Key Terms

nace mr0175 technical

NACE MR0175 is an industry standard that specifies which metals and manufacturing practices are safe for use in oil and gas environments that contain hydrogen sulfide, a corrosive gas that can make some metals crack. For investors, compliance is like a safety and quality badge: it reduces the risk of costly equipment failures, regulatory fines or project delays, and affects supplier choice, warranty exposure and capital costs in energy and industrial projects.

coiled tubing technical

Coiled tubing is a long, flexible length of pipe wound on a large reel that can be unspooled and pushed into oil and gas wells to clean, repair, measure, or perform light drilling without removing the main wellhead. Think of it like a continuous garden hose or fishing line that lets technicians reach deep down quickly and repeatedly. Investors care because coiled tubing services affect production uptime, repair costs and service-company revenue; efficient use can lower operating expenses and speed returns on well investments.

plug and abandonment technical

Plug and abandonment is the permanent closure of an oil or gas well: workers place barriers down the well, remove surface equipment, and restore the site so the well cannot leak or be used again. For investors it matters because it is a legally required, often costly cleanup process that converts future production into a one‑time expense and ongoing liability risk—similar to tearing down and safely sealing an old factory, with implications for cash flow and balance‑sheet reserves.

blowout preventer technical

A blowout preventer is a large, heavy-duty valve assembly installed on oil or gas wells that can quickly seal the well if pressure control is lost, stopping an uncontrolled release of hydrocarbons. Think of it like an emergency brake or shutoff valve for a pipeline: its proper function reduces the risk of catastrophic spills, regulatory fines, costly shutdowns and litigation, so investors watch its condition and testing as a measure of operational safety and financial risk.

slick line technical

Slick line is a single, smooth metal cable used to lower and retrieve simple tools, plugs or gauges inside an oil or gas well; think of it like a fishing line that drops down the well to move or check parts without dismantling equipment. It matters to investors because slick-line work is a relatively low-cost, quick way to fix production issues, perform routine maintenance and reduce downtime, which directly affects a well’s output, operating costs and near-term cash flow.

subsea test tree technical

A subsea test tree is an assembly of valves and instruments installed on an underwater oil or gas well to control, monitor and sample fluids during testing or short-term operations; think of it as a remote control panel and set of gauges attached to the wellhead on the seabed. It matters to investors because reliable testing confirms how much oil or gas can be produced, influences production start dates, safety and environmental risk, and can drive project costs and future revenue estimates.

landing string technical

A landing string is the short set of characters or tracking details appended to a web link that directs a reader to a specific page tied to a press release or announcement. Think of it as a digital address plus a name tag: it both sends people to the right page and lets the issuer see where visitors came from. Investors use landing-string data to gauge how much attention an announcement is getting and how effective outreach or investor-relations campaigns are.

Advanced equipment technology delivers one valve shear and seal on wire and coiled tubing

HOUSTON--(BUSINESS WIRE)-- Energy services provider Expro (NYSE: XPRO) today unveils Solus™ – the unique high-debris single shear and seal ball valve system offering additional flexibility, functionality, and safety to subsea well access solutions for the international oil and gas industry.

Expro's Solus™ Technology

Replacing the conventional requirement for two valves with just one, Solus™ revolutionizes the industry’s approach to subsea well access, reducing operational risk and complexity while accelerating the drive toward more cost-efficient subsea intervention technologies.

Tested and validated in accordance with API Std 17G, Solus™ is the first fully NACE MR0175 compliant fail-close bi-directional high-debris ball valve system that can shear and seal on wire and coiled tubing.

Expro’s Solus™ advanced equipment technology can be used in both in riser and open water applications across the entire well lifecycle - from exploration and appraisal and completion intervention to plug and abandonment (P&A) and decommissioning.

Solus™ has already been deployed for a new in-riser completions development in the Gulf of America and installed in an open water system for a North Sea P&A campaign. The system provides shear and post-shear seal for gas and liquids on slick line, braided electrical cable, and coiled tubing. It delivers bi-directional sealing for liquids and gas, even after a pump-through.

Solus™ has also been included in the Expro lightweight P&A Open Water Intervention Riser System (OWIRS). By achieving a Shear and Seal in a single valve, this technology allows Expro to introduce Solus into the open water application.

Solus™’ modular design allows isolation and disconnection from the well. Its compact design and increased flexibility match the industry’s advance in next generation smaller-sized BOP (blowout preventer) stacks and enables more efficient supply chain management.

The system’s fail-close design reduces risk of emissions and provides a unique well safety barrier. Expro’s world-class integration or ‘whole system’ experience provides user surety and confidence. Replacing a two-valve system with just one valve simplifies operations management.

Solus™ offers superior high debris (HD) flexibility for a wider range of complete well lifecycle challenges, with 15% solids ingress qualification size.

Solus™ is the latest technology from Expro that demonstrates the company’s innovation and expertise in systems integration, engineering excellence, and deep understanding of the industry’s needs. The system advances Expro’s 40-year legacy of leadership in the global subsea sector.

Daniel More, Vice President Subsea Well Access, said:

“In introducing Solus™, Expro now offers the subsea engineering market a distinctive new system that provides the ultimate integrated shear and seal on coiled tubing and wire using just a single valve. Solus™ cuts through operational complexity. Simple to use, flexible, with a compact design for smaller BOP stack sizes, this is the latest in fail-safe technology developed by the experts of valve technology and systems integration.

“When there’s no room for error, Solus™ is designed to provide the assurance of an independent well safety barrier, combined with the surety and confidence that comes from Expro’s integration experience and expertise at the ‘whole system’ level. It’s the latest example of Expro’s engineering excellence and deep understanding of customer needs to move our industry forward.”

Solus™ is available in Expro’s ELSA landing string assemblies equipment offering. It is available in-riser as a single valve, a single valve with a latch mechanism, or within a subsea test tree, and within an OWIRS.

For more information on the Solus™ technology, Expro will be hosting a live webinar on March 4^th 2026. Details can be found here: Expro’s Solus™ Webinar
