Capillary Tubing Installation — Cerro Prieto
JRG Energy designed and installed a capillary tubing system for geothermal production wells at Cerro Prieto in Mexico. The system was engineered to deliver inhibitor or other treatment fluids to downhole locations, addressing operational challenges and extending the productive life of the wells.
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.
Geothermal Well Enhancement
JRG Energy worked as part of a team that introduced and executed a reservoir enhancement technique targeting calcite and silica scale removal in the Philippines. The project applied innovative stimulation methods to improve well productivity, delivering measurable output improvements and demonstrating advanced well enhancement techniques in Philippine geothermal operations.
Geothermal Slim Well Testing — Armenia
JRG Energy designed, performed, and analysed the first-ever geothermal welltests in Armenia, combined with geological, resource, and geochemical data collection. The programme provided the first systematic characterisation of Armenia’s geothermal resources, establishing a foundation for future exploration and development.
Mineral Extraction Plant Study — Cerro Prieto
JRG Energy performed a silica extraction and mineral plant study and business plan at Cerro Prieto geothermal field in Mexico. The study assessed the technical and commercial feasibility of extracting silica and other minerals from geothermal brine, providing a business case for a co-located mineral extraction facility.
Technical Risk Review — Due Diligence
JRG Energy formed a multi-disciplinary team of specialised geothermal experts to perform a technical risk review and due diligence for a geothermal project in Ethiopia. The review assessed reservoir characteristics, development risks, and technical uncertainties, providing an independent evaluation to support investment decision-making.
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.
Well Testing — St Vincent Geothermal Exploration
JRG Energy performed geothermal well testing and wireline surveys on three exploration wells in St Vincent. Work characterised the geothermal resource potential of the wells, providing data on reservoir temperature, pressure, and fluid characteristics to inform the development pathway for St Vincent’s geothermal energy programme.
Geology Consulting and On-Job Training
JRG Energy provided geological consulting services for two UNEP ARGeo projects in Uganda and Tanzania. Scope included geological data collection, interpretation, and on-the-job training for local geoscientists, supporting the development of in-country expertise and contributing to regional geothermal resource assessments.
Geothermal Technical Assistance
Through NZ MFAT, JRG Energy provided managerial and technical capacity-building support to the Geothermal Development Company (GDC) in Kenya. Support covered operational guidance, technical expertise, and knowledge transfer to strengthen GDC’s capacity to develop and manage Kenya’s geothermal resources.
