This book was released on 2013-06-29 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of many years of intensive study, our current abilities to quantify and predict contaminant migration in natural geological formations remain severely limited. The heterogeneity of these formations over a wide range of scales necessitates consideration of sophisticated transport theories. The evolution of such theories has escalated to the point that a review of the subject seems timely. While conceptual and mathematical developments were crucial to the introduction of these new approaches, there are now too many publications that contain theoretical abstractions without regard to real systems, or incremental improvements to existing theories which are known not to be applicable. This volume brings together articles representing a broad spectrum of state-of-the-art approaches for characterization and quantification of contaminant dispersion in heterogeneous porous media. Audience: The contributions are intended to be as accessible as possible to a wide readership of academics and professionals with diverse backgrounds such as earth sciences, subsurface hydrology, petroleum engineering, and soil physics.

This book was released on 1995 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research project is to investigate dispersion as a method of quantifying geological characterization and defining reservoir heterogeneity in order to enhance crude oil recovery. The dispersion of flow of a reservoir rock (dispersion coefficient and dispersivity) was identified as one of the physical properties of a reservoir rock by measuring the mixing of two miscible fluids, one displacing the other in a porous medium. A rock was 100% saturated with a resident fluid and displaced by a miscible fluid of equal viscosity and equal density. Some specific experiments were performed with unequal densities. Produced fluid was analyzed by refractometer, nuclear reaction, electrical conductivity and X-ray scan. Several physical and flow characteristics were measured on the sand rock sample in order to establish correlations with the measured dispersion property. Absolute permeability, effective porosity, relative permeability, capillary pressure, the heterogeneity factor and electrical conductivity were used to better understand the flow system. Linear, transverse, 2-D and 3-D dispersions were measured and used to characterize the rock heterogeneity of the flow system. A new system of measuring dispersion was developed using a gas displacing gas system in a porous medium. An attempt was also made to determine the dispersion property of an actual reservoir from present day well log data on a producing well. 275 refs., 102 figs., 17 tabs.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study developed a new method using dispersion measurements by which the flow characterization in a porous medium or reservoir can be determined. The fundamentals of the dispersion characteristic in consolidated porous media were investigated and employed to evaluate the reservoir characterization. A series of miscible displacement tests were conducted on Berea and Brown sandstones with different permeabilities, system lengths, and heterogeneity. The analytical methodologies, (1) X-ray computed tomograph (CT) method, (2) X-ray linear core scanning method, and (3) refractive index method, were utilized for dispersion measurements. The laboratory techniques developed in this study and the detailed experimental procedures are presented. The experimental results were analyzed by utilizing the concentration profiles obtained from experimental dispersion tests. The results have shown that the concentration profile appears to be a strong function of rock permeability and heterogeneity and that the dispersivity is a length dependent variable. The results show there exists a critical length in a dispersion measurement. A new parameter is defined and referred to as the dispersion factor. Both the laboratory dispersion factors and the field dispersion factors have been determined and discussed. The study concludes the dispersion factor can be used to evaluate the flow characterization of a miscible displacement, and that a dispersion factor measured in a field test is more representative of a given reservoir than dispersion factors measured in the laboratory. A large dispersion factor corresponds to miscible fluids flowing through a heterogeneous rock or reservoir, and a small dispersion factor corresponds to miscible fluids flowing through a homogeneous rock or reservoir.

Download or read book Percolation Theory for Flow in Porous Media written by Allen Hunt and published by Springer. This book was released on 2014-02-04 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents, for the first time, a unified and comprehensive introduction to some of the basic transport properties of porous media, such as electrical and hydraulic conductivity, air permeability and diffusion. The approach is based on critical path analysis and the scaling of transport properties, which are individually described as functions of saturation. At the same time, the book supplies a tutorial on percolation theory for hydrologists, providing them with the tools for solving actual problems. In turn, a separate chapter serves to introduce physicists to some of the language and complications of groundwater hydrology necessary for successful modeling. The end-of-chapter problems often indicate open questions, which young researchers entering the field can readily start working on. This significantly revised and expanded third edition includes in particular two new chapters: one on advanced fractal-based models, and one devoted to the discussion of various open issues such as the role of diffusion vs. advection, preferential flow vs. critical path, universal vs. non-universal exponents for conduction, and last but not least, the overall influence of the experimental apparatus in data collection and theory validation. "The book is suitable for advanced graduate courses, with selected problems and questions appearing at the end of each chapter. [...] I think the book is an important work that will guide soil scientists, hydrologists, and physicists to gain a better qualitative and quantitative understanding of multitransport properties of soils." (Marcel G. Schaap, Soil Science Society of America Journal, May-June, 2006)
