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".

After the deepening of well GPK1 (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSF-GPK1) to 3590m in 1992, an extensive stimulation program was performed in September and October 1993. GPK1 was stimulated with large scale hydraulic injections to investigate the behavior and the extension of large natural fractures detected previously. A total of 44000 m3 of water was injected during the two major stimulation tests. About 18700 microseismic events were detected during the stimulation program by the downhole and the surface network. Dates of the different tests of the 1993 hydraulic program covered by the data*: - First openhole stimulation test at GPK1: from 01/09/1993 to 22/09/1993 - Packer test at GPK1: from 01/10/1993 to 05/10/1993 - Second openhole stimulation test: from 11/10/1993 to 21/10/1993 *Some other tests of less importance and not covered by the data of the episode were realized in 1993.

The 2004 stimulation was aimed at improving the hydraulic performances of the well GPK4 (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSF-GPK4). This borehole was stimulated twice. The 2004 episode corresponds to the first stimulation of GPK4. 9300 m3 of water were injected during the test at a constant flowrate of 30 l/s, with peaks up to 45 l/s. A low flow injection test of GPK4 was performed before the stimulation to evaluate the initial injectivity of the well. The data from the injection test are included too. Dates of the 2004 hydraulic programme: - GPK4 low flow injection: from 10:38 08/09/2004 to 10:00 12/09/2004. - GPK4 stimulation: from 08:32 13/09/2004 to 20:00 16/09/2004.
