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

Collection

The 1996 hydraulic programme at GPK‑2 included a production test, a major re‑stimulation injecting 28 000 m³ at rates up to 78 L/s, a stepped injectivity test, and two short circulation experiments between GPK‑2 and GPK‑1. Around 7 500 microseismic events were detected, with about 5 700 successfully located.

Flow logs - Soultz-sous-Forêts 1996 Stimulation and Hydraulic Tests

Dataset in collection Episode: 1996 Stimulation and Hydraulic Tests Soultz-sous-Forêts

Flow logs from GPK1 and GPK2 were recorded during the 1996 Soultz‑sous‑Forêts hydraulic programme, documenting depth‑dependent flow profiles (depth in m, flow in L/s) over multiple injection and circulation phases. Each file header contains the detailed acquisition parameters.

Hydraulic data - Soultz-sous-Forêts 1996 Stimulation and Hydraulic Tests

Dataset in collection Episode: 1996 Stimulation and Hydraulic Tests Soultz-sous-Forêts

Hydraulic data from GPK2, GPK1, and EPS1 were recorded during the 1996 Soultz‑sous‑Forêts hydraulic programme, covering production, stimulation, stepped‑injection, and two circulation tests. Five datasets document wellhead pressure, flowrate, temperature, and related hydraulic parameters, with full metadata provided in each file header.

Microseismic catalogue with moment magnitude of the downhole network from CSMA - Soultz-sous-Forêts 1996 Stimulation

Dataset in collection Episode: 1996 Stimulation and Hydraulic Tests Soultz-sous-Forêts

Microseismic catalogue of 3464 events recorded by the downhole network during the 1996 Soultz‑sous‑Forêts stimulation. The dataset covers only the stimulation phase and a few days after, with almost no events at low flow rates and a strong increase in seismicity during the 78 L/s injection stage.

Microseismic downhole network - Soultz-sous-Forêts 1996 Stimulation and Hydraulic Tests

Dataset in collection Episode: 1996 Stimulation and Hydraulic Tests Soultz-sous-Forêts

In 1996, three CSMA 4‑component accelerometers (in wells 4550, 4601, 4616) and one hydrophone (in EPS1) were deployed for the Soultz microseismic network. Sensors were not grouted.

Temperature logs - Soultz-sous-Forêts 1996 Stimulation and Hydraulic Tests

Dataset in collection Episode: 1996 Stimulation and Hydraulic Tests Soultz-sous-Forêts

Temperature logs from GPK1 and GPK2 were recorded during the 1996 Soultz‑sous‑Forêts hydraulic programme, documenting depth‑dependent temperature profiles (depth in meters, temperature in °C). Measurements were acquired on multiple dates in September–October 1996, with full acquisition details provided in each file header.

Catalogue with hydraulic data from Drif et al.(2024)- Soultz-sous-Forêts 1996 Stimulation

Dataset in collection Episode: 1996 Stimulation and Hydraulic Tests Soultz-sous-Forêts

Hourly hydraulic–seismic catalogue for the 1996 Soultz stimulation, starting 18/09/1996 12:00. It reports flowrate, injected volume, hydraulic energy, and the corresponding seismic response (event depth, cumulative moment, radiated and faulting energies) to evaluate how injected hydraulic energy converts into seismic energy, following Drif et al. (2024).
