Geothermal Potential Screening Study — Continental USA

JRG Energy delivered a high-level geothermal potential screening study for the continental United States. Scope covered geothermal power generation potential across existing and new concessions, identification of established US industry partners, and a review of the regulatory and incentive framework including permitting, subsidies and tax incentives for geothermal development

Site Evaluation and Subsurface Hydrogeology for WavePark

JRG Energy assessed a proposed WavePark site for geothermal suitability, providing analysis of subsurface hydrogeology and geothermal characteristics. The report summarised site suitability for geothermal systems and evaluated the available options for integrating geothermal heating into the development at the current stage of project planning.

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.

Geothermal Consulting Support — Exploration Licences

JRG Energy provided on-demand consulting support to several geothermal explorers across Australia. Services included review of conventional and next-generation EGS potential, and description of geothermal exploration strategies suited to each tenement, covering geophysics and slim-hole drilling methods. 

Geophysical 3D MT/Gravity Modelling for Geothermal Exploration

Contracted by IGNIS Energy, JRG developed a combined Magnetotelluric and gravity 3D inversion model to identify and interpret subsurface geothermal features in Alaska. The integrated approach improved subsurface imaging, complementary data integration, and reservoir characterisation accuracy, delivering a comprehensive understanding of the geothermal potential and supporting informed decision-making for subsequent exploration and development.

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 […]

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 […]
