New details provided in a project update for the Montserrat geothermal project are promising, as they indicate higher temperatures and better permeability of the third well now being drilled on site on the island.

In a new update on the drilling activities for the Montserrat geothermal project in the Caribbean, Nicólas Reyes, the Project Manager for the project, provides some very positive news.

During last week an additional 600 meters have been drilled since the last update … from 1,600 to 2,200 meters. The drilling identified the productive zone and increased geological knowledge for the project. Analysis of core samples will now be conducted in the UK.

At 1,700 meters a temperature log was carried out, confirming hot temperatures and suggest a very promising 250 degrees Celsius at this depth .. at 1,708 meters it was decided to apply a mud motor to improve bot drilling velocity and  to control the angle of the well … decision to incline the drilling direction 20 degrees with the aim at intercepting previously identified features. Permeability … a major loss was encountered at 2,174 meters, meaning a major fracture zone has been intercepted and permeability is likely greater than the first two wells drilled for the project.

So overall the recent results are very promising for the project.
