A FRACTAL NETWORK MODEL FOR FRACTURED POROUS MEDIA
Fractals, 2016The transport properties and mechanisms of fractured porous media are very important for oil and gas reservoir engineering, hydraulics, environmental science, chemical engineering, etc. In this paper, a fractal dual-porosity model is developed to estimate the equivalent hydraulic properties of fractured porous media, where a fractal tree-like network ...

Wave propagation in disordered fractured porous media
Physical Review E, 2014Extensive computer simulations have been carried out to study propagation of acoustic waves in a two-dimensional disordered fractured porous medium, as a prelude to studying elastic wave propagation in such media. The fracture network is represented by randomly distributed channels of finite width and length, the contrast in the properties of the ...

Modelling of hydro‐fracture flow in porous media
Engineering Computations, 2010PurposeThe mechanical response of the skeleton of a porous medium is highly dependent on its seepage behaviour as pore pressure modifications affect the in situ stress field. The purpose of this paper is to describe how u‐p formulation is employed using an explicit time integration scheme where fully saturated and single‐phase partially saturated ...

Multiphase-Flow Properties of Fractured Porous Media
Proceedings of SPE Western Regional Meeting, 1999Abstract The fluid transfer parameters between matrix and fracture are not well known. Consequently, simulation of fractured reservoirs uses, in general, very crude and unproved hypothesis such as zero capillary pressure in the fracture and/or relative permeability functions that are linear with saturation.

Numerical Methods for Flow in Fractured Porous Media
2011We present a numerical technique for the simulation of salinity- as well as thermohaline-driven flows in fractured porous media. In this technique, the fractures are represented by low-dimensional manifolds, on which a low-dimensional variant of the PDEs of variable-density flow is formulated.

Response testing of piezometers in fractured porous media
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1975Conventional methods of piezometer response testing are unsuitable for analyzing observed data from three piezometers placed in fractured coal and siltstone units. However, these responses correspond closely to the results of pressure tests in fractured limestones (Pollard).

Capillary Pressure in Fractured Porous Media
SPE California Regional Meeting, 1989ABSTRACT A phenomenological model for fracture capillary pressure has been proposed. In this model, the fracture faces are assumed to be covered with cones, where every cone contacts the tip of another opposing cone. Cones in contact at the tip represent both roughness and aperture of a fracture surface. The solution to the Laplace-Young

Macroscopic properties of fractured porous media
Physica A: Statistical Mechanics and its Applications, 2010Abstract The macroscopic properties of fractured porous media locally governed by a Laplace equation are determined by several methods. The first one consists in discretizing the porous medium and the fractures and in solving the Laplace equation in the discretized structure. The other methods consist in successive upscalings.
