Abstract

 A conceptual model is presented for non-Newtonian fluid flow in fractured media. The fluid is represented via a truncated power-law model, the fracture aperture via a stochastic model  The fracture flowrate is derived for flow perpendicular to aperture variation as a function of the parameters describing the fluid rheology and the variability of the aperture field  Adoption of the pure power law model leads to overestimation of the flowrate with respect to the truncated model, more so for large external pressure gradient and/or aperture variability
