Expro_1990s_subsea1 40 years since the launch of its first subsea test tree system, Expro, a leading energy services provider, has remained at the forefront of subsea landing string technology.

The first 10ksi subsea test tree assembly (SSTTA) was created for an exploration and appraisal well project for Hamilton Brothers in the North Sea in 1983. Several of its SSTTA technologies have been on a first to market basis and have helped to progress the sector’s capabilities over the years. Expro has now undertaken more than 3,000 subsea deployments in exploration and appraisal, completion, and intervention applications, and remains a global leader in large-bore SSTTA solutions.

Other subsea well access major milestones Expro has achieved over the years have included the introduction of the first 7 3/8” 10ksi horizontal tree completion landing string system; the launch of the industry’s first 6 ¾” high debris SSTTA system; the release of the first large bore 6 ¾” 10 ksi subsea electro hydraulic control system; unveiling the first 6 ¾” 10ksi dual bore and mono-bore subsea test tree offshore; revealing the first 15ksi 6 1/8” horizontal tree SSTTA and electro-hydraulic control system; and the development of 7 3/8” 10ksi high debris SSTTA.

The evolution of subsea test tree assemblies has allowed the company to expand into the open water well intervention market through the introduction of both riser-based and riser-less well intervention solutions. Such success and dedication to subsea well access application even earned the company the accolade of Intervention Champion of the Year at the recently-held OWI Global Awards 2023.

At the company is showing no signs of building on its successful history. In a bid to continue this history, it has sought to boost its subsea capabilities by acquiring PRT Offshore, the only company to offer a complete Hook-to-Hanger solution enabling comprehensive well completions, interventions, and decommissioning services from surface to subsea. The acquisition enables Expro to expand its portfolio of cost-effective, technology-enabled services in the North and Latin America region and accelerate the growth of PRT Offshore’s surface equipment offering into the Europe and sub-Saharan Africa and Asia Pacific regions.

“At Expro, we’ve been first to the market with many of our subsea test tree assembly products and, as future technical challenges arise, we believe that with our customer-bespoke solution philosophy, we’ll continue to be at the top of the subsea test tree application,” remarked Graham Cheyne, Expro’s Vice President of Subsea Well Access.

“From starting in 1983 supporting operators in the Norwegian North Sea, we’ve become a global player in all parts of the world, supplying fully integrated technologies and services from surface to seabed – the hook to hangar concept. The subsea test tree market operates in the full well lifecycle – from exploration and appraisal through to abandonment and decommissioning while continually looking to improve our delivery and operational performance, and service quality to our global client base.

"Whilst leading in this market for over 40 years with many first to market technologies we are committed to delivering the new technology requirements of tomorrow in order to meet our customer needs whilst maintaining the high level of service quality and customer care.”
