Summary: This delivreable presents the results of a complete sensitivity analysis performed on the OVSP data in the geological context of Soultz-sous-Forêts geothermal site. It provides numerous synthetic seismic experiments helping the readers to understand the capabilities and the robustess of the applied method. As the result, the full wave inversion (FWI) method is able to provide the localisation of the modeled faults and characterize them accurately. The FWI and in the acceptable noisy level, detect, delineate and characterize with reliability and accuracy the faults (even thin faults compared to the wavelength). We also improved our understanding of the structural geology around the site, and the 3D structural model has been improved. Uncommon seismic features observed in the OVSP real data have been reproduced qualitatively and understood.
D3.8 – Fiber optic behaviour in very saline conditions (Confidential)
Summary: Distributed Fibre Optic Sensing is an innovative technology enabling to turn a fibre optic into hundreds to thousands of sensors. Using this solution, various parameters can be monitored such as temperature, strain or acoustic. The installation of fibre optic cables in wells then appears as a powerful solution for the monitoring of geothermal production impacts on the underground. In order to study the durability of such installation in harsh geothermal contexts, fibre optic integrity is monitored both with an experimental study and using the results of two deployments in the geothermal plant of Soultz-sous-Forêts. This work also involved the monitoring of temperature, strain and of possible induced seismicity, using the combination of Distributed Temperature Sensing (DTS), Distributed Strain and Temperature Sensing (DSTS) and Distributed Acoustic Sensing (DAS).
