Abstract
Two geothermal power projects were undertaken in 1976 in southwestern France, coming into production in 1977. They extract the heating energy from fresh water at approximately 60°C, without reinjection, from two different natural reservoirs : karst limestones or conglomeratic sandstones between 1850 to 1600 m deep. The two wells also correspond to two different types of application: supplying several consumer previously equipped with conventional heating plants : military base, residential and hospital; supplying a vast residential complex preequipped with a view to use of geothermal energy.
