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 […]
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 […]
Gingerah Geothermal Pre-feasibility Study
JRG Energy delivered a pre-feasibility study for the Gingerah Geothermal(GEP-47) project, integrating geological, structural, hydrogeological, and geothermal reservoir data into a 3D conceptual model. Temperature modelling was performed using the Waiwera geothermal simulator, and an initial resource assessment evaluated viability for power generation using EGS technology. The study also benchmarked the project against comparable global projects and identified potential investors and off-takers.
Gran Canaria Deep Geothermal Feasibility & Drilling Programme
JRG Energy is providing technical assistance and project management for the AGEOGC EV feasibility study on deep geothermal resources in southeast GranCanaria. The scope covers project coordination, regulatory and IDAE compliance, geoscience data integration, conceptual and numerical reservoir modelling, resource evaluation and exploration well targeting, drilling programme preparation and IDS tender documentation, plus supervision of up to three ~2,700 m […]
Roseau Valley Geothermal Project
JRG Energy mobilised wireline personnel and equipment on short notice to support Iceland Drilling’s geothermal drilling programme in Dominica. The scope covered equipment procurement, downhole PTS data acquisition, wireline logging and well test management, reservoir and geochemical data analysis, and professional reporting — enabling IDC to fully characterise the Roseau Valley geothermal resource in support of Dominica’s […]
Hawaii Geothermal Development Roadmap
Commissioned by DBEDT (via Waika consulting), JRG Energy prepared a step-by-step roadmap outlining all elements required to bring a geothermal power station to life on Hawaii Island. Written for a broad stakeholder audience in accessible language, the report provides an overview of geothermal science, the full commercial development pathway, and investment decision-making steps — equipping government, communities, and developers with […]
St Andrews Beach Hot Springs Development
JRG Energy is supporting the development of a low-temperature geothermal groundwater system to supply naturally heated water for a proposed hot springs resort at St Andrews Beach Golf Course on Victoria’s Mornington Peninsula. The project targets the Lower Tertiary Werribee aquifer at 540–650m depth, with well test results confirming flows of up to 16.8 L/s at 43.3°C. Scope […]
