PGS ASA was a Norway-based geophysical services company that provided seismic data and subsurface imaging solutions to the global energy industry. Its services supported oil and gas exploration, field development, reservoir management and carbon storage projects.
The company operated a fleet of advanced seismic vessels and developed proprietary technologies for acquiring, processing and imaging marine seismic data. PGS also built and licensed multi-client geophysical data libraries, allowing energy companies to access regional subsurface information without commissioning a dedicated survey. Its offerings included seismic acquisition, data processing, imaging, interpretation and related consulting services.
PGS served customers across major offshore energy regions, including areas in the North Sea, the Gulf of Mexico, Brazil, West Africa and other international markets. The company was headquartered in Oslo and was led for much of its later independent history by Rune Olav Pedersen, who served as president and chief executive officer.
In 2024, PGS completed a merger with TGS ASA, creating a combined geophysical data and technology company. PGS’s former seismic acquisition and imaging operations became part of the combined TGS organization.
