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. Location GPK2 WGS84: Latitude: 48.9308924 | 48° 55' 51'' N Longitude: 7.86662988 | 7° 51' 59'' E

GPK1 was the first well drilled for geothermal purposes at Soultz-sous-Forêts. The well was first drilled in 1987. It reached 2000 m and the temperature at the bottom hole was 140°C. Several hydraulic injections have been done associated with tracer tests and temperature and flow logs. In order to get deeper information, the GPK1 well was deepened to 3600 m in 1992. The downhole temperature reached 160°C. Location GPK1 WGS84: Latitude: 48.93525543 | 48° 56' 6'' N Longitude: 7.86535117 | 7° 51' 55'' E

The 2010 circulation test began in November 2009 after a maintenance period and lasted until October 2010, when a new maintenance period was programmed. This 11-month experiment is the longest circulation ever performed on the Soultz project. During the test, GPK2 was used as production well (with Line Shaft Pump), GPK3 and GPK1 as reinjection wells (Cuenot, N., Genter, A., 2015. Microseismic Activity Induced During Recent Circulation Tests at the Soultz-sous-Forêts EGS Power Plant). The Episode contains several datasets which you can find further down the page in "Links".
