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.
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.
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.
High-Temperature Packer Deployment
JRG Energy provided high-temperature equipment procurement, engineering services, and operational support for a packer deployment programme in Indonesian geothermal wells. The project required specialised tools rated for high-temperature and high-pressure downhole conditions, with JRG managing full procurement and operational execution.
Scale Removal and Production Enhancement
JRG Energy worked with the Philippines Geothermal Production Company to manage a slickline well intervention campaign targeting scale removal and production enhancement. Operations addressed scale deposits restricting production with the aim of restoring and improving well output across the affected well stock.
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.
Scale Broaching Campaign — Mak-Ban and Tiwi
JRG Energy mobilised at short notice to execute a challenging broaching campaign across six wells at Mak-Ban and Tiwi. Several wells were fully plugged, requiring coiled tubing and rig milling interventions. JRG demonstrated full wellbore access to TD on some wells, recovered one well to production for the first time in 12 years, and made significant broaching […]
