Episode: 1996 Stimulation and Hydraulic Tests Soultz-sous-Forêts

A series of hydraulic tests were performed from August to October 1996 at the GPK2 well ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK 2). First a production test was conducted in August to determine the productivity of the well. The production test was followed by a second stimulation of GPK2 after the previous one in 1995. The open hole section of the well was re-stimulated at flowrates up to 78 l/s. A total of 28000 m3 of fluid was injected during the test. The stimulation was followed by a stepped injection test to determine the injectivity of the well after the stimulation. Finally, two circulation tests during which the water produced from GPK2 was reinjected in GPK1 ( https://cdgp.u-strasbg.fr/geonetwork/srv/fre/catalog.search#/metadata/SSF-GPK 1) were performed in October 1996. About 7500 microseismic events were detected during the experiments, and about 5700 were located.


Dates of the different tests of the 1996 hydraulic programme:

- Production test at GPK2: from 09:20 14/08/96 to 03:40 15/08/96

- Stimulation test at GPK2: from 16:30 18/09/96 to 22:15 25/09/96

- Stepped injection test at GPK2: from 10:30 29/09/96 to 04:00 06/10/96

- First circulation test between GPK2 and GPK1: from 10:04 12/10/96 to 12:09 20/10/96

- Second circulation test between GPK2 and GPK1: from 15:30 28/10/96 to 19:10 30/10/96
