Geothermal Well Maintenance and Capacity Building
JRG Energy was contracted by the Government of Montserrat to maintain the integrity of the island’s geothermal wellhead equipment and build in-country operational capacity. The scope covered well maintenance operations, technical support to local staff, and knowledge transfer to ensure the wells remain in a safe and operable condition.
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.
Well Test and Intervention Training
JRG Energy trained EDC geothermal operations personnel on well testing, well intervention, PTS data quality, and related operational procedures. The programme built in-house capability within EDC, covering both theoretical knowledge and practical skills to support safe and effective well operations across EDC’s geothermal portfolio.
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.
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.
Wireline Fishing Operation
JRG Energy was contracted to fish tools lost in a large geothermal production well in the Philippines. The work required specialist downhole fishing expertise to retrieve lost-in-hole equipment, restoring wellbore access and avoiding the need for costly remediation or abandonment.
Coil Tubing Scale Removal Campaign
JRG Energy successfully launched an innovative coil tubing scale removal campaign in the Philippines. The programme addressed scale build-up across the PGPC well portfolio, with JRG providing engineering design, equipment sourcing, operational supervision, and technical expertise to restore and enhance well productivity.
Slickline and Wireline Training Course
JRG Energy was contracted to teach a slickline and wireline course for thermal well testing to EDC Philippines operations personnel. The course covered equal parts theory and practical technique, building operational capability for wireline logging, tool operation, and data acquisition in high-temperature geothermal wells.
Coil Tubing Scale Removal
JRG Energy worked with Energy Development Corporation (EDC) in the Philippines to execute a coil-tubing scale-removal campaign. The project targeted scale build-up in geothermal production wells, with JRG providing technical expertise and operational support to restore well productivity and extend asset life.
