CGG Wins Multi-year Processing Contract

Subsurface Imaging, part of CGG’s Geoscience division, has been awarded a processing contract by the Abu Dhabi National Oil Company (ADNOC), CGG announced on Tuesday.The French based geosciences company said it will perform high-end time and depth imaging of massive volumes of very high-spec data from what is believed to be the world’s largest ocean-bottom node (OBN) seismic survey to date.Starting in May 2019 – and for a period of at least five years, during the maximum seven-year contract period – CGG will process a minimum 20,000 square kilometers of high-density wide-azimuth

provided this improvement in imaging at the subsalt Mad Dog Field. Project cycle time was significantly reduced, when compared to projects where the velocity model was constructed using discrete interpretation methods. FWI provided a fast-track velocity model that facilitated a superior migration for depth imaging just weeks after delivery of the OBN data.Sophie Zurquiyah, CEO, CGG, said, “CGG has demonstrated again that it is the provider of choice in OBN imaging around the world, particularly for subsalt imaging in the deepwater Gulf of Mexico. With our advanced technology and close collaboration

The latest Q modeling, and Q-compensating imaging techniques bring greater clarity to Northern Viking GrabenCGG has recently completed seismic depth imaging of its entire Northern Viking Graben multi-client survey, in the Norwegian North Sea. The latest visco-acoustic (“Q”) velocity modeling and seismic imaging technologies have been applied to BroadSeis broadband variable-depth streamer field data, acquired between 2014 and 2016. The final output forms a contiguous data volume covering 35,400 km².The Northern Viking Graben, like many other areas around the globe, contains a wide

CGG Wins 6-year Contract for Brunei Shell Petroleum

will run for a period of six years, from January 1, 2017 to December 31, 2022.   Under the terms of the contract, CGG will deliver the full scope of processing services for 2D, 3D and 4D seismic data acquired onshore and offshore Brunei, ranging from field data processing to advanced pre-stack depth imaging, using advanced processing and subsurface imaging technology.   In addition, CGG will add value to Local Business Development by committing to recruit and develop local geoscience-related personnel and execute business opportunities locally.

shot.  The crew of the CGG Geo Caspian worked in partnership with the client to complete the program ahead of schedule.  According to CGG’s CEO, Jean-Georges Malcor, “This exceptional achievement surpasses our record last year when we delivered 1,700 sq km of fast-track depth imaging data just nine days after acquisition for another survey offshore Morocco for the same client. It reflects the dedication of our offshore and onshore experts to go the extra mile to deliver results that continue to exceed our clients’ expectations.&rdquo

O&G JIPs Target Seismic Imaging, Cyclone Forecasting

over the last nine years to $11.5 million. Fullwave Gamechanger Phase II aims to deliver an advance in seismic imaging leading to enhanced prospect evaluation and reservoir exploitation. The new phase builds on the work carried out on the technique of full-wavefield inversion, a method for seismic depth imaging which helps to more accurately map the presence of hydrocarbons. Project Director, Professor Mike Warner of Imperial College London said, “The launch of the Phase II work is vindication of the significant strides that our team has made in the application of advanced seismic analysis

PGS to Reveal Triton Success at AAPG

The new PGS MultiClient Full Azimuth (FAZ) GeoStreamer survey represents the next advance in tailored acquisition design and state-of-the-art depth imaging. Petroleum Geo-Services (PGS) will share more information about the success of its Triton Full Azimuth (FAZ) GeoStreamer survey at this year’s AAPG in Houston. PGS said Triton is the first ever MultiClient survey to use the unique PGS Orion configuration, part of a survey design which has been developed to reveal the structures obscured beneath the salt in this area like never before. Using this configuration, combined with PGS’
