Wireline and Well Testing
JRG Energy provided wireline personnel and equipment to enable Mariott Drilling to perform geothermal wireline logging and well testing operations in Ethiopia. Services supported the characterisation of geothermal resources and contributed to the development of Ethiopia’s geothermal energy potential.
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.
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 […]
Montserrat Geothermal Well Testing Programme
JRG Energy developed and executed geothermal well tests on two wells in Montserrat for the island’s government. The full scope included front-end engineering and design, well test equipment procurement, wellbore simulations, programme development, geochemical sampling, and field execution — delivering a rigorous, independently managed testing campaign to characterise Montserrat’s geothermal resource for future development planning.
FRENZ — Caribbean Renewable Energy Programme
JRG Energy is a core delivery partner for the NZ-MFAT funded FRENZ programme supporting geothermal and renewable energy development across the Caribbean. Activities span geoscience studies, feasibility, drilling supervision, environmental planning, and capacity building. Countries supported include Dominica, Grenada, St. Lucia, and St. Vincent, with broader engagement across Belize, Guyana, Jamaica, and regional organisations including the OECS, CDB, and CCREEE.
DTS Fibre Optic Monitoring System Installation
JRG Energy was appointed to procure and install a Distributed Temperature Sensing (DTS) fibre optic monitoring system in the BO-2 monitoring well at the Bouillante geothermal field. The installation enables continuous remote monitoring of the downhole temperature profile and downhole pressure measurement via capillary tubing — replacing the need for regular PTS logging runs and […]
