1/16/2007 · [27] In the fractured shale terrain in Oak Ridge, Tennessee, more than 90% of the groundwater flow occurs in the lower part of the deeply weathered horizon, discharging into local streams without ever entering the fractured bedrock [Solomon et al., 1992]. Apparently, an efficient weathered zone short circuits the flow near the surface and

Dissertation On Flow In Fractured Rock

Description of multiphase flow in fractured porous media is a problem that cross cuts the earth sciences. Fractured media are found in the petroleum industry, geothermal industry, environmental sciences, and waste disposal sites. In some fractured reservoirs produced water is reinjected to maintain reservoir pressure and/or avoid environmental

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): This dissertation summarizes an experimental investigation of flow and transport of non-aqueous phase liquids (NAPLs) in fractured porous media, either in their own phase or as dissolved contaminants. We observed displacement mechanisms at the pore scale when two and three phases are present, using a …

Multiphase Flow in Highly Fractured Shale Gas Reservoirs

fracture-matrix flow including the effects of injection flow rate, fluid type, fracture orientation and flow direction. In the first section of this study (see Chapter 2), we analyze the impact of two different injection rates on the capillary dominated displacement of oil by water in fractured rock samples, using x-ray computed tomography.

The objectives of this study were: To review and understand flow and transport processes in unsaturated zones. In this study, particular emphasis is placed on understanding mechanisms that cause non-uniform (preferential) flow for two casestudies, namely the Cape Flats sandy environment and the Mpumalanga Highveld fractured rock environment. To evaluate the adequacy of models, in particular

In fractured rock systems, ground water flow is not as simple and as methodical as in a porous medium. To create a numerical model of such a flow system, a four-part algorithm was written, which included MATLAB$\sp\circler$ as a fundamental component. It was intended that the model output define the zone of influence of pumping stresses. The four model parts are, sequentially: generation of

Various theoretical approaches are used to model groundwater flow in fractured rock. This paper presents the application of several approaches to the restoration of the drainage of Rofla tunnel, Grisons, Switzerland.

One is flow equation; the other is reactive transport equation. The first equation is used to describe the total flow of contaminant wastes, which is based on Darcy law. The second one will characterize the adsorption, diffusion and convection behavior of contaminant species, which describes most features of contaminant flow we are interested in.
