Stress- and fluid-driven failure during fracture array growth: Implications for coupled deformation and fluid flow in the crust

Barnhoorn, Auke; Cox, Stephen; Robinson, David; Senden, Timothy

Description

Brittle experimental deformation on dolomite rocks shows for the first time the difference in growth of fracture networks by ordinary percolation and invasion percolation processes. Stress-driven fracture growth, in the absence of fluid pressure, is an ordinary percolation process characterized by distributed nucleation and growth of microfractures, which coalesce with increasing strain to form a connected fracture network. Fluid pressure-driven fracture growth is more akin to an invasion...[Show more]
