Key TRANSGEO Outputs Were Presented in Vienna

Hybrid
Location: Vienna, Austria
Date: 15.04.2026 - 16.04.2026
By: TRANSGEO
The TRANSGEO final conference, technical excursions, and project meeting marked the successful completion of the project and showcased its key achievements in repurposing abandoned oil and gas wells for geothermal energy. Participants reviewed feasibility studies, pilot results, and strategic recommendations while gaining practical insights through site visits. The project demonstrated that reusing existing well infrastructure can support the energy transition by reducing costs, improving energy security, and promoting sustainable use of existing assets. The events also strengthened international cooperation and laid the foundation for future geothermal initiatives across Europe.

TRANSGEO outputs complement each other and support different user groups throughout the geothermal project development process.

Who can use it?

How does it support geothermal development?

Well Assessment Tool

Municipalities, regional development agencies, geothermal developers, oil and gas companies, investors, geological surveys, researchers, and policymakers.

The publicly available online tool evaluates whether abandoned oil and gas wells are suitable for geothermal reuse. It combines geological, technical, and economic criteria to identify promising wells, helping users make informed investment and planning decisions while reducing exploration risk and project costs. The database currently contains information on more than 9,000 wells across five Central European countries.

Feasibility Studies – Ampfing, Lausitz, Gross Schoenebeck, Mihovljan, Savica, Pomurje, Hungarian Great Plain, Weinviertel

Municipalities, local authorities, energy utilities, industrial companies, agricultural users, investors, and project developers.

The site-specific feasibility studies assess the technical, economic, and practical potential of selected wells for geothermal reuse. They demonstrate whether a particular project is viable, provide evidence for investment decisions, and support the planning and implementation of real geothermal projects. The studies carried out for eight pilot sites serve as practical examples that can be replicated elsewhere.

Transnational Strategy and Action Plan

National and regional governments, policymakers, public authorities, energy agencies, development organisations, industry associations, and other stakeholders involved in the energy transition.

The Strategy provides recommendations, priorities, and concrete actions needed to accelerate geothermal well reuse. It identifies policy, regulatory, financial, and organisational measures, as well as the key stakeholders responsible for implementing them. It helps create favourable conditions for investment, supports coordinated decision-making, and facilitates wider deployment of geothermal projects across Central Europe and beyond.

The TRANSGEO Action Plan establishes a coordinated roadmap for scaling up geothermal well reuse through targeted policy recommendations, stakeholder collaboration, and measures that facilitate investment, implementation, and market uptake across Europe.
