TDI-Brooks successfully completed and safely performed multiple shallow hazard surveys off the East Coast of Trinidad for Perenco T&T Limited. TD-Brooks’ research vessel RV PROTEUS operated geophysical survey equipment such as 2DHR seismic, side scan sonar, magnetometer, sub bottom profiler and multi-beam echosounder.

The primary objective for these projects is to identify potential hazards and factors of operational significance relative to the placement of drilling rigs. This involves exploring and defining shallow gas accumulations up to depths of approximately 2,000 feet below mud line (BML) or 2.0 seconds two-way time (TWT) through the acquisition and interpretation of high-resolution 2D seismic data. The focus also extends to the identification of seafloor obstructions, investigation of the proposed area's seabed for potential man-made and geological hazards, and the determination of water depth and seafloor conditions.
