HOUSTON – Schlumberger subsidiary WesternGeco has completed a hybrid seismic acquisition survey offshore Sarawak, Malaysia, using its newly deployed multipurpose vessel WG Vespucci.
The 340-sq km (131-sq mi)3D seismic survey was acquired for Roc Oil using a triple source array with simultaneous recording by ocean-bottom nodes and a towed-streamer spread, all from a single seismic vessel.
TheWG Vespucci acquired the 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.
Maurice Nessim, president, WesternGeco, Schlumberger, said: “Providing a hybrid OBS and streamer acquisition option with our multi-purpose 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.
“This industry-first acquisition underscores our commitment to offering our customers innovative approaches to offshore seismic acquisition challenges.”
