In June and July 1994, the hydraulic experimental programme consisted of a production test and an injection test at GPK1 ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK 1). During the production test in June, EPS1 ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-EPS 1) was used as injection well. A total of 6200 m3 of fluid were produced during the test. Then the injection test in July was intended to determine the injectivity of the stimulated fracture system as a function of the flowrate. A total of 9600 m3 of water were injected at various flowrates during the test (Baria, R., 1996.The European HDR programme 1992 - 1995).

Dates of the different tests of the 1994 hydraulic programme:

- Production test at GPK1: from 15:58 16/06/94 to 10:15 28/06/96

- Injection test at GPK1: from 11:06 05/07/94 to 14:56 13/07/96
