A 2,5 km deep borehole was drilled in Åre (Sweden) with the purpose of understanding how major mountain belts of Alpine-Himalayan dimensions developed over a period of 500 million years. CMR’s part in the project was to provide advanced fibreoptic distributed temperature sensing.

CMR has delivered fibreoptic distributed temperature sensing to an international scientific deep drilling project, resulting in an impressive accuracy of 0.1°C and a spatial resolution of less than 0.5 m.
