This book was released on 2019-02-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capillary phenomena occur in both natural and human-made systems, from equilibria in the presence of solids (grains, walls, metal wires) to multiphase flows in heterogeneous and fractured porous media. This book, composed of two volumes, develops fluid mechanics approaches for two immiscible fluids (water/air or water/oil) in the presence of solids (tubes, joints, grains, porous media). Their hydrodynamics are typically dominated by capillarity and viscous dissipation. This first volume presents the basic concepts and investigates two-phase equilibria, before analyzing two-phase hydrodynamics in discrete and/or statistical systems (tubular pores, planar joints). It then studies flows in heterogeneous and stratified porous media, such as soils and rocks, based on Darcy’s law. This analysis includes unsaturated flow (Richards equation) and two-phase flow (Muskat equations). Overall, the two volumes contain basic physical concepts, theoretical analyses, field investigations and statistical and numerical approaches to capillary-driven equilibria and flows in heterogeneous systems

Available in PDF, EPUB and Kindle. Book excerpt: This book provides concise, up-to-date and easy-to-follow information on certain aspects of an ever important research area: multiphase flow in porous media. This flow type is of great significance in many petroleum and environmental engineering problems, such as in secondary and tertiary oil recovery, subsurface remediation and CO2 sequestration. This book contains a collection of selected papers (all refereed) from a number of well-known experts on multiphase flow. The papers describe both recent and state-of-the-art modeling and experimental techniques for study of multiphase flow phenomena in porous media. Specifically, the book analyses three advanced topics: upscaling, pore-scale modeling, and dynamic effects in multiphase flow in porous media. This will be an invaluable reference for the development of new theories and computer-based modeling techniques for solving realistic multiphase flow problems. Part of this book has already been published in a journal. Audience This book will be of interest to academics, researchers and consultants working in the area of flow in porous media.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving our understanding about the evolution of multiphase flow in porous media is crucial for many applications such as extraction of hydrocarbons and geothermal energy from subsurface reservoirs, ground-water remediation, CO2 capture and storage, and transport of contaminants in aquifers and soil. Although such applications have implications at very large length scales, e.g., in the orders of kilometers, they strongly depend on the complex physics and dynamics that mainly occur at the pore-scale. Studying multiphase flow at the pore-scale using direct numerical modeling requires developing accurate numerical frameworks that not only honor conservation laws of mass, momentum, and energy, but also can precisely represent and track fluid-fluid interfaces in space and time in the presence of complex embedded solid geometries. In this dissertation, we consider incompressible and immiscible two-phase flows under isothermal conditions and in electrokinetic equilibrium. We solve for the conservation of mass and momentum, and using an immersed boundary approach account for the presence of embedded solid boundaries. We use a two-phase flow modeling approach based on the level-set method to capture the interfacial dynamics of the flow. Using our numerical framework, we first validate recent experimental works on phase separation in the form of pinch-off at the pore-scale, then we extend such experimental observations to a wide range of wettability conditions. For the phase separation in the form of pinch-off, we provide a quantitative study of the emerging length and time scales and their dependence on the wettability conditions, capillary effects, and viscous forces. Afterward, we present a subgrid thin-film model in order to resolve the interfacial dynamics of thin-films on curved solid surfaces in porous media. We couple a Navier-Stokes solver with a topology-preserving level-set method and a sub-grid thin-film model in order to simulate immiscible two-phase pore-scale flows in the presence of thin-films on curved solid surfaces. We validate our proposed subgrid thin-film model for the cases of static and dynamic fluid-fluid interfaces in capillary tubes (both drainage and imbibition) in the presence of curved solid surfaces. We compare the thin-film profile obtained by the subgrid thin-film model versus the profile numerically resolved by refined computational grid cells spanning the subgrid resolution of the thin-film and achieve a great agreement. Subsequently, we consider granular porous media with homogeneous and heterogeneous wettability conditions. We investigate the influence of capillary and viscous forces as well as wettability conditions on the interfacial dynamics, displacement efficiency, phase trapping phenomenon, and interfacial instabilities. For the heterogeneous wettability conditions, we consider granular media with mixed-wet conditions as well as fractional (patterned) wettability conditions. Finally, at the end of this dissertation, we present a physics-constrained super-resolution framework that can super-resolve numerical simulation data in both space and time. We test the robustness of our proposed super-resolution framework for super-resolving simulation data obtained for a turbulent flow case of Rayleigh-Bénard convection problem as well as a case of two-phase flow interfacial dynamics in porous media for a subsurface reservoir.

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.

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.

This book was released on 2021 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliable, physics-based predictions of two-phase flow and solute transport properties (e.g., relative permeability and dispersion coefficient) of porous media and fractures are crucial for reducing the uncertainty in performance predictions of many subsurface applications such as carbon dioxide (CO2) sequestration, enhanced oil recovery, and remediation of contaminated groundwater. However, problems of multi-phase flow in disordered porous media are exceedingly difficult due to, for instance, complicated pore space geometries and topologies, wettability conditions, and fluid–fluid displacements. Furthermore, even though the majority of subsurface reservoirs have natural or induced fractures, there is still no consensus regarding two-phase fluid flow behaviors in rough-walled fractures because of the intricate aperture-field geometries and their impacts on fluid–fluid interactions. Therefore, the development of physics-based models that can accurately predict flow and transport properties of disordered porous media and rough-walled fractures is warranted. In this study, we developed two new heavily-parallelized, dynamic pore-scale modeling platforms that can better account for the underlying displacement and transport physics and thereby predict the corresponding macroscopic properties. Both modeling frameworks incorporate many advanced features that have not been collectively used in previous dynamic models. For instance, they rigorously solve for the capillary, viscous, and buoyancy forces, integrate detailed descriptions of pore-scale fluid displacement dynamics, and explicitly account for flow through wetting layers forming in corners and rough surfaces of pore spaces. These modeling platforms further benefit from heavy parallelization and advanced domain decomposition techniques to achieve computational efficiency. We utilize the dynamic models to carry out various two-phase displacement simulations in core-sized pore networks constructed from high-resolution x-ray images of sandstone rock samples and a Berea sandstone fracture. Measured two-phase relative permeability data and fluid occupancy maps for both primary drainage and imbibition displacements are employed to validate our network models and probe their predictive capabilities. Afterward, the validated models are utilized to investigate a series of critical two-phase flow and solute transport properties including fluid trapping behaviors in porous media and rough-walled fractures under a broad range of fluid properties and flow conditions, relative permeability curves of single fractures with different geometric features, and dispersive solute transport behaviors in a sandstone rock sample under both single- and two-phase fluid configurations. These findings are of fundamental importance to understanding the physics governing fluid flow and solute transport in subsurface systems as well as field-scale predictions of two-phase flow in porous media and fractures.
