Objective
A first well realized in 1995 to produce water from Neocomian sand formation-lower cretaceous give clear indication of the importance of this water table on quantity and qualify as well as mineral as geothermal (150 m3/h at 38.5 deg. C at the head of the well). A second well planned in 1997 is necessary to provide process needs. The installation of a heat pump will allow to improve the utilisation of the geothermal energy.
The production of both geothermal wells will represent an instantaneous thermal power of 11 MW thermic for a cold water network of 6 deg. C reference temperature.
This heat pump project will allow the valorisation of a parisian basin intermediate sheet of water.
The innovative character of this project lies in the use, as geothermical fluid, of soft water from a water-bearing bed, with a very low mineralization and a drinkable quality. The Neocomian water satisfies one and the same time to industrial water needs, and factory energetical needs too. This double employment contribute to the improvement of the project global profit-earning capacity. Two wells, distant of one kilometer and one thousand meters deep, equipped with two immerged pumps will give respectively 150 m3/h, 300 m3/h both. Pipes will connect wells to an existant water treatment plant. Since this technical center, a pipes network will connect the heat pump to be built. Through thermal exchangers, the drilling water will abandon a part of its thermical charge from 38.5 deg. C to 23 deg. C, that a heat pump will transfer to a 60/85 deg. C industrial hot water network.
