Shipwrecks Teem with Underwater Life, from Microbes to Sharks
Humans have sailed the world’s oceans for thousands of years, but they haven’t all reached port. Researchers estimate that there are some three million shipwrecks worldwide, resting in shallow rivers and bays, coastal waters and the deep ocean. Many sank during catastrophes – some during storms or after running aground, others in battle or collisions with other vessels.Shipwrecks like the RMS Titanic, RMS Lusitania and USS Monitor conjure tales of human courage and sacrifice, sunken treasure and unsolved mysteries.
TGS, Schlumberger reimaging central GOM
TGS-NOPEC Geophysical Company (TGS) and Schlumberger today announced a new multi- and wide-azimuth (M-WAZ) multiclient reimaging program in the highly prospective Central U.S. Gulf of Mexico. Final results are expected in early 2018, ahead of a period when substantial block turnover in the area is anticipated. The new Fusion M-WAZ reimaging program comprises data covering more than 1,000 Outer Continental Shelf (OCS) blocks (~23,000 km2) from 3D WAZ programs previously acquired by TGS and Schlumberger with the WesternGeco Q-Marine* point-receiver marine seismic system between 2008 and 2012. This large reimaging program will process data from the Mississippi Canyon…
Dual Coil Shooting Full-Azimuth Multiclient Acquisition in GoM
TGS and Schlumberger today announce commencement of the Dual Coil Shooting* multi-vessel full-azimuth acquisition Revolution XII and XIII surveys in the U.S. Gulf of Mexico. The surveys will cover approximately 7,150 km2 (306 blocks) in the Green Canyon, Atwater Valley and Ewing Bank protraction areas of the Central Gulf of Mexico. The Revolution XIl and XIII surveys will be acquired using the Schlumberger WesternGeco Q-Marine* point-receiver marine seismic system combined with the proprietary multivessel, Dual Coil Shooting acquisition technique, which will provide broadband, long-offset, full-azimuth data. This combination of leading-edge technology and technique will improve illumination and imaging of the sub-salt and other complex geologic features in this highly active region.
Gulf of Mexico Pipeline Contract for Technip
Technip wins Discovery System lump sum pipeline installation contract for Discovery’s South Timbalier Block 283 Junction Platform project. David Dickson, Technip’s Senior Vice President, North America Region, declared: “This award is the largest-diameter pipelay contract for Technip in the Gulf of Mexico, thanks to the acquisition of Global Industries. The pipelines will be installed between existing facilities in South Timbalier 280 and Ewing Bank 873 and the new platform in Block 283, at water depths ranging from 83 to 244 meters. • 13.9 kilometers of 30” pipeline. Technip's operating center in Houston, Texas will perform the overall project management and engineering. Offshore installation will be performed in 2013 with the G1200 as the primary installation vessel for all pipelay.
FairfieldNodal to Perform Survey for Marathon Oil
FairfieldNodal has signed a contract with Marathon Oil Corporation for an ocean-bottom node seismic acquisition survey. The survey is scheduled to begin in July and will run through the end of August. Marathon Oil will use the company’s Z3000 system at water depths of 200 to 600 meters in the Gulf of Mexico’s Ewing Bank area. The data acquired will help improve the quality and resolution of Marathon's existing dataset over the area. FairfieldNodal's cable-free ZNodal systems, available worldwide, are designed to acquire data in virtually any terrain or marine depth. Because they are completely self-contained, these small-footprint systems provide continuous data capture.
