TGS develops 3D dataset offshore East India


Overseas staff

ASKER, Norway — TGS has published the results of the first phase of its reprocessing project on the east coast of India.

This applies to hundreds of thousands of kilometers of existing 2D data over an area of ​​over 0.5 million kilometers off eastern India.

TGS is deploying its 2D cube technology to generate a 3D seismic migration volume from 2D seismic lines, with the goal of developing a single, compliant and easily accessible dataset to support exploration offshore India.

Will Ashby, TGS executive vice president for the Eastern Hemisphere, said the new dataset will help explorers develop regional models in their pre-survey assessment process.

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

Final data cubed in 2D and ready for the workstation should be delivered by the end of July.

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

The acquisition for the second phase of the 3D project in the Egyptian sector of the Red Sea, in a joint venture with Schlumberger, will be completed in the coming days. Final data from the first phase should be available early next year.

A consortium of TGS, CGG and BGP continues to acquire data for the Suriname 3D survey. The acquisition is expected to complete at the end of Q3 2022, with final data deliveries expected in 2023.

TGS and PGS began acquiring the Cameron Canyon 3D survey offshore eastern Canada in early June. The data acquisition part will end in October, with the processed data to be ready next year.

Acquisition of the NOAKA22 Ocean Knots Survey in the Norwegian North Sea, which builds on last year’s NOAKA21 survey, is expected to be completed in early Q4 2022, with final processing deliverables ahead of be published in the fourth quarter of 2023.

In June, the company’s New Energy Solutions business launched what TGS claims is the world’s first multi-client 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 further improve/validate the company’s high-resolution coverage of Numerical Weather Prediction model data. The results will be accessible in near real time on the TGS Wind AXIOM platform.
