Geothermal Well Testing — FEED, Procurement & Field Execution
JRG Energy delivered a comprehensive well testing programme for Halliburton in Saudi Arabia, covering front-end engineering and design, welltest equipment procurement, wellbore simulations, programme development, capacity building workshops, geochemical sampling, and fullfield execution — providing an end-to-end service across all phases of the geothermal well testing workflow.
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 […]
Montserrat Geothermal Well Testing Programme
JRG Energy developed and executed geothermal well tests on two wells in Montserrat for the island’s government. The full scope included front-end engineering and design, well test equipment procurement, wellbore simulations, programme development, geochemical sampling, and field execution — delivering a rigorous, independently managed testing campaign to characterise Montserrat’s geothermal resource for future development planning.
Philippines Geothermal Greenfield Due Diligence
JRG Energy conducted a due diligence assessment of a geothermal greenfield opportunity for INPEX in the Philippines. The scope encompassed a comprehensive literature review, fieldwork including fluid sampling and chemical analysis, geochemical modelling of thermal manifestations, review of magnetotelluric and gravity geophysical surveys, and recommendations for further assessments to advance the project towards a development decision.
South Brawley Geothermal Lithium Due Diligence
JRG Energy conducted technical due diligence of the South Brawley / NewRiver geothermal lithium prospect in the Salton Sea geothermal fields — one of the world’s most productive geothermal regions, with over 740 MWe of installed capacity across four fields. The assessment evaluated the geothermal and lithium resource potential of this actively spreading pull-apart basin setting, supporting Leo […]
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 to address narrow drilling […]
Enhanced Geothermal Systems — EGS Review, South Australia
JRG Energy was engaged to produce an executive summary review of a techno-economic study covering South Australian geothermal exploration licences. The review assessed the potential for next-generation Enhanced Geothermal Systems (EGS) across the Flinders West and Paralana prospects, with full field development and economics evaluated for the Paralana Omega prospect. JRG provided findings and recommendations based on geothermal industry expertise and comparable […]
