TEP's Geothermal Analytics Approach Confirmed in Nevis by GeothermEx

March 20, 2018

TEP's Big-Data Analytics approach (that determined Nevis as a commercial-grade resource) was confirmed by Schlumberger-GeothermEx's team during a recently completed Geothermal Flow & Injection Test. As a result of this evaluation, Nevis' geothermal resource is being characterized as one of the top six geothermal reservoirs in the world that will not only provide resiliency and energy security to the island but have a greater impact for the rest of Caribbean as a whole. 

 

Nevis' reservoir quality was previously analyzed by TEP's team (led by Bruce Cutright) utilizing a Big-Data & Predictive Analytics approach that calculated the N-3 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 methodologyhas resulted in greater accuracy to calculate the potential of the island of Nevis. In other parts of the world, TEP's data-driven approach has resulted in an ever-expanding map of the earth's interior fluid that is much more widely available than previously thought. This methodology lowers risk and increases 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.
