Diffusion of a Contaminant in Fractured Porous Media
Health Physics, 1985A 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 ...

Permeability of fractured porous media
ECMOR VII - 7th European Conference on the Mathematics of Oil Recovery, 2000Flow in fractured porous media was first investigated by Barenblatt and Zheltov (1960) and Barenblatt et al. (1960) by means of the double porosity model. A direct and complete solution of the flow in such media is given in this paper. Some preliminary results are presented and discussed; they show the importance of the percolation threshold of the ...

Flow in fractured porous media
Water Resources Research, 1977The 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 ...

Laser induced fractures in porous media
2020Hydraulic 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 ...

Fracturing in Dry and Saturated Porous Media
2017It 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.

Fracture-Liquid Transmissibility in Fractured Porous Media
SPE Reservoir Engineering, 1994Summary 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.
