Objective
To use geothermal energy to cover the heating requirements of a group of dwellings in the city of Lerida and of industrial/agricultural processes
According to the project design, a primary energy saving of 1,670 TOE/year is expected with a corresponding payback of 7 years.
The tarjet is the exploitation of two triassic aquifers (Muschelkalk dolomites and Buntsandstein sandstones), located between 1,100 m. and 1.250 m of depth.
If the short duration pumping tests on the dolomitic reservoir were not good enough, the drilling would continue so as to exploit also the lower sandy aquifer.
The expected reservoir characteristics are :
Flowrate : 100 - 150 m3/h; temperature : 60 deg.C.
It is not initially expected any reinjection plan, due to the low salinity of the water.
The main results did reveal :
- The existence of a modest aquifer
- The existence of lateral variation of transmissivity and the presence of an impermeable barrier simulated to be at 300 m.
The Lerida well exploitation has not yet started because competition with a new gas network. As a result, together with a geothermal water production less than expected on a modest aquifer, the economic conditions and the competitiveness of geothermal energy development have declined in the last two years, resulting from the abundant supply of conventional energy sources and their prices trends.
From these, and due to Enher has not got enough support from the Municipality and Regional Authorities, which have to play an important role in the development of project, has officially abandoned the project.
The production well was drilled to a final depth of 1,182.50 m, between June and August 1987. The reservoir extends from 1,116 to 1,169 m into dolomite (Muschelkalk) formation. At reservoir level, the well, drilled in 8 1/2 diameter, was left open hole without any completion.
The aquifer characteristics obtained during the logging, acidifying and washing phases were :
Productive levels, between 1,137 and 1,156 m.
Total productive thickness : 13 m.
Medium porosity : 12%.
Temperature at 1,119 m : 54.3 deg.C.
Salinity : 4,2
Maximum artesian flow-rate : 72 m3/h.
Based on the multi-step pumping tests, the following parameters
were deduced :
Storage coefficient : S = 6 x 0,0001
Transmissivity : T = 0,0001 m2/s
Effective well radius : R'w = 4 m.
Impermeable barrier = 300 m.
