GeoEnergy Lab EPFL

Our lab research focus on couplings between fluid flow & fracture and applications in environmental & geo- engineering, seismology and tectonophysics.

The SwissMech webinar series by the mechanics faculty at @ETH_en and @EPFL_en shows insights into their excellent research. Check out all presentations and recordings from the academic year 2021/2022 on our website: https://t.co/oCp3boFi8S

Among other results, we find that aseismic moment release (M) scales with injected volume (V) as M ~ V^(3/2). n/n

[Robert Viesca @ViescaRobert]

We derive analytical solutions for rupture propagation and slip profiles, and use these solutions to validate a more general numerical solution procedure. 4/n

[Robert Viesca @ViescaRobert]

For this 3D problem, fault slip spreads self-similarly, and the rupture front either outpaces (λ>>1) or lags (λ<<1) the fluid front. 3/n

[Robert Viesca @ViescaRobert]

We examine fluid injection and migration in a fault zone, where the fault respects Mohr-Coulomb friction. 2/n

The power‐law rheology should be simply abandoned in hydraulic fracture modeling in favor of models capturing both the small/large shear rates limits. Check out our last paper #nag https://t.co/are4HSryDp

Do hydraulic fractures stop immediately after the end of injection? No! Under some conditions, significant post-shut-in propagation might occur. Find out the details in our new paper https://t.co/G9sX9iq8x5
