..., fluid flux and PVT properties. Sanding is the outcome of fluid drags overcoming rock aggregates' frictional resistance. As part of numerical model validations, two sets of field observations in cased and perforated wells were examined that involve effects of changes in gas PVT properties with depletion...

... ABSTRACT: Following rock disaggregation, sanding in oil and gas wells is principally driven by the fluid flow induced drag forces overcoming frictional resistance of rock aggregates. The empirical Hill-Koch-Ladd (HKL) correlation of viscous drag force to the Reynolds number, fluid flux, fluid...

... more accurately predicts transient flow for incompressible fluids with modest Reynolds numbers through fractures with time and/or spatially varying aperture. The RDFF model is derived from the two-dimensional Navier-Stokes equations and yields a two-field model (fluid flux and pressure) governed...

... by simulations based on the cubic law. These include (1): fracture fluid flow induced by seismic waves, (2) phase shifts between pressure, aperture, and flux fields, (3) non-Darcian flow in the direction of positive pressure gradients, (4) negative near well bore fluid pressures induced by high velocity radial...

... simulated and observed wellbore pressures, fracture radiuses and entering fluxes over time. Second, on LB2 block, we studied the fracture behavior using two one-cluster stages (with different injection rates) with multiple perforation-like entries azimuthally distributed in a 60-degree phasing configuration...

.... In this contribution, based on the known shale permeability, on the known percentage of gas extraction from shale stratum, and on two key features of the measured gas outflow which are (1) the time to peak flux and (2) the halftime of flux decay, it is shown that the fracturing process is characterized by a very dense...

... and would result in a redistribution of the cross-repository moisture flux. Lateral flow would be directed down-dip of the site-scale stratigraphy. Therefore, cross-repository flux would be reduced at the up-dip ends of the thermal-mechanical altered zones and increased at the down-dip ends. Consequently...

... which has been successful in explaining the observed behavior of rocks. In this paper, a theory of permeability is developed which draws on the concepts employed in previous work. The permeability involves three factors, the average fluid flux per crack, the number of cracks per unit area...
