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.

Roseau Valley Geothermal Project

JRG Energy mobilised wireline personnel and equipment on short notice to support Iceland Drilling’s geothermal drilling programme in Dominica. The scope covered equipment procurement, downhole PTS data acquisition, wireline logging and well test management, reservoir and geochemical data analysis, and professional reporting — enabling IDC to fully characterise the Roseau Valley geothermal resource in support of Dominica’s […]

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 […]
