TGS to carry out seismic reprocessing project offshore East India
Published by Nicholas Woodroof,
The project encompasses over 250 000-line km of existing 2D data across an area of over half a million km2 offshore India's east coast. TGS will utilise its proprietary 2D-cubed technology to create a single, conformable, easily accessible dataset. This product is designed to encourage and assist exploration endeavors offshore India.
This new dataset, the latest TGS initiative to provide seismic to enhance exploration potential across Asia, offers coverage of the prospective Krishna-Godavari Basin and West Bengal Fan. The data uplift will allow local and international companies to develop structural and geological models in their pre-study evaluation process using a single conformable 3D volume. This will increase confidence in license round decision-making processes and support further exploration.
2D-cubed is a unique technology from TGS for generating a 3D seismic migration volume from a set of 2D and 3D seismic lines. An advanced structurally conformable interpolation algorithm revitalises existing 2D multi-vintage and 3D data. The resultant volume can be used for both regional interpretation and the optimisation 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 to industry acclaim. This technology has also been applied offshore Sakhalin, Russia, and throughout the Norwegian and UK North Seas.
Will Ashby, EVP of Eastern Hemisphere at TGS, commented: "India will experience a significant increase in energy demand over the coming decades. TGS is pleased to be able to support the local energy industry to meet growing requirements by employing innovative processing techniques to maximize the potential of existing seismic data in the region."
This project, approved by the Directorate General of Hydrocarbons (DGH), is supported by industry funding. First deliverables will be made available to pre-funding companies from 1Q22.
