Drilling of a 200 meter deep energy well in the central parts of the small town of Söderköping, Sweden. The contractor, Finspång Brunnsborrning AB, chose the water powered Wassara W100 hammer instead of pneumatic technology. The reason was the potentially greater risk of damaging nearby buildings when using a pneumatic hammer compared with the Wassara hammer. Casing drilling was performed for the first 60 meter with Wassara W100 and Tubex.
Result:
Finspångs Brunnsborrning AB successfully carried out the drilling operation without causing any damage to surrounding buildings.
