Balneology Bad Wörishofen

Thermal water is essential for the health resort Bad Wörishofen in South-East Bavaria. To meet the growing demand by the thermal bath, the town of Bad Wörishofen decided on a new thermal well in 2004, right next to the existent thermal bath.

Between May and June 2005, the drilling site was prepared and on June 30th, 2005 the drilling company Geomechanik from Woringen started the drilling operation. After about 850m the drilling rig was exchanged and the company HAS from Hessisch-Lichtenau completed the deep drilling sections (section 2 with a drill diameter of 8.1/2" and section 3 with a drill diameter of 6.1/8"). On October 9th, 2005 the well Wör GT2 finally reached the target horizon in the Malm deep aquifer at depths of 2600m.

During a pump test with air lift system, the well was cleaned first and then tested for its water yield potential. With the following long term pump test and pilot phase, the sustainability of the well capacity could be confirmed.

The local geothermal conditions turned out to be very positive. At a relatively low flow rate during the long term pump test of 5 l/s temperatures of about 80°C could be measured at the wellhead. This temperature is significantly higher than originally expected. The thermal water is of course cooled down to a comfortable bathing temperature before being fed into the pools.
