Nevis’ Geothermal Resource Considered Among the Best in the World

The official results are in and the Nevis’ geothermal resource is now being characterized as one of the top six geothermal reservoirs in the world. The implications of will not only provide resiliency and energy security to the St. Kitts and Nevis this will have a greater impact for the rest of Caribbean as a whole. Prior to the actual flow test results, Nevis’ geothermal resource was originally characterized through a Big-Data Analytics approach that estimated  the resource to be commercial-grade quality. This week those previous estimates were confirmed by a GeothermEx’s team during a recently completed Geothermal Flow & Injection Test.

TEP’s team (led by Bruce Cutright) made estimates last year using a Big-Data & Predictive Analytics approach to calculate the site could supply a minimum of 10-12 MW per production well as opposed to earlier industry estimates that only estimated 3-4 MW per well. TEP’s process that utilizes approaches from the Oil & Gas industry has resulted in transforming the way the geothermal industry can calculate resources for long-term sustainability. TEP’s approach has shown to be more accurate and can save up-front capital that is usually associated with geothermal exploration. Today’s 3rd-party confirmation by Schlumberger’s GeothermEx team confirms the previous calculations made by TEP regarding the island’s potential geothermal reservoir quality.

GeothermEx says its findings confirm the requisite temperature and flow necessary for a sustainable supply of geothermal energy on Nevis and the reservoir has been classified as high-grade commercial quality.

During the injection test (to test the level of permeability) the team  encountered no resistance indicating an extremely permeable and large reservoir. Temperatures were recorded at 492F (255 C) at a depth of approximately 3,000’ and the company anticipates drilling the production wells to 4,000’.

When compared to the traditional “hot-spot” geothermal methodology that estimates resources through the use of only a test well, TEP’s predictive analytics methodology has resulted in greater accuracy to calculate the potential of geothermal and is transforming the industry. When TEP’s data-driven approach is applied, this has resulted in an ever-expanding map of the earth’s interior fluid that is much more widely available than previously thought, thus bringing the possibility of geothermal electricity to more locations around the world with lower risk and greater accuracy. For St. Kitts and Nevis, TEP’s team predicted a very high-grade of commercial quality resource that not only can be used as base-load electricity for Nevis but can be exported to other islands.
