The borehole KH-08-12 was drilled in August/September 2012 by Geo Drilling and the logging was executed in March 2013 by the Geological Survey of Norway (NGU). The borehole is located at WGS-84 6895850N 395400E zone 32W and ca. 735 meters above sea level, at the upper western part of the Åknes rock slope. The drill cores are logged with regards to bedrock type, fracture frequency and zones of interest with respect to sliding plane(s).
This drill hole is the first at Jettan in the Nordnes mountain, named NN-01-12. The borehole was drilled during summer/autumn 2012 by Arctic drilling and the drill core was logged at the Geological Survey of Norway (NGU) in May 2013. The cores are now stored at Løkken drill core and rock sample storage at the NGU. The drill core is approximately 200 metre long (198.8 m) and due to fracture and/or fault zones the drill hole was cemented and re-drilled several times to keep stable.
The project's aim is to achieve a better understanding of shallow geological/seabed conditions and processes to support technical and environmental aspects of exploration and production along the southwestern margin of the Barents Sea, including the Hammerfest Basin, the Loppa High, the Polheim Subplatform, the Tromsø Basin/lngøydjupet area and along the Finnmark Platform.
The Mofjell project commenced in 2008 as a cooperation between GEXCO Norge AS, the county administration of Nordland and NGU. As GEXCO faced financial difficulties the external funding ended in 2009. The project area included Mofjellet and the eastern part of Plurdalen, an area with a large potential for economic sulfide deposits with Zn, Cu, Pb, Ag and Au. NGU has focused on establishing the geological setting of the Mofjell Group and its relation to ore formation.
In 1996, the Geological Survey of Norway started the project "Fracture zones and groundwater of Sunnfjord". The aim of the project was to get a regional understanding of deformation along bigger post-Devonian lineaments/fracture zones in crystalline rocks, and the relevance of these lineaments in connection with well capacity. This report presents results from the tracer tests, borehole tomography and electrical conductivity profiles conducted in September 1999.
The Geological Survey of Norway has compiled an inventory of hard rock aggregate deposits in coastal Norway. This report contains a catalogue of Norwegian coastal quarries presently in production and exporting, as well as of potential production areas along the coast of South-Central Norway and Finnmark. In 2012, 22.6 million tonnes of aggregates were exported to Europe, and about 6.8 million tonnes were used by the offshore oil and gas industry on the continental shelf.
Sandwaves are common on many continental shelves indicating erosion, transport and deposition of sand by bottom currents. Their dynamic nature means that they can pose challenges to seafloor installations such as pipelines and other constructions on the seafloor. For studies of pollution and seabed resources (biological and geological) it is necessary to know where erosion and seposition occur.
66 ustabile fjellpartier er undersøkt i løpet av feltsesongene 2011 og 2012. 45 av de ustabile fjellpartiene er feltbefart for første gang av geologer fra NGU, og 19 av disse er avskrevet som ikke ustabile fjellpartier. De resterende ustabile fjellpartier har enten blitt kartlagt ytterligere, eller det har blitt utført ren datainnsamling uten videre kartlegging.
