TGS Brand Guidelines: Tomlinson, NOPEC, PGS & a Seismic Data Library

A Houston seismic firm and a Norwegian consultancy.

TGS has two starting points, one in each of its home cities. English Wikipedia names Prentis Tomlinson as the founder, in 1981, of Tomlinson Geophysical Services — the TGS of the name — and says the company in its present form came from a 1998 merger of that business with Calibre Geophysical, also founded in 1981, and NOPEC International, a Norwegian company whose name stood for Norwegian Petroleum Exploration Consultants. Norwegian Wikipedia dates the listed company to 1998.

The merged group took the name TGS-NOPEC Geophysical Company, listed its shares on the Oslo Stock Exchange and split its head office between the two traditions: a financial headquarters in Oslo and an operational headquarters in Houston, according to English Wikipedia. Norwegian Wikipedia says the company used that long name until 2021, when it became simply TGS.

Its business model set it apart from contractors that shoot seismic surveys for a single client. Norwegian Wikipedia describes TGS as a collector of marine seismic data that shoots surveys on speculation and sells the results to many clients — the multi-client model — with a library concentrated in the Gulf of Mexico and the North Sea, gathered for most of its history with chartered vessels rather than its own fleet. It also built up a collection of digital well logs, the records of measurements taken down boreholes.

The company says it now offers well and log data, reservoir characterisation, imaging and data management alongside seismic data, and describes a library covering mature, emerging and frontier basins worldwide, from deepwater and pre-salt plays to the Arctic and onshore North America.

Nodes on the seabed, then a fleet of its own.

In the early 2020s TGS moved from buying and licensing data toward collecting it. Its first big step was Magseis Fairfield, a specialist in ocean bottom node acquisition, in which sensors are placed on the seabed rather than towed behind a ship. TGS says it acquired the company on 5 January 2023, after the completion and settlement of its offer, and ran it at first as a separate business unit within the group.

The second step was PGS. Petroleum Geo-Services was founded in Norway in 1991 and listed on the Oslo Stock Exchange in August 1992, according to Norwegian Wikipedia. It focused on marine geophysics after selling its onshore business in 2010, operated a fleet of seismic ships, and was headquartered at Lysaker outside Oslo until 2013, when it moved to nearby Lilleaker, English Wikipedia says.

On 18 September 2023 TGS and PGS announced the principal terms of a combination. World Oil reported that day that TGS shareholders would own about two-thirds of the combined company and PGS shareholders about one-third, and that the group would cover multi-client data, towed-streamer acquisition, ocean bottom node acquisition, imaging and new energy data, with an operational fleet of seven 3D acquisition vessels and around 30,000 seabed nodes. Both the British and Norwegian competition authorities approved the deal, Norwegian Wikipedia says.

The merger was completed on 1 July 2024 and registered with the Norwegian Register of Business Enterprises, Offshore Engineer reported the next day, after approval from the UK Competition and Markets Authority cleared the last hurdle. The combined company kept the TGS name, and PGS ceased to exist as a separate listed company.

Design and documentation.

Oilfield service companies sell work that most people never see. Their customers are oil and gas producers, and the jobs happen thousands of metres underground, on remote well pads or on the seabed. So the way these firms present themselves leans on a small set of recurring pictures: crews in branded coveralls and hard hats on a rig floor, frac fleets of pump trucks lined up on a well pad, and service trucks parked at a wellsite with the company name on the door.

Offshore, the pictures change but the method is the same. Remotely operated vehicles hang from launch frames, supply and support vessels sit in a harbour or alongside a platform, and seismic ships tow their streamers across open water. Onshore and offshore alike, the firms photograph their engineering and manufacturing centres too: test bays, laboratories and workshops where pumps, tools and chemicals are made or checked before they go to the field.

Much of the communication is technical. Companies publish papers through industry bodies, case studies that set out a customer’s problem and the tool used to solve it, product data sheets and long catalogues of named technologies. Product names tend to be coined words or trademarks attached to a function — a drilling system, a lift pump, a monitoring service — and many firms keep the names of companies they bought alive as product brands.

Two further registers sit alongside the technical one. Safety pages describe procedures, training and reporting in the industry’s own vocabulary, and investor presentations explain backlogs, contracts and market cycles to shareholders. For many of these firms, mergers, spin-offs and restructurings are part of the history, so the name on the coveralls may be newer than the tools the crew is using.

A redesigned logo with elements from PGS.

The merger came with a new look. On the day of completion TGS unveiled a new brand identity, Offshore Engineer reported in July 2024. The company described the redesigned TGS logo as a blend of heritage, innovation and financial strength, and said it kept elements from the PGS brand to signal the combined company’s continued work in technology and operations. The chief executive, Kristian Johansen, said the refreshed identity was meant to show the group as a strategic partner for energy companies.

TGS today describes itself as an energy data and intelligence company with headquarters in both Oslo and Houston, nearly 2,000 employees and key offices in the UK, Egypt, Brazil, Kuala Lumpur and Perth. Its shares trade on the Oslo Stock Exchange, where it is part of the OBX index, and over the counter in the United States, the company says.

Its acquisition fleet comes from PGS. The company says it operates seven Ramform vessels fitted with steerable multisensor GeoStreamer technology, alongside ocean bottom node acquisition and its Gemini source, and that it processes and images data in-house. The multi-client library remains the centre of the business: TGS says it typically targets projects that earn sales of two to two and a half times their investment, and asks for high levels of pre-funding on projects with lower expected returns.

The company also presents data for markets beyond oil and gas — offshore wind, geothermal energy, offshore minerals and carbon capture and storage — which the merger announcement of 2023 already counted among its growth areas, according to World Oil.

For a design guide, TGS shows how a merged company can carry the visual memory of a partner into a new logo. Compare SLB, another oilfield services company, and Subsea7, an offshore group also listed in Oslo. For this guide we use survey navy, a streamer blue and seabed sand with a sans, an unofficial interpretation; no product or logo is reproduced.
