Daldrup & Söhne AG has received a drilling contract value at around $21 million to drill two wells for the Geretsried geothermal power project in Bavaria, Germany.

Germany-based drilling company Daldrup & Söhne AG announced that it has secured a new drilling contract from the Geretsried geothermal project of Enex in Bavaria, Germany. The contract as a value of around EUR 19 million ($20 million).

This project is unique as it is the first project in Germany, where Daldrup is implementing an integrated insurance model that has already been successfully deployed abroad in order to hedge exploration risk. In cooperation with the research project “Dolomitkluft” of the German Federal Ministry for the Economy, the 6,186 meter long bore, which has reached a temperature of 160 degrees Celsius but has not found sufficient depth of groundwater, is to be made economically viable.

For this purpose, a sidetrack is to deviate off from the existing main borehole and connect it to the geothermal reservoir via a modified drilling path up to 5,700 m. A second hole is to open the reservoir at a depth of 4,900 m. T

The geological and seismic preliminary investigations as well as the insights gained from the drilling drilled in 2013 show structures which allow an adequate water quantity (bed) to be reached in addition to already secured temperatures of 160 degrees Celsius. If such a liquidity exists, the customer plans the erection of a geothermal power plant.

Daldrup also announced having been commissioned for the drilling of a well to a depth of 1,200 m for a geothermal spa operation in Bad Bellingen in Germany. The total project cost by the client is estimated at EUR 3.8 million.  The well produces around  hot water with a temperature of 70 degrees Celsius, which is then provided to the Bad Bellinger thermal baths. The residual heat is to be used for the heating of another thermal spa, thus reducing energy costs.
