TGS, a global leader in energy data and intelligence, announces the completion of the PGS24M02NWS and PGS24M04NWS 3D seismic surveys in the Vøring Basin on the mid-Norwegian continental margin. The newly acquired data strengthens subsurface understanding of this geologically complex volcanic province and supports more robust evaluation of exploration potential through modern acquisition and advanced processing.
The surveys build on existing GeoStreamer coverage in the Vøring area. Acquisition was carried out using wide-tow triple sources to improve near-offset illumination, deep-tow multi-sensor GeoStreamer technology to enhance signal-to-noise ratio, and extended streamers optimized for full waveform inversion. Broadband processing workflows, including machine learning-based noise attenuation, were applied to support improved imaging of deeper intrusive bodies and complex stratigraphy.
David Hajovsky, Executive Vice President of Multi-Client at TGS, said, 'These completed 3D surveys deliver a consistent, high-quality seismic volume that supports improved interpretation of structure and stratigraphy in the Vøring. In settings affected by extensive volcanism, modern acquisition and processing are critical to reducing uncertainty and supporting informed exploration decisions in the region.'
The Vøring Basin has seen limited exploration drilling over the past two decades. Discoveries to date, including Obelix, Irpa,Balderbrå and Haydn/Monn have primarily encountered gas in Paleocene and Upper Cretaceous reservoirs, while the Aasta Hansteen field remains the only developed discovery in the area. Attempts to prove Lower Cretaceous and Jurassic targets have so far been unsuccessful, underscoring the technical challenges associated with imaging beneath volcanic and intrusive sequences.
A major Paleocene to Early Eocene magmatic episode introduced widespread intrusions and hydrothermal vent complexes that have influenced reservoir architecture, maturation and fluid migration across the basin. Continued advances in seismic acquisition and imaging along the Atlantic Margin over the past decade have significantly improved the ability to resolve these features and assess their role within the petroleum system.
The completed PGS24M02NWS and PGS24M04NWS surveys form part of TGS’ effort to deliver modern, high-quality regional-scale seismic coverage that enables operators to reassess mature and frontier areas of the Norwegian margin with greater confidence.
