In situ observations on the coupling between hydraulic diffusivity and displacements during fault reactivation in shales

Guglielmi, Y. Elsworth, D. Cappa, F.

Key questions in fault reactivation in shales relate to the potential for enhanced fluid transport through previously low-permeability aseismic formations. Here we explore the behavior of a 20 m long N0-to-170°, 75-to-80°W fault in shales that is critically stressed under a strike-slip regime (σ1 = 4 ± 2 MPa, horizontal and N162° ± 15°E,...

Strain and Flow Pathways in a Shale Fault Zone: An In-Situ Test of Fault Seal Integrity

Henry, P Guglielmi, Y. Gout, C.

A series of small scale (decametric) injection tests were performed in a small fault at IRSN Tournemire underground laboratory in Toarcian shales. Pressure, induced strains and flow rate were monitored at the injection borehole. Monitoring systems comprising strain sensors and a resistivity streamer were installed in observation boreholes...
