Available in PDF, EPUB and Kindle. Book excerpt: The study of multiphase flow through porous media is undergoing intense development, mostly due to the recent introduction of new methods. After the profound changes induced by percolation in the eighties, attention is nowadays focused on the pore scale. The physical situation is complex and only recently have tools become available that allow significant progress to be made in the area. This volume on Multiphase Flow in Porous Media, which is also being published as a special issue of the journal Transport in Porous Media, contains contributions on the lattice-Boltzmann technique, the renormalization technique, and semi-phenomenological studies at the pore level. Attention is mostly focused on two- and three-phase flows. These techniques are of tremendous importance for the numerous applications of multiphase flows in oil fields, unsaturated soils, the chemical industry, and environmental sciences.
Download or read book Porous Media Fluid Transport and Pore Structure written by F Dullien and published by Elsevier. This book was released on 2012-12-02 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Porous Media: Fluid Transport and Pore Structure presents relevant data on the role of pore structure in terms of transport phenomena in pore spaces. The information is then applied to the interpretation of various experiments and results of model calculations. This book emphasizes the discussion of ""flow through porous media"" in terms of interactions among the three main factors. These factors are transport phenomena, interfacial effects, and pore structure. An introductory chapter opens the text and presents some of the basic concepts and terms that will be encountered all throughout. Chapters 2 to 4 focus on the important foundations of the physical phenomena as applied in the pore space of porous media. These foundations are capillarity, pore structure, and single phase flow and diffusion. Chapters 5 to 7 discuss more in detail the different applications of pore structure to various operations and processes. Some of the concepts covered in this part of the book include flow and/or diffusion through a porous medium, simultaneous flow of immiscible fluids and immiscible displacement, and miscible displacement and hydrodynamic dispersion. This book is a good reference to students, scientists, and engineers in the field of chemistry, physics, and biology.

Available in PDF, EPUB and Kindle. Book excerpt: A new pore network extraction scheme is presented that uses geometrical, topological, and mineralogical features of natural porous media to construct digital, faithful representations of the pore space. This newly-developed methodology allows users to construct disordered three-dimensional pore network systems that can be used to model physically-based displacement mechanisms at the pore scale in natural porous media. This work has three main components: (1) digital image analysis, (2) equivalent pore network extraction, and (3) pore network modeling of single- and two-phase flow processes. The pore network extraction approach reads as input high-resolution images of pore space in a given porous medium. It uses advanced image processing techniques to identify and quantify important features such as global heterogeneity and local anisotropy to construct representative digital replicates of the medium in three dimensions. To this end, an automated computational method is introduced to replace subjective manual image analyses thereby mitigating uncertainty. Modern computational algorithms are incorporated to optimize data management. This allows us to scale-up the implemented algorithms to construct large, core-scale pore networks. These are digital porous media with dimensions identical to those of the rock samples used in physical flow experiments. The extracted pore networks are subsequently used to model immiscible two-phase flow in different sandstone and carbonate rock samples and to predict relative permeabilities and residual saturation. To handle the numerical analysis with this level of computational complexity effectively, we employ: (1) customized data structures for optimal data management, (2) network analysis for optimal multidimensional graph analysis, (3) high-performance computing techniques for maximizing the cache efficiency, and (4) data analytics and Big Data analogies to address simulation bottlenecks by strategically collecting, sorting, and mapping information.

