Denne rapporten gir en oversikt over de viktigste kalksteinsprovinsene med tilhørende forekomster innenfor GEOS-området. Det er 4 områder med forekomst av kalksteiner der det har vært drift tidligere: Totenområdet, Lunnerområdet, Oslo-Drammen-Holmestrandområdet og Skien-Langesundområdet.
Thermal response tests (TRT) are widely used to measure the effective thermal conductivity and borehole resistance in a well. The gained data serve as the basis for the dimensioning of larger ground-source heat-pump installations with closed loop systems. The influence of groundwater flow on a TRT in fractured aquifers is not well understood. An attempt to quantify the influence of groundwater was done by pumping of groundwater from a nearby well during the TRT.
During June, 1997, a helicopter geophysical survey was carried out over part of Nordmarka, an area immediately northwest from Oslo. The purpose of the survey was to provide geophysical information to improve geological mapping in the area. Approximately 3260 line-kilometers of VLF, radiometric, magnetometric, and electromagnetic data were acquired, covering an area of approximately 650 sq km, mostly over the area covered by NGUs Oppkuven mapsheet.
