TGS to Reprocesses Seismic Data for Petronas’ Megah Discovery
TGS has launched a 3D seismic reprocessing project covering about 514 square kilometers over Petronas’ Megah discovery in Block SB-3K offshore Sabah, Malaysia, with final products expected in April 2027.The project will apply TGS' Elastic Multi-Parameter Full Waveform Inversion and depth imaging technologies to its legacy Geostreamer Sabah multi-client 3D Phase 2 dataset, which was acquired in 2017.Processing began in July 2026 and will use a high-resolution velocity model and diffraction imaging across the Megah field. Petronas made the Megah discovery in 2025.The reprocessed data is

set will be imaged using Viridien’s elastic full-waveform inversion (E-FWI) to improve subsalt structural clarity and support further exploration in central Keathley Canyon. Early-out products will be available at the end of October in time for the offshore lease sale scheduled in December. Final products will be delivered in early the first quarter of 2027. “Together with TGS, we are acquiring high-quality OBN data and applying our most advanced imaging to give operators the clearest view of these promising yet complex subsalt plays. This collaboration continues to raise the bar for

.The initial phase of the Pelotas Basin 3D will be 3,800 sq.km, extending to 7,000 sq.km with a planned extension.The joint-venture partners have prior to this successfully acquired over 12,500 sq.km in the highly prolific Orange Basin with significant industry support from multiple clients.The final products of the four adjacent projects in the Orange Basin will be delivered upon completion of processing throughout 2024."It’s an exciting time as we build a fit for purpose organization to support Shearwater’s organic entry into multi-client. Together with complementary partnerships
CGG Releases Gulf of Mexico Carbon Storage Study
French seismic data specialist CGG has announced the delivery of the eastern phase of its GeoVerse Carbon Storage Gulf of Mexico Study and the start of the westward extension of the study. Both phases of the project, supported by industry funding, are available for license now with final products for the westward expansion phase available in Q1, 2024, CGG said.According to CGG, these studies provide an accurate, unique, and independent map-based assessment of carbon storage opportunities coupled with a desktop-ready well database and web-based visualization dashboards for informed and
