A theory has been developed for calculating interlayer conductivity for natural porous systems, such as sedimentary rocks. As the materials investigated are mainly made up of silica and alumina minerals, an electrical double layer can be presumed, wh

Besides the knowledge of material constants of the homogeneous phases of a disperse system, a good understanding of its geometrical properties is necessary for describing physical processes. In order to characterize the shape of the interface between

SUMMARY Based on self organized growth, a self-similar geometrical model of rock materials is established. The structural mode of the internal surface is carried over to the three-dimensional structure of the pore space and solid phase, which can be

In a paper presented at last year's Amsterdam meeting (viz. Geophysical Prospecting 14 (1966), 3, 301–341), J. R. Schopper derived formulas relating formation factor, permeability and porosity, by means of a statistical-network approach and by trea

As shown previously by the author, the relations between formation factor, permeability, and porosity can be expressed in statistical parameters of the microscopic pore system. A number of other macroscopically measurable quantities depend on those s

In [50] and [51] a theory has been developed relating formation factor, permeability and porosity of porous sedimentary rock by means of statistical parameters of the pore system, and further, tying those statistical parameters to other macroscopical

The knowledge of hydraulic and electric properties of porous media and the relations between them is essential for the quantitative evaluation of electric well logs and the solution of other reservoir engineering problems. The state of the art in thi
