TGS has launched a big data reprocessing project in the East Java Sea that will improve exploration insights across the South Makassar and North East Java regions.
The East Java Sea 2D-cubed project will utilize 2D-cubed technology to integrate all existing seismic data across a 270,000 km2 area to create a one-stop tool for regional evaluation.
The dataset will combine more than 120,000 km of 2D seismic data from more than 80 legacy surveys into a single exploration tool and create a well data package comprising 88 wells. The final multi-client product, supported by Ditjen Migas, Pusdatin ESDM, SKK Migas and Pertamina, will comprise a single conformable seismic volume will allow customers to develop structural and geological models in their pre-study evaluation process, said TGS.
This project covers significant acreage in the 2nd 2021 Indonesian Licensing round, including the Agung-I and Agung- II blocks. Early project deliverables are expected from Q2 2022.
2D-cubed is a proprietary technology from TGS that generates a 3D seismic volume from a set of 2D lines. It uses an advanced structurally conformable interpolation algorithm to maximize the potential of existing 2D multi-vintage and 3D data. The resultant volume can be used for both regional interpretation and the optimization of subsequent 3D and 2D survey designs. TGS has undertaken similar large-scale projects in other Asia Pacific basins in places such as Timor-Leste and Australia. This technology has also been applied offshore Sakhalin, Russia, and throughout the Norwegian and UK North Seas.
Kristian Johansen, CEO at TGS, said: ‘This regional product will enable exploration companies to efficiently assess hydrocarbon prospectivity and initiate studies on vast volumes of data in unprecedented timeframes.’
