Fractal Analysis of Permeability of Unsaturated Fractured Rocks
A physical conceptual model for water retention in fractured rocks is derived while taking into account the effect of pore size distribution and tortuosity of capillaries. The formula of calculating relative hydraulic conductivity of fractured rock is given based on fractal theory. It is an issue to choose an appropriate capillary pressure-saturation curve in the research of unsaturated fractur...
متن کاملPermeability and Relative Permeability in Rocks
Important features of the topology of the pore space of rocks can be usefully quantiied by analyzing digitized images of rock cross sections. One approach computes statistical correlation functions using modern image processing techniques. These correlation functions contain information about porosity, speciic surface area, tortuosity, formation factor, and elastic constants, as well as the uid...

متن کاملModeling Fluid Flow and Electrical Resistivity in Fractured Geothermal Reservoir Rocks
Phase change of pore fluid (boiling/condensing) in rock cores under conditions representative of geothermal reservoirs results in alterations of the electrical resistivity of the samples. In fractured samples, phase change can result in resistivity changes that are more than an order of magnitude greater than those measured in intact samples. These results suggest that electrical resistivity mo...
متن کاملPorePy: An Open-Source Simulation Tool for Flow and Transport in Deformable Fractured Rocks
Fractures are ubiquitous in the subsurface and strongly affect flow and deformation. The physical shape of the fractures, they are long and thin objects, puts strong limitations on how the effect of this dynamics can be incorporated into standard reservoir simulation tools. This paper reports the development of an open-source software framework, termed PorePy, which is aimed at simulation of fl...
