Geothermal test well confirms sustainable energy reservoir
From the NIA
CHARLESTOWN, Nevis – A GeothermEX team from the United States of America (USA) contracted by the Nevis Renewable Energy International (NREI) to determine the status of the geothermal test well at Hamilton says its findings confirm the requisite temperature and flow necessary for a sustainable supply of geothermal energy on Nevis.
Robert Stacey, senior reservoir engineer with the team, said March 16 the resource looks promising.
“We are with the well flowing very nicely,” he said. “High temperatures coming along and plenty of steam coming up from the resource. Very excited to see this. Plenty of energy has gone into this project to achieve what’s culminating here today. Very happy to be here to make this become a reality.
“The resource so far looks very promising. High temperatures down at resource at commercial grades to produce power. Right now, we are preparing to go in and measure those to quantify how much resource it is and how best to develop the resource here,” he said.
GeothermEX is a subsidiary of Schlumberger Company, the largest oil field testing company in the world. However, GeothermEX focuses specifically on geothermal energy testing.
As of March 19, the tests results at Hamilton continue to hold steady, with surface reading temperatures of 255 degrees Fahrenheit; steam temperatures of 411 degrees and well temperature readings of more than 400 degrees.
An elated Bruce Cutright, chief executive office of NREI, says they have waited, on behalf of the people of Nevis, for five years to get to the well testing stage. He described the project as a difficult, yet rewarding one.
“It has been a tough project to work on,” he said. “We know that the people of Nevis have been waiting 10 years to see this flow rate that is behind us. This will transform the island.
“This is the most exciting test that you could imagine. You could see the steam behind us is flowing at a rate [that] demonstrates to us that this is a commercial scale geothermal reservoir that is beneath the island of Nevis. This will supply the electrical energy needs for the entire island. So, we are very pleased to see this. Again, long road to get here, but this is the success story that you see with the steam coming off the reservoir,” he said.
Cutright added that the testing operations at Hamilton are completed. Though the drilling plan was to go to 4,000 feet, they entered the geothermal reservoir before the. The reservoir has a capacity exceeding 5 megawatts of energy and drilling for the production wells on the site is expected to begin late this summer.
Mackie Tross, NREI’s local representative, was also present. He said he was excited that they had arrived at a two-phase system producing both water and steam and is looking forward to the geothermal project becoming a reality.
NREI was contracted by the Nevis Island Administration some time ago to harness the island’s geothermal energy.
