Viridien (VIRI), formerly CGG, is a multinational technology, digital and Earth data company, specializing in solving complex natural resource, energy transition and infrastructure challenges.

In his premises at 30 rue Fabert, in Paris, Conrad Schlumberger decided to transfer the subsurface business to CGG while SPE retained the logging.

In 2015, CGG applied new full-waveform inversion and reverse-time migration imaging technologies on massive regional-scale, multi-client datasets in Norway, Gabon and the Gulf of Mexico.

Viridien focuses on environmental insight (on land, ocean, or atmosphere) through remote sensing, machine learning analytics, data analysis and interpretation, and high performance computing (HPC).

[11] Some of the environmental projects in which Viridien has worked on include conducting microplastics pollution surveys as part of a study for an effort to create a Plastic Free zone at Yr Wydffa (Snowdon).

[12] Viridien utilizes monitoring technology and digital twin models to understand an infrastructure’s life span, condition and maintenance needs.

[13] One of the known applications of Viridien infrastructure monitoring technology is in its work on the "Connected Bridges" project for a French public body.

In December 2023, it was announced by environmental group Seaspiracy that CGG had been granted authorization by the South African government to conduct seismic blasting between Plettenberg Bay and Gqeberha.

This backlash mirrored a similar response to attempts by Shell PLC and Shearwater Geo to conduct seismic blasting off the Wild Coast in December 2021.
