Journal Article: The Geothermal Potential Of Salt Structures In Northern Germany

Abstract
Temperature fields of the salt diapirs Taaken, ScheeBel, Wedehof, Ostervesede and Sohlingen as well as the salt pillows Rotenburg and Ludingen in the region of Rotenburg (Wumme) were determined on the basis of temperature data from hydrocarbon wells The focussing of the heat flow in the Zechstein salt results in zones with different utilisation properties for a potential geothermal exploration. Temperatures in the salt diapirs and the overlying strata are increased up to a depth of 2500 m compared to the proximal environment The values are increased at an average of 10 to 15 degrees C in comparison to the local temperature The maximum positive anomaly is 24 degrees C. The increased geothermal potential can be developed with shallow, medium and deep geothermal probes The local hydrogeological conditions can enhance the utilisation potential at a shallow exploitation Positive temperature anomalies have also been observed above deep salt pillows. Temperatures are increased to a depth of 4000 in compared to the surrounding rocks The temperature plus is frequently in the range of 10 degrees C. The potential above deep salt pillows can be developed by geothermal probes or geothermal doublets
