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.

During February/March 2005 a hydraulic stimulation program was conducted in the well GPK4 (https://cdgp.u-strasbg.fr/geonetwork/srv/eng/catalog.search#/metadata/SSF-GPK4) at European Hot Dry Rock Project, Soultz-sous-Forêts, France. It is the second stimulation of GPK4, after the previous one, performed in September 2004. The hydraulic stimulation was followed a few days later by a program of chemical stimulation (injection of diluted HCl). This program involved the chemical stimulation itself and two identical step-rate injection tests. The first injection test was performed before the chemical stimulation and the second after, in order to observe the efficiency of the chemical stimulation. Dates of the 2005 hydraulic programme: - Second hydraulic stimulation of GPK4: from 18:05 07/02/2005 to 18:00 11/02/2005. - First step-rate injection test of GPK4: from 15:30 22/02/2005 to 15:30 25/02/2005. - Chemical stimulation of GPK4 with HCl: from 13:30 02/03/2005 to 06:00 05/03/2005. - Second step-rate injection test of GPK4: from 10:00 13/03/2005 to 09:55 16/03/2005. 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.
