Data acquisition will be conducted by the vessel BGP Prospector and Viridien will leverage its advanced seismic imaging technologies, such as time-lag full-waveform inversion (TLFWI), to deliver high-resolution subsurface images.

Acquisition fieldwork will take place over two seasons: February-April 2026 and November 2026-April 2027, with most acquisition relevant to the key prospects on AREA OFF-1 expected to be completed in the first season. Fast-track results from seismic data acquired in the first season are expected in Q4 2026, with full PSDM results from the first season expected in Q2 2027.
‘This project expands Viridien’s multi-client data footprint and demonstrates the company’s confidence in the long-term potential of the southern Atlantic Margin in Latin America as basins offshore Uruguay share strong parallels with Namibia’s Orange Basin, where recent major light oil discoveries have confirmed a working Aptian petroleum system,’ said Viridien in a statement.
Robert Bose, chief executive officer of Sintana Energy, said: ‘We are excited to see activity on AREA OFF-1 beginning so soon after completion of our acquisition of Challenger Energy in December 2025. 3D seismic acquisition is a key next step in defining the potential of Uruguay’s offshore embedded within our transatlantic portfolio, and which is underpinned by a relationship with Chevron that spans the conjugate margins. We look forward to providing further updates on progress over the coming quarters.’
Sintana Energy holds a 40% non-operated interest in the AREA OFF-1 block, after the farm-out in 2025 of a 60% operating interest to an affiliate of Chevron, and is carried for the total anticipated cost of the 3D seismic acquisition program.
Seismic acquisition follows rejection by courts in Uruguay of interventions by activist groups, which Sintanta said demonstrated ‘the robustness of Uruguay’s environmental consultation and permitting process.’
Meanwhile, Viridien and BGP have entered into an agreement with the government of Guyana to launch a multi-client 3D seismic acquisition and imaging program across the shallow water acreage lots 2, 3 and 4, an area comprising approximately 25,000 km2.
Data will be acquired by BGP and seismic imaging will be performed by Viridien, applying its proprietary advanced workflows, including shallow-water demultiple and time-lag full-waveform inversion (TLFWI).
