Paris, France – June 12, 2024

Viridien, formerly CGG, has been selected by Groupement Berkine; a joint venture between Sonatrach, Occidental Petroleum, and other international partners, to perform the seismic imaging of a 3,400 sq km high-density onshore data set currently being acquired over blocks B404a and B208 of the Berkine Basin in Eastern Algeria.

To deliver new subsurface insight and, in particular, sharpen the resolution of the target area’s thin and faulted geology, an expert team of scientists at Viridien’s advanced Subsurface Imaging center in France will apply an advanced imaging workflow to the dataset, drawing on their experience of imaging similar large and ultra-dense land seismic surveys in the Middle East.

Peter Whiting, EVP, Geoscience, Viridien, said: “Viridien has been selected to conduct this high-profile project in recognition of its ongoing development of best-in-class imaging technology and significant high-performance computing capabilities. This, together with our long track record in Algeria, dating back to the 1950s, in-depth geological knowledge of the Hassi Messaoud Basin, and recent successful completion of a series of reimaging projects in the country, makes Viridien the preferred partner for delivering the best-possible subsurface images for critical field development decisions.”
