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. Details about these tests are available in Baria, R., 1996, The European HDR programme 1992-1995.
