Viridien has initiated a new multi-client seismic reimaging project over offshore Angola's Block 22. The objective is to support the country's upcoming licensing round and provide operators with enhanced subsurface data in this prospective but underexplored region.

Project Scope and Timeline

The program covers approximately 4,300 square kilometers in the Kwanza Basin, focusing on structures along the Atlantic Hinge zone. This geological trend is analogous to the one containing the producing Cameia and Golfinho fields. Fast-track data products are anticipated in the first quarter of 2026, with final imaging deliverables scheduled for the third and fourth quarters of 2026.

Technology and Objectives

Viridien will deploy its latest proprietary seismic imaging technologies, including time-lag full waveform inversion (FWI), Q-FWI, Q-Kirchhoff migration, and advanced deghosting and demultiple workflows. The reprocessed dataset is specifically designed to improve the imaging of both pre-salt and post-salt geological plays in the area.

Regional Data Integration

This new program over Block 22 will complement Viridien's existing 2,900-square-kilometer multi-client dataset over nearby Block 20/11. Together, they will expand the total regional broadband Pre-Stack Depth Migration (PSDM) coverage offshore Angola to more than 7,200 square kilometers. The combined datasets are intended to facilitate regional play evaluation and prospect screening for operators prior to bid decisions.

Strategic Context

The initiative is part of Angola's broader effort to revitalize upstream investment and sustain long-term oil and gas production by offering new offshore acreage. The modern, high-quality seismic data from this project is expected to help operators reduce subsurface uncertainty and improve exploration outcomes in the upcoming licensing round.
