St Vincent and the Grenadines: Confidence Shown in Improving Permeability at Geothermal Project

Permeability a continued challenge for SVG’s geothermal project (IWN)

After all testing, the well capacity will be known and the economic analysis updated, sometime around July 2020.

None of the three wells dug as part of the geothermal energy project have the level of permeability required although they have registered the temperature necessary for the production of electricity.

And Prime Minister Ralph Gonsalves told Parliament last Wednesday that “The conclusion in all of this as provided by the technical persons is that although the results in relation to the permeability have not gone favourably due to the very tight fractures that have limited the permeability, the tested temperatures on the wells were adequate for geothermal power,” Prime Minister Ralph Gonsalves told Parliament last Wednesday.

The prime minister said that the technical team will exhaust all options of well stimulation in an effort to open the fractures on the three wells and improve permeability.

He said that the technical team is optimistic that following the successful stimulation results of the well SVG 03, “they are hopeful that the others will be similar and in addition, strengthen the stimulation in 03”.
