In 1926, Conrad Schlumberger, and his brother Marcel Schlumberger, formed Société de Prospection Electrique (SPE) which specialized in oil and coal exploration as well as civil engineering.

In March 1931, SPE and Société Géophysique de Recherches Minières (SGRM), both specialists in seismology and magnetometry, merged into La Compagnie Générale de Géophysique (CGG). SGRM provided 5,000,000 francs of capital and CGG provided 120,000 francs of capital. In his premises at 30 rue Fabert, in Paris, Conrad Schlumberger decided to transfer the subsurface business to CGG while SPE retained the logging. At the same time, Raymond Maillet from SGRM was appointed President of CGG.

In 1954, CGG acquired its first IBM 604 computer and an MT4 analog computing center for processing field data.

In 1958, CGG completed its first dual-vessel marine survey with one source vessel.{{Cite web |last=Haq |first=Ali |date=2011-09-12 |title=80 Years of Discovery |url=https://geoexpro.com/80-years-of-discovery/ |access-date=2025-04-16 |website=GeoExpro |language=en-US}}

In 1966, CGG opened its first seismic data processing center in Massy, France.

In 1971, CGG started 3D marine seismic exploration with wide-line profiling .

Veritas Energy Services, a geophysical services company, was established in 1974 in Calgary, Alberta, Canada with the purchase of a Rafael Cruz owned firm Rafael B. Cruz and Associates Ltd. by David B. Robson.

Meanwhile, Digital Consultants Inc. had been established in Houston, Texas in 1965. In 1969, Digital Consultants reincorporated as Digicon Inc. (DGC), becoming a public company on the American Stock Exchange.

In 1977, the a single-channel cable telemetry system used for extreme conditions, SN348, was introduced.{{Cite web |title=History of Sercel {{!}} Sercel |url=https://www.sercel.com/en/about-sercel/sercel-profile/history-of-sercel |access-date=2025-04-16 |website=www.sercel.com}}

In 1979, commercial depth migration was offered.

In 1994, 4D seismic surveys were carried out.

In 1996, Veritas DGC was formed from the merger of Veritas and Digicon.

Then in 2000, the company began imaging 4D time-lapse seismic data for carbon storage injection and monitoring.

The company became CGGVeritas through its merger with the North American company Veritas in 2007.

CGGVeritas acquired Norwegian company Wavefield Inseis in December 2008.{{cite web | title=CGG: Our History 2009 | url=http://www.cgg.com/default.aspx?cid=6035 | publisher=CGG | accessdate=15 May 2015}}

In September 2012, CGGVeritas acquired Fugro's Geoscience Division for €1.2 billion,{{cite web |url=http://www.cggveritas.com/default.aspx?cid=5488 |title=Transforming CGGVeritas into a Leading Integrated Geoscience Company |website=CGGVeritas.com |date=24 September 2012 |access-date=2 April 2021 |archive-date=23 September 2015 |archive-url=https://web.archive.org/web/20150923202114/http://www.cggveritas.com/default.aspx?cid=5488 |url-status=dead }} and changed back its name to CGG.

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.

In 2019, CGG introduced time-lag full-waveform inversion.

In 2020, CGG exited seismic acquisition services.

In May 2024, CGG officially rebranded to Viridien.{{cite web | url=https://www.energyconnects.com/news/technology/2024/may/cgg-rebrands-as-viridien-a-step-towards-advanced-technology-and-earth-data-solutions/ | title=CGG Rebrands as Viridien: a step towards advanced technology and Earth data solutions | access-date=October 25, 2024 | website=EnergyConnects.com | date=25 October 2024 }}

Viridien develops geoscience technology to find natural resources and manage those resources sustainably. The organization focuses on oil and gas exploration, development and production; mineral exploration and mine development; and geothermal monitoring.

Minerals and mining: Viridien supports mineral exploration through global geological predictions and plate kinematic studies, satellite-derived surface material alteration targeting, provision of geophysical equipment, and the development and provision of modeling software, as well as monitoring services for mining operations and mine tailing storage facilities.{{cite web | title=Minerals & Mining Resources | url=https://www.cgg.com/industry-applications/energy-transition/minerals-mining-services | publisher= CGG}}{{cite web | title=CGG Launches MineScope | date=11 April 2019 | url=https://www.barsc.org.uk/cgg-launches-minescope-for-essential-insight-throughout-the-mining-lifecycle/ | publisher= BARSC }}

Geothermal: Viridien provides global screening datasets, as well as evaluating and monitoring geothermal developments to gain insight across asset life cycle by utilizing: data and analytics, resource assessments, reservoir characterization, and production and monitoring.{{cite web | title=CGG wraps up global geothermal study for energy major | date=20 October 2020 | url=https://www.upstreamonline.com/energy-transition/cgg-wraps-up-global-geothermal-study-for-energy-major/2-1-896473 | publisher= Upstream, NHST Media Group | accessdate=20 October 2020}}

This includes geoscience (subsurface imaging, geology, reservoir, technology function) and Earth data.

Earth data includes the vast Viridien library of Earth data and digital ecosystems for data that assists in natural resource development and energy transition applications.

Sercel designs and manufactures solutions for subsurface exploration, structural monitoring, defense and underwater acoustics.

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.

The announcement stirred backlash from environmental groups and South African civil society. 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.{{cite web | url=https://www.heraldlive.co.za/news/2023-12-10-nelson-mandela-bay-anti-seismic-survey-protesters-blast-cgg-authorisation/ |title=Nelson Mandela Bay anti-seismic survey protesters blast CGG authorisation | website=Herald Live | language=English| date=10 December 2023 }}{{cite web | url=https://www.sabcnews.com/sabcnews/activists-threaten-to-bring-shell-to-its-knees-amid-protests-against-plans-to-conduct-a-seismic-survey/ |title=Activists in SA threaten to bring Shell to its knees amid protests against plans to conduct a seismic survey | website=SABC| language=English| date=5 December 2021 }}
