Abstract Hydro-mechanically induced transient changes in fracture volume elude an analysis of pressure and flow rate transients by conventional diffusion-based models. We used a previously developed fully coupled, inherently non-linear numerical simulation model to demonstrate that harmonic hydraulic excitation fractures leads systematic overtones the response spectrum can thus be as diagnostic...

The hydraulic behavior of fractured rocks under shear-thinning flow is a challenging topic interest in several fields, related either to environmental remediation or natural resources recovery. compound effect fluid rheology and medium heterogeneity strongly affects transport geological formations. Here, stochastic analysis conducted via Monte Carlo simulations investigate the fluids fractures ...

We investigate the influence of fluid rheology on flow in a finite rock fracture with vertically varying aperture and subject to competing drainage mechanisms due permeable substrate draining edge. The is release volume fluid, either Newtonian, Ostwald–deWaele, or Herschel–Bulkley. Hele–Shaw analogy between lubrication seepage flows allows extending our results porous medium permeability porosi...

In low-permeability gas reservoirs, horizontal wells have been used to increase the reservoir contact area, and hydraulic fracturing has been further extending the contact between wellbores and reservoirs. This paper presents an approach to evaluate horizontal well performance for fractured or unfractured gas wells, and a sensitivity study of gas well performance in low permeability formation. ...
