GPK2 well

Description

GPK2 was the third well drilled for geothermal purposes at Soultz-sous-Forêts after GPK1 and EPS1. The well has been drilled southern to GPK1. It constitutes the second well of the doublet and obtains a maximum of fluid recovery. GPK2 well reached 3900 m in 1995 by drilling in destructive mode only. Hydraulic tests have been done to characterize the exchanger and to evaluate the potential fluid flow.
In 1999, it was decided to exploit a lower level at 5000 m depth, where the temperature reaches 200°C in order to develop a geothermal resource aiming at electricity production? GPK2 was then extended to 5084 m.
