General Well Services — Rotokawa
JRG Energy led operations for implementation testing and data acquisition, essential to the development of the Rotokawa geothermal field. Services encompassed well testing, wireline logging, and data management, providing critical subsurface information to support ongoing field development planning and operations.
Well Stimulation and Perforation
JRG Energy served as site manager and supervisor for all third-party contractors performing a multi-stage well stimulation and perforation programme on geothermal wells in New Zealand. The scope covered contractor coordination, operational supervision, HSE management, and technical oversight to ensure safe and effective execution.
Direct-Use Feasibility Study — Dairy Application
JRG Energy performed a desktop feasibility study for a dairy client, assessing the viability of utilising existing geothermal resources for direct-use heating. The study evaluated available geothermal resources, system design options, and economic performance to determine the potential for integrating geothermal heat into dairy processing operations.
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.
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.
Reservoir Modelling: Gippsland Basin
JRG Energy was contracted to undertake reservoir modelling for a geothermal energy supply project in the Gippsland Basin. A comprehensive Leapfrog geological model was built and used to construct the simulation mesh. The model was calibrated to Natural State conditions against 40 existing wells with temperature data. High thermal gradients of up to 150°C/km were […]
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.
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.
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 […]
Peninsula Hot Springs Vendor Due Diligence
JRG Energy were engaged to prepare a vendor due diligence sales assessment for Peninsula Hot Springs, a leading geothermal mineral springs and wellness destination offering over 70 bathing and wellness experiences. The assessment provided prospective purchasers with a comprehensive technical overview of the site’s geothermal water infrastructure, supporting the proposed divestment of the facility.
