Coil Tubing Scale Removal

Philippines

JRG Energy worked with the local Philippines geothermal company, Energy Development Corporation (EDC) to manage a coil tubing well intervention campaign for 2 x major production wells. The project consisted of pre-job planning and engineering, procurement of specialized tools, site supervision, training, and reporting. The results produced over 7 additional MW across the two wells.

Coil Tubing Scale Removal

Philippines

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.

Drone Rig Inspection web.jpg

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.
