Global energy intelligence and data provider TGS has begun work on the 7,856 square mile Peninsular Malaysia Phase 2 Regional 3D Reprocessing Project.
TGS said this second phase of the Peninsular Malaysia reprocessing project was part of a multi-year basin revitalization initiative being carried out in partnership with DownUnder GeoSolutions.
Combined with the 7,856-square-mile Phase 1 project, the data coverage represents one of the largest multi-client 3D reprocessing projects ever undertaken in Asia, the company said in its statement.
Thirty-two 3D seismic surveys will be reprocessed in Stage 2, comprising a combination of vintages covering retained acreage, MBR license blocks and open acreage in the Malay Basin, TGS noted.
TGS said the result will create a single contiguous Pre-Stack Time and Pre-Stack Depth Migrated (PSTM and PSDM) 3D volume using a workflow that uses FWI, Q-Migration and Q-Tomography to maximize image clarity , especially with complex functions. like gas clouds.
According to the company, it will give oil and gas companies access to a modern regional-scale dataset that will enable the assessment of the Malaya Basin.
In line with Malaysia’s 2050 carbon neutral target, continued expansion of this data set will enable improved regional mapping and structural understanding and identification of new opportunities for exploration and carbon capture and storage , TGS said.
“Through the latest stage of our extensive 3D reprocessing project, we continue to support exploration in the Malay Basin to enhance future exploration and help meet gas supply challenges,” said Kristian Johansen, CEO of TGS.
The project is financed by the sector. Final deep and time migrated products are expected in mid-2025, although interim products will be available much earlier, the statement said.
