Purpose of the drilling:
Thermal brine drilling on Rügen in Lauterbach, shaft with shaft equipment, conveyor system, electrical technology.
The thermal brine drilling was carried out using the air-lift drilling method with a drilling end diameter of 305 mm and a final depth of 700 m. After installing the pipe runs 508 mm Ø up to 99 m and 13 3/8″ up to 465.30 m below GOK including annulus cementation, the borehole was deepened to 700 m below GOK and expanded into a well. Winding wire filters with an outer diameter of 120 mm, GRP solid pipes 4 1/2″ and 5 1/2″ were installed and filled with filter sand from 700 m to 560 m below GOK and grouted with cement from 560 m to GOK.
