Ruden AS was founded in 2007 by hydrogeologist Fridtjov Ruden. Over the years Fridtjov and the rest of our team has found water on land, in deserts, under the oceans and in about 25 countries all over the world. We have developed new search models for water in unlikely places and recieved several prestigious innovation awards in the process.Ruden AS are developing groundbreaking geophysical techniques for subsurface exploration of water and minerals.
