Well Logging of 3 Geothermal Boreholes B3, B4 & UB1, Kollafjørður, Faroe Islands

Research output: Book/ReportReport (publicly available)


In the period 25 to 27 January 2016 GEUS carried out geophysical borehole logging in three geothermal boreholes in Kollafjørður, Faroe Islands (Figure 1-1). The investigations were carried out on behalf of Jarðfeingi (Faroese Earth and Energy Directorate), as part of groundwater investigations of the geothermal potential in the area.

The borehole logging was carried out in cooperation with Geo. GEUS complemented Geo’s logging program with a sonic-log of the formation velocity. This technical report follows the outline of the Geo report /1/.

The three boreholes are located about 25 km north of Tórshavn. Two of the boreholes are planned for extraction of geothermal energy for use in private houses (B3 and B4), and borehole UB1 is a research facility. The boreholes are around 200 m deep, where water temperatures of 25-27 degrees C have been measured, which is twice as high as the expected temperature at that depth /1/.
