KATI’s Sounding Hole for Geothermal Heat Plant

Finnish Energy company ST1 is developing a geothermal project in Espoo, Southern Finland and chose KATI as their cooperation partner. KATI drilling units can reach depths of more than 2,500 meters and we can offer core samples with a diameter of 30−80 mm.

A significant milestone for the project was achieved on 10th of July 2015, when KATI completed the borehole of 2,015 meter depths. It is called a sounding hole as there is a number of geophones "listening" while the actual production hole is being drilled, which gives the client a better understanding of the bedrock.
