The 9024 km2 survey will provide 3D broadband PSDM imaging for the first time in an area that has recently re-opened for exploration following the ratification of the Maritime Boundary Treaty.
TGS anticipates significant uplift in quality beyond the original PSTM data which was acquired in 2012. Utilisation of modern imaging techniques, including FWI, will enable a significantly enhanced evaluation of the prospectivity of the area. The application of Broadband PSDM will facilitate better penetration and the removal of ghost signals for more accurate wavelet construction, improved coherent noise suppression and more precise velocity modelling.
Will Ashby, Executive Vice President, Eastern Hemisphere at TGS, commented: “Applying the extensive imaging expertise of TGS to the Kyranis 3D survey will be a key enabler for exploration on both sides of the border. We are confident that the application of our Broadband PSDM sequence will successfully overcome the challenges created by the complex seafloor in this region to create a sharper, more accurate image.”
The reprocessing of the Kyranis 3D survey has been supported by industry. Fast-track deliverables are expected in 4Q21 with final deliverables due 2Q22.
