St. Vincent Geothermal Project: Drilling Update

Since the geothermal drilling in the Caribbean island of St. Vincent and the Grenadines kicked off in May 2019, two exploration wells have been drilled with the third currently in the active drilling phase.

The aim of the project is to deliver 10 MW of geothermal power to the island of St. Vincent, with the drilling program expected to be completed in early 2020, testing in March 2020 for a concrete estimation of production capability, and then go to the market for plant design by August/September 2020. Plant construction is estimated to start in late 2020 or early 2021.

The second well has seen some positive results and has responded positively to well stimulation. The well indicates a temperature of above 220 degrees Celsius and will continue to be stimulated to further open the fractures as the drilling of well three is underway.

The initial well reached a length of 2,700 m, but with limited permeability encountered. As the well collapsed in the last 1,000 m section it was not possible to perform a well stimulation program. The well has potential temperatures likely over 220 degrees Celsius and will be repaired once the drilling program is complete, in early 2020.
