The Geological Survey of Norway (NGU) requests additional knowledge on cracks and hydrologic flows in Norwegian crystalline rock types, with a particular focus on increasing the knowledge of the connection between tectonics and cracks in different rock types along the Norwegian beaches in the western and central parts of Norway. In order to achieve this NGU is planning to carry out core drilling for minimum four (4) 100 metre deep drilling holes with a diameter of minimum 96 mm. The core drilling shall be executed in Smøla and Bømlo.

NGU shall implement petrophysical logging and water flow measurements for all drilling holes. In case of technical or geological problems during the drilling, NGU and the contractor shall decide if the water flow measurements shall be implemented simultaneously with the drilling prior to the potential casting.
