Book Description
The subject of this book is to study the porous media and the transport processes occur there. As a first step, the authors discuss several techniques for artificial representation of porous. Afterwards, they describe the single and multi phase flows in simplistic and complex porous structures in terms of macroscopic and microscopic equations as well as of their analytical and numerical solutions. Furthermore, macroscopic quantities such as permeability are introduced and reviewed. The book also discusses with mass transport processes in the porous media which are further strengthen by experimental validation and specific technological applications. This book makes use of state-of-the-art techniques for the modeling of transport processes in porous structures, and considers of realistic sorption mechanisms. It the applies advanced mathematical techniques for upscaling of the major quantities, and presents the experimental investigation and application, namely, experimental methods for the measurement of relevant transport properties. The main benefit of the book is that it discusses all the topics related to transport in porous media (including state-of-the-art applications) and presents some of the most important theoretical, numerical and experimental developments in porous media domain, providing a self-contained major reference that is appealing to both the scientists and the engineers. At the same time, these topics encounter a variety of scientific and engineering disciplines, such as chemical, civil, agricultural, mechanical engineering. The book is divided in several chapters that intend to be a resume of the current state of knowledge for benefit of related professionals and scientists.

Book Description
A porous material is a solid that is saturated by an interconnected network of pores filled with liquid or gas. It is an inorganic or organic cross linked or uncross linked containing pores of all sizes. The pore network is assumed to be continuous, forming two interpenetrating continua such as in a sponge. Examples of porous media range from porous silicon which is porous on the sub manometer scale to limestone caves and underground river systems on the kilometre scale. Most research on porous media analyses the transport processes in a macro scale approximation. This book focuses on semi-analytical solutions for thermo-poroelasticity field equations; pore size from units to hundreds of micro meters and assumptions and reactive processes as well as the mathematical formulations of these models. It represents the different concepts of porous media as it is used in many areas of applied science and engineering. This book presents current activities and new advances of porous media throughout the world.

Book Description
This book presents a new suite of benchmarks for and examples of porous media mechanics collected over the last two years. It continues the assembly of benchmarks and examples for porous media mechanics published in 2014. The book covers various applications in the geosciences, geotechnics, geothermal energy, and geological waste deposition. The analysis of thermo-hydro-mechanical-chemical (THMC) processes is essential to many applications in environmental engineering, such as geological waste deposition, geothermal energy utilisation, carbon capture and storage, water resources management, hydrology, and even climate change. In order to assess the feasibility and safety of geotechnical applications, process-based modelling is the only tool that can effectively quantify future scenarios, a fact which also creates a huge burden of responsibility concerning the reliability of computational tools. The book shows that benchmarking offers a suitable methodology for verifying the quality of modelling tools based on best practices, and together with code comparison fosters community efforts. It also provides a brief introduction to the DECOVALEX, SeSBench and MOMAS initiatives. This benchmark book is part of the OpenGeoSys initiative – an open source project designed to share knowledge and experience in environmental analysis and scientific computation.

Book Description
Volume 34 of Reviews in Mineralogy focuses on methods to describe the extent and consequences of reactive flow and transport in natural subsurface systems. Since the field of reactive transport within the Earth Sciences is a highly multidisciplinary area of research, including geochemistry, geology, physics, chemistry, hydrology, and engineering, this book is an attempt to some extent bridge the gap between these different disciplines. This volume contains the contributions presented at a short course held in Golden, Colorado, October 25-27, 1996 in conjunction with the Mineralogical Society of America's (MSA) Annual Meeting with the Geological Society of America in Denver, Colorado.