Download or read book Pore Space Deformation and Its Implications for Multiphase Flow Through Porous Media Under Various Wettability Conditions written by Rui Wang and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pore space deformation significantly affects multiphase flow behavior in porous media. It alters the distribution of fluids at the pore scale which in turn leads to changes in the effective permeability, relative permeability, capillary pressure, etc. However, due to the lack of fundamental studies on the mechanisms correlating the pore-level fluid displacements with the pore space deformation, no compelling conclusions have been reached to account for the observed effects. To explore this correlation, a series of carefully characterized unsteady- and steady-state two-phase core-flooding experiments were performed on miniature sandpack samples under varying stress conditions while the pore space was being imaged using high-resolution x-ray microtomography techniques to acquire three-dimensional pore fluid configuration maps. In these studies, the deformation of the sandpack samples was characterized at both macro and micro scales. The impact of deformation on the frequency of various pore-scale fluid displacement mechanisms as well as fluid saturations and volumes during different flow processes (drainage and imbibition) were also investigated. Changes in the multiphase flow behavior, such as fluid velocity and pressure, were evaluated through direct simulations, which used a finite volume method to solve Navier-Stoke equations. Moreover, the variations in the in-situ capillary pressure caused by the pore space deformation were explored through interfacial curvature analysis. The relationship between relative permeabilities and effective stress was probed. Finally, in connection to the geological storage of carbon dioxide in deep saline aquifers, the impact of pore space deformation on residual trapping and dissolution of supercritical CO2 in brine saturated sandpacks was carefully examined through micro-scale flow experiments conducted under varying stress conditions. It was observed that in a water-wet porous medium, unsteady-state drainage can be both strengthened due to the higher fluid velocity and weakened by the increase in the threshold capillary pressure after the pore space contraction. By contrast, unsteady imbibition was affected solely by variations in the threshold capillary pressure and, consequently, was facilitated as the pore sizes reduced. During the steady-state core-flooding tests, additional drainage and imbibition displacements were triggered by the pore space expansion and contraction, respectively. Furthermore, it was found that wettability was one of the key properties that governed the impact of pore space deformation on the multiphase flow behavior in porous media. The wetting phase hydraulic conductivity was more sensitive to the pore space deformation than that of the non-wetting phase, because of their topologically different distributions in the pore space. Consequently, the relative permeability of the wetting phase decreased with the increase in the effective stress, while that of the non-wetting phase increased. However, this behavior changed as the wettability of the porous medium was altered to a weakly oil-wet state through a dynamic aging process. These studies provided novel insights into the fluid flow behavior in unconsolidated porous media under varying stress conditions, which are of ever-increasing importance to many subsurface applications, including hydrocarbon recovery, water management, CO2 sequestration, and hydrogen storage.
Download or read book Pore Scale Geochemical Processes written by Carl Steefel and published by Walter de Gruyter GmbH & Co KG. This book was released on 2015-09-25 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This RiMG (Reviews in Mineralogy & Geochemistry) volume includes contributions that review experimental, characterization, and modeling advances in our understanding of pore-scale geochemical processes. The volume had its origins in a special theme session at the 2015 Goldschmidt Conference in Prague. From a diversity of pore-scale topics that ranged from multi-scale characterization to modeling, this work summarizes the state-of-the-science in this subject. Topics include: modification of thermodynamics and kinetics in small pores. chemo-mechanical processes and how they affect porosity evolution in geological media. small angle neutron scattering (SANS) techniques. how isotopic gradients across fluid–mineral boundaries can develop and how these provide insight into pore-scale processes. Information on an important class of models referred to as "pore network" and much more. The material in this book is accessible for graduate students, researchers, and professionals in the earth, material, environmental, hydrological, and biological sciences. The pore scale is readily recognizable to geochemists, and yet in the past it has not received a great deal of attention as a distinct scale or environment that is associated with its own set of questions and challenges. Is the pore scale merely an environment in which smaller scale (molecular) processes aggregate, or are there emergent phenomena unique to this scale? Is it simply a finer-grained version of the "continuum" scale that is addressed in larger-scale models and interpretations? The scale is important because it accounts for the pore architecture within which such diverse processes as multi-mineral reaction networks, microbial community interaction, and transport play out, giving rise to new geochemical behavior that might not be understood or predicted by considering smaller or larger scales alone.

Download or read book Flow and Transformations in Porous Media written by Renaud Toussaint and published by Frontiers Media SA. This book was released on 2017-02-07 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid flow in transforming porous rocks, fracture networks, and granular media is a very active interdisciplinary research subject in Physics, Earth Sciences, and Engineering. Examples of natural and engineered processes include hydrocarbon recovery, carbon dioxide geo-sequestration, soil drying and wetting, pollution remediation, soil liquefaction, landslides, dynamics of wet or dry granular media, dynamics of faulting or friction, volcanic eruptions, gas venting in sediments, karst development and speleogenesis, ore deposit development, and radioactive waste disposal. Hydrodynamic flow instabilities and pore scale disorder typically result in complex flow patterning. In transforming media, additional mechanisms come into play: compaction, de-compaction, erosion, segregation, and fracturing lead to changes in permeability over time. Dissolution, precipitation, and chemical reactions between solutes and solids may gradually alter the composition and structure of the solid matrix, either creating or destroying permeable paths for fluid flow. A complex, dynamic feedback thus arises where, on the one hand, the fluid flow affects the characteristics of the porous medium, and on the other hand the changing medium influences the fluid flow. This Research Topic Ebook presents current research illustrating the depth and breadth of ongoing work in the field of flow and transformation in porous media through 15 papers by 72 authors from around the world. The body of work highlights the challenges posed by the vast range of length- and time-scales over which subsurface flow processes occur. Importantly, phenomena from each scale contribute to the larger-scale behavior. The flow of oil and gas in reservoirs, and the flow of groundwater on catchment scale is sensitively linked to pore scale processes and material heterogeneity down to the micrometer scale. The geological features of the same reservoirs and catchments evolved over millions of years, sometimes as a consequence of cracking and fracture growth occurring on the time scale of microseconds. The research presented by the authors of this Research Topic represents a step toward bridging the separation of scales as well as the separation of scientific disciplines so that a more unified picture of flow and transformation in porous media can start to emerge.

This book was released on 2011-05-09 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this standard reference of the field, theoretical and experimental approaches to flow, hydrodynamic dispersion, and miscible displacements in porous media and fractured rock are considered. Two different approaches are discussed and contrasted with each other. The first approach is based on the classical equations of flow and transport, called 'continuum models'. The second approach is based on modern methods of statistical physics of disordered media; that is, on 'discrete models', which have become increasingly popular over the past 15 years. The book is unique in its scope, since (1) there is currently no book that compares the two approaches, and covers all important aspects of porous media problems; and (2) includes discussion of fractured rocks, which so far has been treated as a separate subject. Portions of the book would be suitable for an advanced undergraduate course. The book will be ideal for graduate courses on the subject, and can be used by chemical, petroleum, civil, environmental engineers, and geologists, as well as physicists, applied physicist and allied scientists that deal with various porous media problems.
