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.

Download or read book Pore-scale Modeling of the Impact of Surrounding Flow Behavior on Multiphase Flow Properties written by Robert Thomas Petersen and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate predictions of macroscopic multiphase flow properties, such as relative permeability and capillary pressure, are necessary for making key decisions in reservoir engineering. These properties are usually measured experimentally, but pore-scale network modeling has become an efficient alternative for understanding fundamental flow behavior and prediction of macroscopic properties. In many cases network modeling gives excellent agreement with experiment by using models physically representative of real media. Void space within a rock sample can be extracted from high resolution images and converted to a topologically equivalent network of pores and throats. Multiphase fluid transport is then modeled by imposing mass conservation at each pore and implementing the Young-Laplace equation in pore throats; the resulting pressure field and phase distributions are used to extract macroscopic properties. Advancements continue to be made in making network modeling predictive, but one limitation is that artificial (e.g. constant pressure gradient) boundary conditions are usually assumed; they do not reflect the local saturations and pressure distributions that are affected by flow and transport in the surrounding media. In this work we demonstrate that flow behavior at the pore scale, and therefore macroscopic properties, is directly affected by the boundary conditions. Pore-scale drainage is modeled here by direct coupling to other pore-scale models so that the boundary conditions reflect flow behavior in the surrounding media. Saturation couples are used as the mathematical tool to ensure continuity of saturations between adjacent models. Network simulations obtained using the accurate, coupled boundary conditions are compared to traditional approach and the resulting macroscopic petrophysical properties are shown to be largely dependent upon the specified boundary conditions. The predictive ability of network simulations is improved using the novel network coupling scheme. Our results give important insight into upscaling as well as approaches for including pore-scale models directly into reservoir simulators.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pore scale simulation has recently become an important tool for understanding multiphase flow behavior in porous materials. It enables detailed mechanistic studies of upscaled flow parameters such as capillary-pressure saturation curves, residual saturation of each phase, and relative permeability. However, direct modeling of multiphase flow given the complex solid surfaces in a porous medium is a non-trivial problem. In this work, we develop a new quasi-static, variational level set formulation capable of handling trapped phases as well as wettability. We extend our previous work [1, 2] for simple geometries, and develop a new parallelized code enabling application of the method in larger geometries. We compare our model results against several experimental and semi-analytical datasets. The model is first applied to both homogeneous and heterogeneously wet rhomboidal pores, and compared against semi-analytical solutions derived by Mason and Morrow [3]. Subsequently, we focus on a quasi-2D micromodel study of fluid-fluid displacement for different wettabilities, which is quantified using the displacement efficiency and fractal dimension of the displacement patterns [4]. We then study classic experiments by Haines [5] and Leverett [6] for measuring the capillary pressure and relative permeability curves in sphere packs and sandpacks, respectively. We match trends in trapping in sandpacks during drainage/imbibition experiments by Pentland et al. [7], and also compare it against predictions by several other pore-scale models. Finally, we confirm the pore-scale hypothesis suggested by DiCarlo et al. [8] for explaining experimental observations of three-phase relative permeability of the intermediate-wet phase in sandpack experiments. For these three-phase experiments, we propose an approximation based on finding phases trapped between constant curvature surfaces, using two-phase simulations. We demonstrate the versatility of our methods by applying it to these disparate experimental datasets, and suggest future applications of our work

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 Modelling Multiphase Flow Through Micro-CT Images of the Pore Space written by Ali Qaseminejad Raeini and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a numerical method for modelling two-phase flow through porous media directly at the pore scale. The volume of fluid method is used to capture the interface motion. The volume of fluid equation and the incompressible Navier-Stokes equations are discretised by the finite volume method using a single fluid methodology, with a discontinuity in the phase properties. Capillary forces are calculated using a new semi-sharp formulation and filtered, to allow for simulations at low capillary numbers and avoid non-physical velocities. They are applied into the Navier-Stokes equations using a semi-implicit formulation, which allows larger time steps at low capillary numbers. The numerical method is verified on several test cases, demonstrating its efficiency, stability and accuracy in modelling multiphase flow through porous media with complex interface motion and irregular solid boundaries. We present two-phase flow simulations on simple pore geometries and study the mechanisms controlling two-phase flow at the pore scale. Particularly, we study the effect of geometry and flow rate on trapping and mobilization of the non-wetting-phase. We introduce a new concept to upscale the subpore-scale forces and find the relations between the flow and the pore-scale pressure drops. These information can be used as input to pore-network models. As an example, we applied this concept to predict the threshold capillary number to prevent trapping during imbibition. Furthermore, we present two-phase flow simulations on two micro-CT images of porous media and show the effect of capillary number on the flow pattern, the trapped non-wetting phase saturation and blob sizes. We present a rigorous approach to relate the pore-scale forces controlling the flow to the Darcy-scale parameters and use it to obtain relative permeability curves. Overall, this thesis provides a methodology for a detailed pore-scale analysis of multiphase flow, serving as a rigorous foundation for large-scale modelling and prediction.

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.

Download or read book Investigating Capillary Pressure and Interfacial Area for Multiphase Flow in Porous Media Using Pore-scale Imaging and Lattice-Boltzmann Modeling written by Mark L. Porter and published by . This book was released on 2009 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in imaging technology and numerical modeling have greatly enhanced pore-scale investigations of multiphase flow and transport in porous media. It is now feasible to obtain high resolution 3-dimensional pore-scale data, and numerical methods such as the lattice- Boltzmann (LB) technique have been developed specifically for simulating such phenomena. Traditional macro-scale multiphase flow models rely heavily on empirical relationships. For example, the interaction between fluids at their interfaces is accounted for indirectly through the empirical relative permeability relationship. Nevertheless, it has recently been hypothesized that the single most important variable missing from current macro-scale models is the measure of interfacial dynamics between fluids within the pores. Furthermore, the empirical capillary pressure-saturation relationship used in macro-scale multiphase flow simulators has been shown to be a function of interfacial area per volume. This study focuses on (1) the measurement and modeling of the capillary pressure-saturation relationship; and (2) the characterization of the fluid-fluid interfacial area per volume as a function of saturation. The study synthesizes experimental results derived from pore-scale computerized micro-tomographic (CMT) images with LB simulations. An image analysis algorithm for quantifying fluid-fluid interfacial area per volume from experimental CMT and simulation images was developed and verified. The experimental results were shown to be in good agreement with values reported in the literature. Furthermore, the capillary ressure-saturation curves were used to validate a recently proposed macro-scale interfacial area model. New LB simulations of drainage and imbibition for an air-water system were developed, in which the full geometry from the experimental system was used to define the lattice. This allowed for the direct comparison of experimental and simulated phase distributions within the pores. LB simulations showed excellent agreement with experimental results, considering no optimization or calibration to the data was required. Collectively, results show that there is a complex functional relationship between capillary pressure, saturation and interfacial area that provides insights into multiphase flow and transport processes that can not be obtained from the capillary pressure-saturation relationship alone.

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.
