Viridien (formerly CGG) will be conducting seismic imaging for a project in eastern Algeria by Groupement Berkine -- a joint venture between Sonatrach and Occidental Petroleum, among other global partners 

CGG is supporting majors such as bp in subsurface digital strategies since they signed a multi-year global data transformation and curation agreement in 2022.

This imaging campaign will cover an area of 3,400 sq km, capturing high-density onshore data set over blocks B404a and B208 of the Berkine Basin. It will involve a team of scientists from Viridien, who will work out of the company's advanced subsurface imaging centre in France.  

Delivering new subsurface insight

The team will draw on their experience of imaging similar large and ultra-dense land seismic surveys in the Middle East to apply an advanced imaging workflow to this project's dataset, and deliver new subsurface insight. They will also work towards polishing the resolution of the target area’s thin and faulted geology. 

Peter Whiting, executive vice president - 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.” 

Last year, CGG's sensing and monitoring wing Sercel deployed its systems for a 3D mega-crew project in harsh terrain and desert conditions in North Africa.
