IRENA Geothermal Technology Report
JRG Energy, through contractor Witteveen & Bos, produced a geothermal technology report for IRENA. Work included a comprehensive literature review, a stakeholder consultation meeting coordinated with IRENA and IGA, and the preparation of a high-quality report covering the status, trends, and perspectives on geothermal technology globally.
High Enthalpy Geothermal Well Testing Workshop
JRG Energy delivered a high-enthalpy geothermal well testing workshop in the UK, drawing on its position as a trusted provider of geothermal well services and training. The workshop covered theoretical and practical aspects of well testing for high-temperature geothermal systems, equipping participants with skills applicable to international geothermal projects.
Geothermal Feasibility Study — Parisian Basin
JRG Energy supported Rockwater in preparing a feasibility study for integrating geothermal heat into a large-scale industrial application in the Parisian Basin. Work included destocking and reprocessing of legacy 2D seismic data, quick-look reservoir modelling, and geochemistry modelling. Outputs were used to assess project viability and support the conclusions of the feasibility study.
Reservoir Model Handover Training
JRG Energy delivered a reservoir training workshop in Paris to transfer knowledge of a dynamic semi-regional Dogger reservoir model developed for the Ile-de-France region. The model, built by JRG since 2023 and used across multiple predictive simulations, supports industrial geothermal resource management. The workshop equipped client engineers to independently run future simulations and covered model […]
Dunaújváros Maltings Plant Geothermal Feasibility
JRG Energy assessed geothermal heating potential for a malting plant in Dunaújváros, located approximately 70 km south of Budapest in the Pannonian Basin — one of Europe’s most prospective geothermal regions. The study evaluated the suitability of naturally porous and permeable sedimentary reservoir rocks for direct-use geothermal, assessing temperature, depth, and permeability requirements against the plant’s process heat demand to identify a viable low-carbon heating pathway.
Toulouse Matabiau Geothermal Technical Expert Review
JRG Energy was engaged by SAF-Environnement to conduct a technical expert review (Type M.2.2) of a geothermal district heating project in the Toulouse Matabiau area — a Segment 2 zone with less well-characterised geology. The review assessed the project dossier against current regulations and best practices to determine flow rate and temperature characteristics for the guarantee convention, identify compliance gaps, uncertainties, and risks, and […]
Paris, Aquitaine & Upper Rhine Graben Geothermal Modelling
JRG Energy has been providing ongoing geothermal reservoir modelling services to ENGIE across three major French sedimentary basins. Using Leapfrog for geological modelling and Waiwera for reservoir simulation, JRG has history-matched over 100 wells with production records dating back to the 1970s and simulated 234 MWth of new geothermal capacity — sufficient to supply heat to 150,000 people. JRG also delivers well […]
Cesano Geothermal Lithium Scoping Study
JRG Energy provided reservoir input to Altamin’s scoping study for a geothermal lithium project at Cesano. The scope included a review of legacy data, estimation of well output and resource longevity, and delivery of a concise technical report chapter suitable for inclusion in the scoping study. Conclusions were supported by calibrated wellbore models. Work was completed to Competent […]
Geothermal Lithium Red Flag Review, Poland
JRG Energy conducted a preliminary red flag review for Leo Lithium of a geothermal lithium project targeting the lower Permian reservoir in Poland, with reported lithium concentrations of 200–260 mg/L. The review assessed exploration work completed to date, direct lithium extraction (DLE) potential, geothermal output for district heating, CAPEX/OPEX estimates, district heating connection feasibility, and regulatory and permitting plans […]
Managed Pressure Drilling — Capacity Building & Equipment Procurement
JRG Energy supported Orllati Geothermie in developing their Managed Pressure Drilling (MPD) capability, successfully designing and procuring approximately $1M of equipment through a competitive tender. The scope also included well control capacity building, local permitting and regulatory support, and oversight of the first successful drill using the new equipment.MPD technology enables precise bottomhole pressure control […]
