima.

The survey will be supported by three Malaysia-flagged vessels: Nur Barakah, Nur Cekal and Seacrest Warrior.
