Obiettivo To use geothermal energy to provide all of the heating requirements for one Ha of greenhouses. If this pilot stage is successful the project will be expanded to 5 Ha. It is estimated that a primary energy saving of 300 TOE/YR will be achieved with a corresponding payback period of 5 years.The geothermal potential of the REUS-RONTBRIO zone appears to be as expected. The down hole temperature of 60 deg.C at 200 m depth indicates a high temperature gradient. However the diameter of the exploratory well was not sufficient, and the depth too shallow, to carry out a full evaluation of this promising geothermal field.(Brian's note: I see that one of your keywords is Piezoelectricity. This is not the same as Piezometric which means to measure pressure or compressibility. Piezoelectricity is a voltage generated as a result of pressure in a crystalline substance. Of course I dont't know how the measurements are done. Maybe they use piezoelectric crystals (but I doubt it).)Two wells are planned, one for production and one for piezometric control, to exploit a shallow hydrothermal resource lying at depths varying from 50 to 400m. This geothermal water has a low salt content allowing its possible use as a water supply after heat extraction. A water temperature of between 30 and 80 deg.C is expected with a flow rate of 100m3/h.The geological conditions in this area are similar to those in another project supported by the Commission in Cataluna (see GE/523/86/ES).The piezometric well has already been finished. It is 603 m deep and water at 68/70 deg.C has been obtained and the airlift results show a satisfactory hydraulic performance. As a consequence of this piezometric well, a production well is proposed with filters at 500/700 m. The planned site is at a distance of 300 m North-West of the piezometric well where, according to the studies, a granite region with lower depth and higher temperature and permeability should be situated.
