Objective
To use geothermal water for thermal spa applications and sauna in a recreational resort centre to be built in Weiden. The reservoir at 1300 m depth is made of detrital formations overlying granitic and gneissic basement.
Expected flow rate is about 18 m3/h of drinking water at 35 deg. C.
Water will be treated and filtered before use in baths to avoid Fe and Mn oxydes.
Well drilling will be realized close to the resort site to have the shortest distribution network possible.
This project encountered difficulties when the drilling crossed an hydrocarbonaceous zone. (0,4 m3 of oil has been produced). This problem led the operator to cement the lowest part of the drilling and to produce water from a shallower reservoir with both low temperature and flowrate. The well is exploited at 6,5 m3/h - 23 deg. C. The discharge temperature is 14 deg. C and the power of 106 kWht. Annual energy savings expected are 65 TOE.
The well was drilled to a final depth of 1459,75 m between November 88 and September 89. It was fitted with 7 5/8" casing down to 960 m.
Two sections (583 - 797 m and 851 - 941 m) were left free from cementation for later tapping measures (perforation). At a depth of 1230 a hydrocarbonaceous zone has been struck. Oil tests and loggings were done and the cored interval for the installation of casing had to be enlarged. After completion of the oil tests the oil bearing zone has been sealed by installation of a 159 mm casing down to 1224 m. Mud loss occurred between 1309 and 1319 m and between 1383 and 1389. Pumping tests in the open hole showed a flowrate of 0,05 l/s at 150 m depression. To get a sufficient output higher aquifers (857-933 m and 608 - 753 m) were tapped by perforation.
Long time pumping tests were carried out (November, December 1990) out and showed an output of about 7,2 m3/h at about 23 deg. C.
