OSLO, Norway – TGS has started processing for the East Java Sea 2Dcubed project, designed to help promote exploration in the South Makassar and Northeast Java regions.
The company will apply 2D-cubed technology to integrate all existing seismic data over a 270,000-sq km (104,248-sq mi) area. Its dataset will combine more than 120,000 km (46,332 sq mi) of 2D data from over 80 legacy surveys, creating a package that will include data from 88 wells.
Ditjen Migas, Pusdatin ESDM, SKK Migas, and Pertamina are supporting the program which will result in a single conformable seismic volume, allowing users to develop structural and geological models for their pre-study evaluations.
Included is acreage offered in the 2nd 2021 Indonesian License round, such as the Agung-I and Agung-II blocks. TGS expects to release first results from 2Q 2022.
The company developed 2D-cubed to generate a 3D seismic volume from a set of 2D lines. It employs a structurally conformable interpolation algorithm to maximize the potential of existing 2D multi-vintage and 3D data, TGS said, with the results suitable for regional interpretation and optimization of subsequent 3D and 2D survey designs.
Previously the company performed similar projects in basins off Timor-Leste and Australia, as well as offshore Sakhalin, eastern Russia, and the North Sea.
