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.
Aquaculture & Greenhouse Heating
JRG Energy completed a high-level assessment of geothermal potential within GEP-49 for a large aquaculture and greenhouse heating precinct. The review targeted the upper 250–500 m of the Wonnerup Member of the Lesueur Sandstone, mapping reservoir depth across the licence area to identify the most prospective zones for low-temperature direct-use geothermal development to support the proposed agricultural and food production operations.
Regina Deep Geothermal Heating
JRG Energy was selected by MacPherson Engineering to provide geothermal advisory services for the City of Regina’s deep geothermal heating facility, designed to supply energy to a new indoor aquatics centre. JRG’s role spans five project phases from pre-design through commissioning, fulfilling both the Global Advisor (facilitating site visits in Europe) and Local Advisor roles(through Aetna) specified […]
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 […]
