Coil Tubing Scale Removal


JRG Energy successfully launched an innovative Coil Tubing-Scale Removal campaign in the Philippines. This included sourcing equipment, designing specialized equipment, managing logistics/customs, implementation and engineering, commissioning equipment, managing multiple international sub-contractors, COVID-19 quarantines, and more to achieve results. Highlights on the first well include milling with an industry first all metal-motor in +250 degC environment with an average ROP of 37m/hr, utilizing high-temp air hammers with customized bits, and engineering equipment modifications to improve the efficiency of subsequent campaigns.  



Technical Risk Review


JRG Energy formed a multi-disciplinary team of specialized geothermal experts to perform a due diligence, gap analysis and technical risk assessment for MIGA (insurance arm of the World Bank) regarding the Tulu Moye Geothermal Project in Ethiopia. The team analysed all reports and data provided for the client to generate two technical risk reviews and reported findings.



Wireline Fishing


JRG Energy was contracted to fish tools lost in a large geothermal production well. The work was performed in collaboration with the GREG team of EDC to remove tools successfully using slickline techniques.

Well Test & Intervention Training


JRG Energy trained EDC geothermal operations personnel on geothermal well testing, well intervention, PTS data quality assurance, tracer flow testing, and design and installation of chemical inhibition system.



Well Testing

St Vincent, Caribbean

Performed geothermal well testing and wireline surveys on 3 geothermal exploration wells in St Vincent, Caribbean. JRG managed all site tasks including procurement of wireline equipment and operating equipment on-site for surveys/well tests.



Well Testing & Procurement


JRG Energy assisted the lead technical adviser to Electric de Djibouti (backed by the World Bank) to drill, test and eventually produce the Fiale geothermal resource in Djibouti. JRG Energy is assisting the client by providing well test equipment, performing the well’s geothermal wireline surveys and well testing.

Asset Inspection

New Zealand

JRG Energy's sister company, Aerosphere Inspection, was contracted to perform an asset inspection and 3D model creation of an off-shore oil production platform.  The team used UAVs with various cameras and sensors to collect data from the structure to generate a risk/inspection report. The images were also combined to create a comprehensive 3D model which was used in a virtual reality VR/AR platform.

Geothermal Well Enhancement


JRG Energy worked as part of a team that introduced and executed a reservoir enhancement technique regarding calcite and silica removal using slickline broaching and acidizing with capillary tubing.  The project was done in partnership with SGS Philippines and Australasia.  JRG Energy has been engaged in this project for over 2 years and is still ongoing.

Q1 2019


Capillary Tubing Installation


JRG Energy designed and installed a capillary tubing system for geothermal production wells at Cerro Prieto. The system was installed, tested and replicated in 19 different wells across the field to mitigate silica scaling and corrosion due to acidic wells.

Instructional Course


JRG Energy was contracted to teach a slickline/wireline course for geothermal well testing. The course consisted of equal amounts of classroom theory and site demonstrations to teach scale removal, fishing and safety procedures.



Direct-use Feasibility Study

New Zealand

JRG Energy performed a desktop study for a dairy client to asses the feasibility of utilizing existing geothermal assets for their dairy pasteurization process. The study included technical review, engineering practicality and previous case studies to create multiple business cases for the client to consider.

Well Stimulation and Perforation

New Zealand

JRG Energy was the site manager/supervisor for all 3rd party contractors used to perform a multi-stage well stimulation (frac) on a large production field. The project included supervising main industry contractors (Halliburton, SGS, Schlumberger) to optimise the efficiency of the operation and ensure everyone complied with technical procedures, HSE, protocol, and environmental regulations.


Geothermal Well Test Survey

General Well Services

New Zealand

JRG Energy lead operations for Implementation testing and data acquisition essential to the development and implementation of a reservoir management strategy for geothermal fields operated by power generation companies in New Zealand.
