TGS has announced an expansion of 2D-cubed seismic coverage offshore Indonesia

TGS, has announced an extensive regional seismic imaging project that builds upon existing Indonesian seismic coverage. The Kutei 2D-cubed survey in the Kutei basin will extend north from the East Java Sea 2D-cubed project area that concluded in late 2022.

Will Ashby, Executive Vice President for the Eastern Hemisphere, said: "With the Kutei 2D-cubed project, TGS continues to demonstrate its commitment to driving exploration in Indonesia. As we add to our extensive regional data library, we enable exploration companies to utilise the latest seismic imaging techniques to extract the maximum value from the existing data in the region."

The adjacent East Java Sea 2D-cubed project received widespread industry praise. It was designed to help drive interest and exploration across the South Makassar and Northeast Java regions. The Kutei project will continue to build upon this coverage, utilising 2D-cubed technology to integrate all existing seismic data into a single, conformable exploration package. It will add a further 115 400 square km2 of 2D-cubed data, resulting in a single, expansive, homogenous dataset encompassing more than 380 000 square km2 offshore Indonesia.

The innovative 2D-cubed technology from TGS generates a 3D seismic volume from a set of 2D lines. It uses a structurally conformable interpolation algorithm to maximise the potential of existing 2D multi-vintage and 3D data. For the first time in Indonesia, this technology enables large databases of 2D to be matched and merged into a single tool to fast-track exploration. Where available, any legacy 3D seismic data will be post-stack merged into the 2D-cubed volume to allow for continuous regional coverage.