Book Description
Hereby I present a PhD thesis by publications. The thesis includes five journal papers, of which two have already been published and three have been submitted for publication and are presently under review. The journals include high-impact-factor ones (Water Resources Research, Applied Mathematics Letters and Transport in Porous Media), and also Journal of Petroleum Science and Engineering, which is a major academic journal in petroleum industry. The thesis develops a new version of so-called splitting theory. The current 2006-version of the theory encompasses analytical modelling of thermodynamically-equilibrium conservation law systems for two-phase multicomponent flow in porous media. The theory allows the derivation of numerous analytical solutions. The thesis generalizes the splitting method and applies it for flow systems with dissipation, non-equilibrium phase transitions and chemical reactions. It is shown how the general nxn system is split into an (n-1)x(n-1) auxiliary system and one scalar lifting equation. The auxiliary system contains thermodynamic parameters only, while the lifting equation contains transport properties and solves for phase saturation. First application of the splitting method is developed for low-salinity water-flooding. Two major effects are accounted for: the wettability alternation and the induction of fines migration, straining and attachment. One-dimensional (1D) problems of sequential injection of high-salinity water slug, low salinity water slug and high-salinity water chase drive corresponds to one of the most promising modern processes of Enhanced Oil Recovery, which currently is under intensive investigation in major world oil companies. Both auxiliary and lifting problems allow for exact solutions. The exact analytical solution consists of implicit formulae for profiles of phase saturations, salinity and fine particle concentrations. The exact solution allows for deriving explicit formulae in oil recovery. The solution permits the comparative study of the impact of both effects, which are the wettability alternation and the induction of fines migration, on incremental recovery. It was found out that both effects are significant for typical values of the physics constants. The exact solution allows for multi-variant study to optimize the injected water composition in a concrete oilfield. The second application of the splitting method corresponds to 1D displacement of oil by a low-salinity polymer slug followed by a low-salinity water slug and, finally, high salinity water chase drive. This problem corresponds to the Enhanced Oil Recovery Method that merges two traditional methods of polymer- and low-salinity water-floods. The exact analytical solutions are the result of the splitting system. The method was also generalized for the case of several low-salinity slugs and Non- Newtonian properties of the polymer solution. The exact solution yields explicit formulae for propagation of saturation and concentration shocks, dynamics of different flow zones and explicit formulae for incremental oil recovery. The analytical model developed allows optimizing polymer concentration and its slug size, salinity concentration and sizes of slugs for secondary and tertiary oil recovery. The third application of the new splitting method is oil displacement by suspensions and colloids of solid micro particles. The injection of one suspension or colloid with multiple particle capture mechanisms is assumed. The novelty of this work is considering numerous particle capture mechanisms and kinetic equations for the capture rates, which do not have a conservation law type. However, the system is susceptible for splitting by the introduction of Lagrangian co-ordinate and using it instead of time as an independent variable in the general system of Partial Differential Equations (PDEs). Introduction of the concentration potential linked with retention concentrations yields an exact solution for auxiliary problem. The exact formulae allow predicting the profiles and breakthrough histories for the suspended and retained concentrations and phase saturations. It also allows the calculation of penetration depth. The analytical models derived in the thesis are applicable also in numerous environmental and chemical engineering processes, including the disposal of industrial wastes in aquifers with propagation of contaminants and pollutants, industrial water treatment, injection of hot- or low-salinity water into aquifers and water injection into geothermal reservoirs.

Book Description
This volume contains the invited lectures presented during the NATO/ASI conducted in Pullman, Washington, July 9-18, 1989. This is the third in a series of NATO/ASIs on transport phenomena in porous media. The first two, which took place at Newark, Delaware in 1982 and 1985, are devoted to various topics related to the Fundamentals of Transport Processes in Porous Media. The contents of the books resulting from previous NATO/ASIs are given at the end of this book. Transport of extensive quantities such as mass of a fluid phase, mass of chemical species carried by a fluid phase, energy and electric charge in porous media, as encountered in a large variety of engineering disciplines, is an emerging interdisciplinary field. The groundwater flow, the simultaneous flow of gas, oil and water in petroleum reservoirs, the movement and accumulation of pollutants in the saturated and unsaturated subsurface zones, thermal energy storage in reservoirs, land subsidence in response to charges in overburden loads, or to pumping of fluids from underground formations, wave propagation in seismic investigations or as produced by earthquakes, chemical reactors, water flow through sand filters and the movement of fluids through kidneys, may serve as examples of fields in which the theory of transport in porous media is employed.
