Rock Fractures and Fluid Flow: Practical Problems
Fractures provide preferential flow paths that define the rock mass internal “plumbing”, especially in low matrix-permeability rocks. Therefore, the rock mass hydraulic response results from the fracture density, orientation, and the stress-sensitive fracture transmissivity (Barton et al. 1995 ; Zimmerman … See more Numerical results highlight profound differences in the evolution of geometric aperture and flow during normal loading and shear … See more We compiled a database of fracture transmissivity evolution with normal stress and shear displacement for various rock types. Data sources cover a wide range of measurement … See more Carbonate rocks exhibit high solubility and high reaction rates (Plummer et al. 1978). Consequently, mineral dissolution, and precipitation play a … See more Web26 Apr 2024 · Fractures are breaks or mechanical discontinuities in rock that consist of two rough surfaces in partial contact.
