Episode: 1995 Stimulation and Hydraulic Tests Soultz-sous-Forêts

Collection

The 1995 hydraulic program tested GPK‑2 and its ability to circulate with GPK‑1. After low injectivity was confirmed, short‑ and long‑term stimulations were performed, followed by post‑fracturing tests and three brief circulation experiments between the two wells.

Episode: 2003 Stimulation Soultz-sous-Forêts

Collection

The May–July 2003 hydraulic programme at GPK‑3 involved an 11‑day deep stimulation injecting 34 000 m³ of water (including an initial 450 m³ brine slug), followed by a 17‑day post‑stimulation circulation test between GPK‑3 and GPK‑2. Microseismic monitoring continued throughout the operations until late August, capturing the system’s response across five distinct hydraulic phases.

Episode: ECOGI geothermal project at Rittershoffen - development phase

Collection

The ECOGI geothermal plant in Rittershoffen has operated since 2016, supplying 24 MWth of heat at 170 °C to a nearby biorefinery. Its development (2012–2014) involved drilling GRT‑1 and GRT‑2, during which induced seismicity was recorded by permanent and temporary networks.

Geological sections from GeORG-Rittershoffen

Dataset in collection Episode: ECOGI geothermal project at Rittershoffen - development phase

The GeORG project (2008–2012) built a 3D geological model of the Upper Rhine Graben, offering maps and cross‑sections accessible online. A subset around the Rittershoffen site was extracted for use.

Hydraulic data - Soultz-sous-Forêts 1995 Stimulation and Hydraulic Tests

Dataset in collection Episode: 1995 Stimulation and Hydraulic Tests Soultz-sous-Forêts

Hydraulic data from GPK1, GPK2, and EPS1 were recorded during the 1995 stimulation, injection, and circulation tests at Soultz‑sous‑Forêts. The datasets cover June to August 1995, including surface flowrate/pressure/temperature series and downhole measurements in both GPK1 and GPK2 during stimulation phases and the three circulation tests.

Microseismic catalogue of the downhole network from CSMA - Soultz-sous-Forêts 1995 Stimulation and Hydraulic Tests

Dataset in collection Episode: 1995 Stimulation and Hydraulic Tests Soultz-sous-Forêts

This catalogue lists 5295 microseismic events recorded at Soultz‑sous‑Forêts during the 1995 stimulation, injection, and circulation tests. It provides event times, local coordinates relative to GPK1, and derived WGS84 locations. 3636 events overlap with another 1995 catalogue, with location differences due to different relocation models.

Microseismic downhole network - Soultz-sous-Forêts 1995 Stimulation and Hydraulic Tests

Dataset in collection Episode: 1995 Stimulation and Hydraulic Tests Soultz-sous-Forêts

The 1995 microseismic network used three downhole accelerometers, one hydrophone in EPS1, and an additional hydrophone in GPK1. Station locations rely on a local UTM32‑based system centered on GPK1, with WGS84 coordinates derived from it. The exact GPK1 hydrophone position is missing.
