Energy Drilling with W100 in Danderyd, Sweden

Drilling of two energy wells for a private house in Danderyd outside Stockholm, Sweden, in November 2001. Each well was drilled to 180 meter. Due to large influx of water in the wells pneumatic drilling was out of the question and Wassara W100 Drilling System was the only solution. This project also provided an opportunity for one of the first trials with Wassara Production Unit (WASP). The work was carried out by Sven Andersson Brunnsborrning Uppsala AB.

Result:

With the Wassara Drilling System the large influx of water presented no problem and the wells could be drilled successfully to the required depth.
