WesternGeco has completed a hybrid seismic acquisition survey for Roc Oil using their newly deployed multipurpose vessel (MPV)—a first in the industry, Schlumberger said on Aug. 25.
The 340 square kilometer, 3-D seismic survey was acquired offshore Sarawak, Malaysia, using a triple source array with simultaneous recording by ocean-bottom nodes and a towed-streamer spread, all from a single seismic vessel.
The WG Vespucci MPV acquired the high-quality ocean-bottom seismic (OBS) data required around existing platform obstructions supplemented by streamer seismic data. Simultaneously acquiring the OBS and streamer data without having to employ multiple acquisition vessels and crews resulted in cost reduction and greater efficiency while achieving the survey objectives.
“Providing a hybrid OBS and streamer acquisition option with our multipurpose vessel versus a traditional OBS or towed streamer survey gave the customer a versatile and cost-effective solution to better fit their specific challenges and budget,” Maurice Nessim, president at WesternGeco, said. “This industry-first acquisition underscores our commitment to offering our customers innovative approaches to offshore seismic acquisition challenges.”
The WG Vespucci is one of three newly configured MPVs in the WesternGeco fleet. The WG Tasman and WG Cook are equipped with Q-Seabed multicomponent seabed seismic systems.
