Viridien Advances Côte d’Ivoire Reimaging Scheme in Tano Basin
Viridien has launched the CDI25 project, a 6,555 km2 seismic reimaging endeavor in the Tano Basin in Côte d’Ivoire, delivering a drill-ready multi-client dataset for explorers pursuing opportunities along the West African Atlantic margin.CDI25 is part of a larger Côte d’Ivoire subsurface reimaging program that Viridien began four years ago, designed to systematically upgrade seismic data and interpretation confidence across the basin.The program is applying Viridien’s processing and imaging workflows, including Ghost Wavefield Elimination (GWE), advanced de-multiple
Sierra Leone Grants Offshore Survey Permit to Shell
Sierra Leone has signed an agreement with Shell that allows the oil major to conduct advanced geological and geophysical surveys across multiple offshore blocks, the country's petroleum directorate said on Wednesday.The reconnaissance permit agreement covers an area of approximately 20,600 square kilometres and includes basin modelling and petroleum systems analysis, a statement said.The programme, similar to one signed with Eni ENI.MI last October, is expected to enhance understanding of Sierra Leone's deepwater hydrocarbon potential.The permit will provide a data-driven framework for technical
TGS to Advance Offshore Seismic Development In Equatorial Guinea
Energy data and intelligence firm TGS has signed a strategic agreement with the Republic of Equatorial Guinea to acquire, process and promote seismic and geophysical data across the country’s offshore basins.The agreement covers the reprocessing of legacy seismic datasets as well as the acquisition of new data, aimed at improving subsurface understanding and supporting exploration activity in the region.Under the deal, TGS will apply its imaging technologies to reimage existing datasets of varying vintages and deliver an integrated approach combining seismic acquisition, processing and interpretat
DeepOcean, Woodside Wrap Up Dual-Scope Subsea Survey at Sangomar Field
DeepOcean and Woodside Energy have completed a combined subsea inspection and 3D scanning campaign at the Sangomar field offshore Senegal.The campaign covered 69 subsea structures, including 17 subsea trees, using a methodology that allows inspection and 3D scanning to be performed simultaneously.DeepOcean said the approach enabled the work to be completed in slightly more than half the time required for two separate operations, while increasing the amount of data collected.The work used remotely operated vehicles equipped with scanning systems and software to generate digital 3D models of subsea
TGS Targets Eastern Niger Delta with New 3D Survey
Energy data and intelligence provider TGS has launched the Nigeria Laide multi-client 3D seismic survey offshore Nigeria in partnership with the Nigerian Upstream Petroleum Regulatory Commission (NUPRC) and SeaSeis Geophysical Limited.The survey covers approximately 11,700 square kilometres within the Outer Fold & Thrust Belt of the eastern Niger Delta, one of Nigeria’s most prolific hydrocarbon regions.The Laide 3D survey is designed using the GeoStreamer dual-sensor system with long offsets, wide tow and a triple-source configuration.The acquisition is intended to deliver modern broadband
TGS Embarks on Multi-Client 2D Survey off Angola
seismic data critical for imaging complex pre-salt and top-salt structures as well as basin floor channel systems, significantly enhancing regional geological understanding.“Angola’s ultra deepwater margin represents one of the most exciting frontier exploration opportunities in West Africa. Our Ultra Profundo multi-client 2D program delivers high-quality seismic coverage needed to unlock pre-salt and sub-salt potential. By leveraging TGS’ acquisition and imaging capabilities, we will provide high-quality data supporting future exploration activities,” said Kristian Johansen
TGS Moves to Expand Multi-Client Seismic Data Activity in Libya
Energy data and intelligence firm TGS has signed a Letter of Intent (LOI) with North Africa Geophysical Company (NAGECO), a subsidiary of the Libya National Oil Corporation (NOC), marking an important step toward expanding multi-client data activities in Libya.The LOI establishes a framework that enables further multi-client collaboration with TGS, subject to final contractual arrangements and regulatory approvals.The collaboration reflects a shared commitment to advancing high-quality subsurface data and supporting Libya’s upstream development through modern, fit-for-purpose data and technology
Viridien, SLB Set to Launch ‘Massive’ OBN Survey Offshore Egypt
Viridien and SLB have entered into an agreement with the Egyptian Natural Gas Holding Company (EGAS) to launch a massive multi-client ocean bottom node (OBN) seismic acquisition and imaging program in Egypt’s Eastern Mediterranean offshore.The largest project of its kind in the region, it will combine the recognized OBN expertise of both parties to deliver an unparalleled subsurface dataset for Egypt and international exploration partners.This project will give explorers and investors a clearer understanding of the region’s complex subsurface and help them identify new opportunities for
Viridien Completes Reimaging of BM-S-2 Multi-Client Survey in Santos Basin
Viridien has successfully completed the BM-S-2 seismic reimaging project in the southern Santos Basin, delivering a modern, high-fidelity 3D dataset across 8,468 sq km to support growing exploration activity in one of the most strategic, emerging offshore regions of Brazil.The project upgrades a large legacy survey with the latest advanced imaging technologies, including time-lag full waveform inversion (TL-FWI), to provide clearer definition of post-salt stratigraphy, improved visibility of potential direct hydrocarbon indicators (DHIs), and new insights into underexplored pre-salt plays. The reimaged
