Expro Brand Guidelines: A 1973 Great Yarmouth Well Tester That Merged With Frank’s

A North Sea well-testing firm on the Norfolk coast.

Expro began in 1973 at Great Yarmouth, on the Norfolk coast of England. English Wikipedia says it was founded by J. Trewhella, J. Ross and H. Green as Exploration & Production Services (North Sea) Ltd, with the aim of carrying out well testing in the North Sea. The company still describes itself as a provider of well solutions across the life of a well, and it is now run from Houston rather than Norfolk.

Its ownership changed several times. In 1986, English Wikipedia says, about 84 per cent of the company was bought by Flextech, and in 1992 the management bought the business back. Expro was first listed on the London Stock Exchange in 1994, and in 2006 it bought PowerWell Services, another well-management business.

In 2008 Expro became the subject of a contest. In May that year Halliburton made a takeover offer; the following month a rival offer came from Umbrellastream, a consortium led by the private-equity firm Candover with Goldman Sachs and AlpInvest. English Wikipedia says the Expro board rejected an improved Halliburton offer, a position backed by the High Court after an appeal lodged by a group of shareholders, and the Umbrellastream acquisition was completed in July 2008. English Wikipedia also records that the company filed for Chapter 11 bankruptcy protection in the United States in 2017.

Test trees, tubulars and autonomous tools.

Much of Expro’s engineering grew out of its well-testing work offshore. In a January 2024 release marking forty years of the line, the company says it launched its first subsea test tree system in the North Sea in 1983, a 10,000 psi assembly built for an exploration and appraisal well run by Hamilton Brothers. Expro lists later milestones in the Norwegian North Sea in 1995 and 1999 and in the Gulf of Mexico in 2003, and says it has carried out more than 3,000 subsea deployments.

Today the company groups its work into product lines it calls Well Construction, Well Flow Management, Subsea Well Intervention and Integrity and Production Solutions, with Coretrax listed alongside them. Under Well Construction it still uses the name Frank’s Tubular Running Services, alongside cementing technologies, downhole tools and drilling services. It describes its markets as running from exploration and appraisal to well decommissioning, and its website lists geothermal, carbon capture and hydrogen work beside oil and gas.

Named tools fill its news pages. In November 2021 it launched Galea, which it called the world’s first fully autonomous well intervention system; its iTONG system for autonomous connection make-up followed in 2022. In October 2026 Expro said iTONG had won the Best Controls, Instrumentation, Automation Technology – Upstream category at the Gulf Energy Information Excellence Awards. Newer launches include Solus, which the company describes as a single-valve solution for subsea well access (February 2026), and Velonix, an automated pipeline pigging system (September 2026).

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.

From Great Yarmouth to the New York Stock Exchange.

The largest change to the company came in 2021. Expro announced a merger with Frank’s International in March 2021, and on 4 October 2021 OE Digital reported that the all-stock merger had been completed. The combined company took the Expro Group Holdings name; at the announcement, the two firms had said Expro shareholders would own about 65 per cent and Frank’s shareholders about 35 per cent. Frank’s former chairman and chief executive became board chairman, and Expro’s chief executive, Michael Jardon, stayed in post. OE Digital reported that the group would be headquartered operationally in Houston, keep an operating presence in Lafayette, Louisiana, Aberdeen and other locations, and keep its principal executive office in the Netherlands. The shares trade on the New York Stock Exchange as XPRO.

Acquisitions have followed. Expro says it completed the purchase of PRT Offshore in October 2023 and of Coretrax, an Aberdeen maker of drilling and wellbore clean-up tools, with an effective closing date of 1 May 2024. In May 2026 it agreed to buy Enhanced Drilling, a Norwegian specialist in managed pressure drilling and riserless mud recovery, and on 23 July 2026 the company said that purchase was complete. By its July 2026 releases the listed company was calling itself Expro Ltd. Expro says Enhanced Drilling’s work has been mainly in the North Sea, the Caspian and the Gulf of America, and that Coretrax was bought from an investment group led by Buckthorn Partners. Expro says it employs more than 7,000 people in more than 60 countries; its website names Michael Jardon as chief executive, Sergio Maiworm as chief financial officer and Alistair Geddes as chief operating officer.

Its recent contract news shows the spread of that work. In September 2026 Expro said it had won a multi-product-line contract for a Canadian operator’s life-extension campaign offshore Newfoundland, covering well construction, well flow management and subsea well access for a 14-well programme due to begin in the first quarter of 2027.

For a design guide, Expro shows how a short name drawn from Exploration & Production Services has carried a business through private-equity ownership, restructuring and a transatlantic merger. Compare Halliburton, which bid for Expro in 2008, and Weatherford, another well-services group. For this guide we use a deep navy, a steel grey-blue and a flare amber with a sans, an unofficial interpretation; no product or logo is reproduced.
