ASKER, Norway  TGS has issued first-phase results from its East Coast India reprocessing project.

This applies to hundreds of thousands of kilometers of existing 2D data across an area of more than 0.5 million km offshore eastern India.

TGS is deploying its 2D-cubed technology to generate a 3D seismic migration volume from 2D seismic lines, the aim being to develop a single conformable, easily accessible dataset to support exploration offshore India.

Will Ashby, TGS' executive vice president of the eastern hemisphere, said the new dataset would help explorers develop regional models in their pre-study evaluation process.

“Access to this data will also increase confidence in license round decision-making processes and maximize the potential of existing seismic data in the region by employing innovative processing techniques,” Ashby said.

Final 2D-cubed, workstation-ready data should be delivered by the end of July.

In its latest results statement, TGS highlights some of its ongoing offshore seismic acquisition programs elsewhere.

Acquisition for the second phase 3D project in the Egyptian sector of the Red Sea, under a joint venture with Schlumberger, will finish in the next few days. Final first-phase data should be made available early next year.

A consortium of TGS, CGG and BGP continues to acquire data for the Suriname 3D survey. Acquisition should draw to a close in late third-quarter 2022, with final data deliveries expected in 2023.

TGS and PGS started acquisition of the Cameron Canyon 3D survey offshore East Canada in early June. The data acquisition part will complete in October, with the processed data due to be ready next year.

Acquisition of the NOAKA22 ocean-bottom node survey in the Norwegian North Sea, which builds on last year’s NOAKA21 survey, should complete in early fourth-quarter 2022, with final processing deliverables set to be issued in fourth-quarter 2023.

In June, the company’s New Energy Solutions business started what TGS claims is the world’s first multiclient offshore wind measurement campaign, in the New York Bight area off the US east coast.

The campaign, which will continue for two years, is designed to enhance/further validate the company’s high-resolution coverage of numerical weather prediction model data. Results will be accessible on a near-real-time basis in TGS’ Wind AXIOM platform.
