Objetivo
Utilization of an existing wild cat recovered for geothermal application (Greenhouses) with EEC support (see GE/50/81/FR). The 200 m3/h geothermal water flow at 75 deg. C will be used to heat the water of the ponds allowing breeding of 10 T of eels and 20 T of sturgeons. A new work over of the well with realization of additional seals and stimulations would increase the natural artesian flow rate from 130 to the required 200 m3/h with a well head pressure of 3 Bars. The geothermal water will be transported to the plant (660 m) and after cooling via a plate heat exchanger discharged to the nearby coastal river.
The project is completed. The first tests indicate a performance corresponding to the feasibility studies. The fishfarm will produce only sturgeons and the annual energy saving would reach 3200 TOE.
The water coming from the river "La Leyre" is heated by the geothermal water at 75 deg. C via a plate heat exchanger. The well tests performed by BRGM in 1990 have demonstrated a 200 m3/h assisted flow rate.
The perennity of the geothermal resource is proved because the well has been producing since 1984, 130 m3/h by artesianism.
The project GE/00047/89/FR corresponds to the surface equipments of the geothermal loop (piping, plate exchanger, monitoring equipment..).
The project GE/00063/91/FR deals with the subsurface equipment including submersible pump variator and auxiliaries.
The fishfarm itself has been constructed by a private company "l'Esturgeonniere" with the support of the DDA (Direction Departementale de l'Agriculture).
The geothermal loop (subsurface and surface equipments) has been installed in July-August 1992. The hydrodynamic conditions in the well while pumping are as expected and the whole installation including the fishfarm put into operation during August.
