Description succincte (Anglais)	The development of safe stimulation protocols for EGS is a key issue with a strong societal and economic impact. To optimize stimulation and minimize seismic risk, the role of fluid injection in earthquake physics needs to be understood. However, the effect of acid fluid on fault mechanics is still not clear, with implications for matrix acidizing stimulation. Here we propose an experimental study aimed at investigating earthquake nucleation and propagation in the presence of acid fluids.
