Sercel Extends Capability of 508XT Seismic Acquisition System

CGG announced that Sercel has launched a transition zone version of its state-of-the-art 508XT seismic acquisition system. Seismic crews will now be able to deploy the 508XT solution in marsh zones and water depths of up to 25 m.Designed with reinforced hardware to withstand the complex challenges of operating in shallow water environments, the new 508XT transition zone system also benefits from Sercel’s unique fault-tolerant X-Tech cross-technology architecture, featuring local storage and automatic rerouting to maximize survey productivity. With its 100 percent real-time monitoring capability

Sercel Sells High-res Streamer System to AWI Research Institute

CGG announced that Sercel has sold one of its new Sentinel HR high-resolution solid streamers to the Alfred Wegener Institute (AWI), a German research foundation specializing in polar and marine research in the Arctic and Antarctic.   AWI will use the Sentinel HR on research projects it is conducting to record critical data about the relationship between geological activity and ecosystems in order to gain a better understanding of the Earth’s system.    Launched in 2017, Sentinel HR is the latest member of Sercel’s Sentinel solid streamer family. With a close channel

CGG Completes Perdido Subsalt Survey for Pemex

set is expected to provide significantly enhanced subsalt imaging results. A fast-track TTI RTM image for the first block of approximately 5,200 sq. km was delivered earlier than planned, helping to guide the client’s drilling operations. This landmark survey also saw the first deployment of Sercel’s QuietSea next-generation Passive Acoustic Monitoring (PAM) system in the Mexican Gulf of Mexico after receiving accreditation from ASEA, Mexico’s oil and gas environmental authority. The system was seamlessly integrated into the five-vessel WAZ fleet and demonstrated its reliability

Further Milestones for QuietSea PAM System

 Sercel said its QuietSea Passive Acoustic Monitoring (PAM) system, which is seamlessly integrated into seismic streamers to detect the presence of marine mammals during seismic operations, has passed two milestones.   Most recently, the U.S. Bureau of Safety and Environmental Enforcement (BSEE) authorized the use of QuietSea for seismic survey operations in the U.S. waters of the Gulf of Mexico. The U.S. authorities recognized that the ability to use geophysical survey streamers for PAM was a great step in the future development of effective PAM systems.   Another milestone was

Sercel Sells 10,000 UNITE Nodes to NIS

CGG announced that Sercel has sold 10,000 channels of its high-end UNITE cable-free land seismic acquisition system to NIS, the Serbian oil and gas company in which Gazprom Neft has a majority shareholding.   After having successfully deployed the UNITE system since 2014 in Romania, NIS have now decided to purchase a new complete batch of UNITE for survey projects that they will be conducting over the next several years. In combination with the Sercel SG-5, a high-sensitivity 5-Hz single-sensor geophone, UNITE offers NIS a superior, light, efficient and flexible solution for the most complex

CGG Launches Shallow Reservoir Imaging Solution

places CGG’s broadband source over a customized receiver spread, combined with proprietary imaging.   Turning the concept of shooting-over-the-spread acquisition into reality required a team of experts from multiple CGG business lines, including marine, multi-client, subsurface imaging and Sercel equipment.   TopSeis will play a key part in a forthcoming integrated geoscience study, including an extensive commercial survey CGG plans to acquire in the Barents Sea in 2017. This will offer other early adopters of this new technology the opportunity to benefit from the anticipated step-change

reservoirs, which are mostly now part of the Onerous Transfer of Rights Agreement, between Petrobras and the Union (Brazilian Government). BroadSeis Technology CGG’s BroadSeis technology is based on a marine broadband seismic data acquisition system, combining the use of sensitive low-noise Sercel Sentinel streamers configured to optimally curved, variable-depth, streaming profiles, with an average depth of over 40 m, and 3D de-ghosting. The combined use of the optimized Sentinel streamers and very deep and stable towing has delivered an excellent signal-to-noise ratio at the lowest frequencies

Offshore Oil & Gas: Brazil’s Northern Frontier

Margins of Brazil have been a core area for our investment campaigns over recent years.” The project has received high prefunding from a number of major industry players and covers an area of 11,330 sq. km. The Foz do Amazonas Basin survey is being acquired by the MV Oceanic Endeavour deploying Sercel’s next-generation Sentinel RD solid streamer and started in January 2014. The Sentinel RD has a reduced diameter and a 15% weight reduction, compared to the original Sentinel, providing reduced cable drag and increased storage capacity aboard the seismic vessel.
