Key Terms

well testing technical

Well testing is the process of running a drilled oil, gas or geothermal well for a set period to measure how much fluid or gas flows, the pressure behavior, and the fluid’s composition. Investors use these results to judge whether a well can produce enough to be profitable, estimate recoverable reserves, and spot technical or environmental issues—similar to turning on a new faucet to check flow strength and water quality before committing money.

surface well testing technical

Surface well testing is the process of measuring how much oil or gas flows from a drilled well at the surface and observing pressure and fluid characteristics to judge the well’s performance. For investors, it’s like taking a live reading of a machine to estimate how much product can be produced, how quickly revenue might start, and what ongoing costs or safety and regulatory issues could arise—information that directly affects cash flow forecasts and asset value.

well intervention technical

Well intervention is work done on an oil or gas well after it has started producing to restore, boost, or safely manage output — like servicing a machine to fix a leak, clear a blockage, or replace worn parts. For investors it matters because interventions affect how much oil or gas a well yields, how long it stays productive, and the timing and size of repair costs and downtime, all of which influence revenue and asset value.

lithium medical

A soft, silvery metal used as a key ingredient in batteries, certain medicines, and industrial processes; think of it like the gasoline that powers many electric vehicles and portable electronics. Investors watch lithium because its supply and demand affect the cost and profitability of battery makers and automakers, so changes in production, new mines, or shifts in technology can quickly influence related company earnings and stock prices.

geothermal technical

Geothermal is heat drawn from beneath the Earth’s surface and used to generate electricity or provide direct heating and cooling, achieved by tapping hot rock, steam, or water through wells and using it like a natural hot-water heater. For investors it matters because geothermal projects can provide steady, long-lived energy output with low fuel costs, but require large upfront drilling and permitting outlays and carry site-specific technical and regulatory risks.

Expro partners with VERCANA GmbH (part of Vulcan Energy Resources GmbH and responsible for well engineering and drilling) to support first well in Europe’s largest geothermal and lithium cluster.

HOUSTON--(BUSINESS WIRE)-- Expro (NYSE:XPRO) is set to deliver well testing services for the first Schleidberg well as part of Vulcan Energy’s Lionheart Project - one of Europe’s most significant geothermal and lithium extraction developments.

Expro partners with VERCANA GmbH to support first well in Europe’s largest geothermal and lithium cluster.

The Lionheart Project, recently designated as a strategic initiative under the European Union’s Critical Raw Materials Act (CRMA), represents one of the largest geothermal and lithium extraction programs of its kind in Europe. The support further strengthens Expro’s position as a key delivery partner in the region’s growing sustainable energy sector.

Under the scope of work, Expro intends to provide a comprehensive suite of services, including its advanced GeoFlow™ Surface Well Testing package. These services support VERCANA GmbH’s and Vulcan Energy’s efforts to characterize the reservoir, assess fluid properties and develop high-performance geothermal energy and lithium extraction from its planned development.

Lionheart builds on Expro’s expanding geothermal portfolio in the region, following the recent successful well test delivery for a private developer of geothermal systems in Germany.

Expro, who have been servicing geothermal projects for over 40 years, plans to deliver the work through their European, Mediterranean and Caspian teams, leveraging expertise from across the company’s Well Flow Management and Well Intervention offerings. This aligns with Expro’s continued commitment to supporting Europe’s energy transition with scalable, high-impact solutions for low-carbon energy systems.

Andrei Ion, Managing Director for Europe, Mediterranean and Caspian, of Expro, commented: “We are proud to support VERCANA GmbH’s and Vulcan Energy on this landmark geothermal development. The Lionheart Project is not only strategically important for the region, but also a clear example of how innovation and adaptation of traditional oilfield services such as well testing and well intervention can help unlock the full potential of geothermal resources and critical raw materials like lithium.

“This partnership reflects the strength of Expro’s geothermal capabilities and our ongoing commitment to delivering safe, efficient, and future-focused services across Europe. We look forward to helping our clients achieve their energy transition ambitions.”

Marco Köpsel, managing director of VERCANA GmbH stated: “Partnering with Expro on the first Schleidberg well marks an exciting step forward in our mission to harness sustainable energy and critical raw materials. The expertise and innovative solutions provided by Expro will be instrumental in unlocking the geothermal and lithium potential of this pioneering initiative.”
