Advanced Drilling Know-How Becomes Critical as Geothermal Projects Push into Hotter, Deeper and Riskier Reservoirs

Bratislava, Slovakia – February 2026

As global decarbonisation targets accelerate and Europe expands its renewable baseload capacity, geothermal energy is moving from niche to necessity. Yet drilling continues to represent the single greatest technical and financial risk in geothermal projects, accounting for a significant share of total project costs. Operators are increasingly challenged by high-temperature and high-enthalpy reservoirs, corrosive brines, lost circulation, wellbore instability and the growing push toward superhot geothermal systems, all while navigating evolving safety and well control expectations.

Recent industry developments, including new geothermal well classification frameworks and the advancement of geothermal-specific well control guidelines, highlight a clear skills gap between conventional oil and gas drilling practices and the realities of geothermal well construction. Experts across the sector stress that success now depends on specialised engineering strategies covering HPHT metallurgy, directional drilling limitations at elevated temperatures, advanced drill bit technologies for hard rock, managed temperature drilling, and robust well integrity design.

Addressing these challenges, the Geothermal Drilling Technology & Engineering live online training will take place 9 – 12 March 2026, providing a technically rigorous and practice-driven programme focused on real-world geothermal drilling execution. The course explores geothermal well design fundamentals, rotary and directional drilling systems, downhole tools, tubular design and metallurgy, geothermal well control, drilling fluids, wireline and LWD, vibration management and the engineering considerations required for superhot wells. Led by a globally recognised geothermal drilling expert, the training equips engineers, operators and project stakeholders with the tools, methodologies and decision-making frameworks needed to reduce drilling risk, control costs and improve geothermal project performance in today’s rapidly evolving energy landscape.
