TGS has launched the ‘Declaration Refocus’ M-WAZ reimaging programme in Mississippi Canyon in the US Gulf of Mexico.
The programme comprises data covering more than 380 Outer Continental Shelf (OCS) blocks (~8860 km2) from orthogonal 3D WAZ programmes previously acquired by TGS using WesternGeco Q-Marine and CGG StagSeis seismic systems between 2010 and 2015. Full product delivery of Declaration Refocus is expected at the end of 2020.
The new imaging project will process data from the prolific Mississippi Canyon, Viosca Knoll and De Soto Canyon areas. Particular attention will be given to increasing frequency content and resolution throughout the entire data section with additional focus on the Norphlet formations, said TGS.
The imaging process will also provide enhanced velocity and salt models. The Declaration area will be subject to two licensing rounds every year under the BOEM 2017-2022 five-year programme.
Meanwhile, TGS has started its 2020 South Halfway 3D onshore seismic survey in the Inga/Fireweed area of North East British Columbia in Canada.
The South Halfway survey is the second multi-client onshore project this winter season in the NEBC Montney basin for TGS, complementing the recently announced Midnight 3D survey.
When completed, the South Halfway project will have added nearly 100 km2 of high-quality 3D seismic data and ties into existing TGS’ 3D seismic coverage in the area — exceeding 3,000 km2 over the highly prospective Montney acreage. A full suite of AVO-compliant reservoir characterization products, in addition to a suite of pre-stack depth-migrated deliverables, will be available in early 2020.
Kristian Johansen, CEO of TGS, said:‘The South Halfway 3D project further expands our comprehensive onshore library in the region.’
