TGS Launches Major Seismic Reprocessing Campaigns in Newfoundland and the Norwegian Sea

Using modern depth‑imaging with machine learning, the work improves imaging quality so explorers can better evaluate risks to prospects.

Overview

TGS announced on Wednesday that it has started the Orphan3D PSDM Phase 2 reprocessing offshore Newfoundland and publicly launched the Atlantic Margin South reprocessing in the Norwegian Sea.
The Atlantic Margin South program covers more than 23,000 km² and will deliver interim early‑out products in Q3 2026 and a seamless full‑integrity volume in Q2 2027.
Orphan3D Phase 2 will upgrade roughly 13,300 km² of 3D data with early products due in 2027 and final migrated volumes scheduled for delivery in Q3 2027.
Both projects will apply advanced workflows — including Full Waveform Inversion variants, Dynamic Matching elastic FWI, machine‑learning denoising, adaptive demultiple and proprietary depth imaging — to sharpen subsurface images.
The industry‑funded, multi‑client programs target specific geologic challenges — Orphan3D for Cretaceous and Jurassic intervals and Atlantic Margin South for volcanic imaging to derisk gas prospectivity — and could influence licensing, exploration planning and investment decisions.
