Well logging

Ruden Geo Services is market leader in Norway concerning professional and commercial borehole logging (down to 3000 meters). We perform borehole logging in vertical holes, in boreholes and in horizontal holes. We have also developed methods for logging in horizontal wells that require water-filled holes.


Ruden Geo Services provides logging services to oil standards. Thanks to our close collaboration with EGS (European Geophysical Services) in the UK we have access to an extensive selection of instruments. All our instruments can be "stacked" to save time. The areas of application are e.g. feasibility studies for road or tunnel constructions, environmental studies and groundwater surveys and mineral exploration. Ruden Geo Services carries a wide range of probes for every imaginable purpose:
