Fracture-Liquid Transmissibility in Fractured Porous Media

SPE Reservoir Engineering, 1994
Summary The flow of oil phase in the gas/oil two-phase region in fractures is a key to production performance of fractured petroleum reservoirs where gravity drainage is the dominant mechanism. In this study, data on a set of experiments that center on flow of the oil phase in the fractures are presented.

Diffusion of a Contaminant in Fractured Porous Media

Health Physics, 1985
A theoretical model is developed for diffusion from a finite source of buried contaminant through a porous medium containing a fracture that reaches to the atmosphere. Important quantities are shown to be the burial depth, source width and fracture width, the soil porosity, the diffusion coefficients in the soil and the (air-filled) fracture, and the ...

Determination of the flow-wetted surface in fractured media

Journal of Contaminant Hydrology, 2000
ABSTRACTDiffusion and sorption in the rock matrix are important retardation mechanisms in radionuclide transport in fractured media. The surface area in contact with the flowing water so called flow-wetted surface controls the interaction with the rock matrix.

ON TWO-PHASE FLOW IN FRACTURED MEDIA

Mathematical Models and Methods in Applied Sciences, 2002
A model describing two-phase, incompressible, immiscible flow in fractured media is discussed. A fractured medium is regarded as a porous medium consisting of two superimposed continua, a continuous fracture system and a discontinuous system of medium-sized matrix blocks.

Fracturing in Dry and Saturated Porous Media

2017
It is now generally recognized that mode I fracturing in saturated geomaterials is a stepwise process. This is true both for mechanical loading and for pressure induced fracturing. Evidence comes from geophysics, from unconventional hydrocarbon extraction, and from experiments.

Attenuation Anisotropy in Fractured Media

Proceedings, 2014
In order to observe the effects of fractures on seismic response, a finite-difference wave equation method is developed to model wave propagation in anisotropic media, in which the elastic constants represent fractures effectively. As these elastic constants are frequency dependent, wave simulation is implemented in the frequency domain.

Flow in fractured porous media

Water Resources Research, 1977
The equations governing the flow of fluid through fractured porous media are derived. These equations consist of Darcy's law for fluid flow in the primary pores, equations of motion for fluid flow in the fractures, and two continuity equations. The system of equations is coupled by the interaction of fluid in the primary pores with fluid in the ...

Attenuation Anisotropy in Fractured Media

Proceedings, 2013
In order to observe the effects of fractures on seismic response, a finite-difference wave equation method is developed to model wave propagation in anisotropic media, in which the elastic constants represent fractures effectively.

Laser induced fractures in porous media

2020
Hydraulic fracturing is the most effective technique to enhance well productivity in the oil and gas industry. There are many logistical, operational and environmental concerns associated with existing techniques, including the potential risk of underground water contamination and earthquakes - the main reasons for the current debates regarding shale ...
