Book Synopsis Multiphase Flow in Porous Media by : P.M. Adler
Download or read book Multiphase Flow in Porous Media written by P.M. Adler and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 196 pages. 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.
Book Synopsis Pore Space Deformation and Its Implications for Multiphase Flow Through Porous Media Under Various Wettability Conditions by : Rui Wang
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 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.

Book Synopsis Flow and Transformations in Porous Media by : Renaud Toussaint
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.

Book Synopsis Reservoir Compartmentalization by : S. J. Jolley
Download or read book Reservoir Compartmentalization written by S. J. Jolley and published by Geological Society of London. This book was released on 2010 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Reservoir compartmentalization - the segregation of a petroleum accumulation into a number of individual fluid/pressure compartments - controls the volume of moveable oil or gas that might be connected to any given well drilled in a field, and consequently impacts 'booking' of reserves and operational profitability. This is a general feature of modern exploration and production portfolios, and has driven major developments in geoscience, engineering and related technology. Given that compartmentalization is a consequence of many factors, an integrated subsurface approach is required to better understand and predict compartmentalization behaviour, and to minimize the risk of it occurring unexpectedly. This volume reviews our current understanding and ability to model compartmentalization. It highlights the necessity for effective specialist discipline integration, and the value of learning from operational experience in: detection and monitoring of compartmentalization; stratigraphic and mixed-mode compartmentalization; and fault-dominated compartmentalization"--Page 4 of cover.

Download or read book Multiphase Flow in Porous Media: the Impact of Capillarity and Wettability from Field-scale to Pore-scale written by Benzhong Zhao and published by . This book was released on 2017 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphase flow in the context of this Thesis refers to the simultaneous flow of immiscible fluids. It differs significantly from single-phase flow due to the existence of fluid-fluid interfaces, which are subject to capillary forces. Multiphase flow in porous media is important in many natural and industrial processes, including geologic carbon dioxide (CO2) sequestration, enhanced oil recovery, and water infiltration into soil. Despite its importance, much of our current description of multiphase flow in porous media is based on semi-empirical extensions of single-phase flow theories, which miss key physical mechanisms that are unique to multiphase systems. One challenging aspect of solving this problem is visualization-flow typically occurs inside opaque media and hence eludes direct observation. Another challenging aspect of multiphase flow in porous media is that it encompasses a wide spectrum of length scales-while capillary force is active at the pore-scale (on the order of microns), it can have a significant impact at the field-scale (on the order of kilometers). In this Thesis, we employ novel laboratory experiments and mathematical modeling to study multiphase flow in porous media across scales. The field-scale portion of this Thesis focuses on gravity-driven flows in the subsurface, with an emphasis on application to geological CO2 storage. We find that capillary forces can slow and stop the migration of a CO2 plume. The meso-scale portion of this Thesis demonstrates the powerful control of wettability on multiphase flow in porous media, which is manifested in the markedly different invasion protocols that emerge when one fluid displaces another in a patterned microfluidic cell. The pore-scale portion of this Thesis focuses on the impact of wettability on fluid-fluid displacement inside a capillary tube. We show that the contact line movement is strongly affected by wettability, even in regimes where viscous forces dominate capillary forces.
Book Synopsis Multiscale Transport in Porous Media and Patterned Surfaces by : Bowen Ling
Download or read book Multiscale Transport in Porous Media and Patterned Surfaces written by Bowen Ling and published by . This book was released on 2016 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this dissertation is to establish a framework to describe multi-scale transport through porous media. Transport of mass and momentum in porous media can be studied at two different scales: the macro-scale (averaged-, continuum- or Darcy-scale) and the micro-scale (pore-scale). Particularly challenging from the modeling perspective are coupled systems (e.g. channel-matrix systems) and/or inherently unstable phenomena (e.g. multiphase transport). The former require multiscale approaches since the quantities of interest on one scale (e.g. macro-scale) may depend on the properties or physics at another scale (e.g. micro-scale). The latter challenge the very basic concept of system reproducibility as well as the perturbative approaches on which upscaling methods are generally based upon. The first part of this dissertation focuses on multi-scale mass transport in a two-dimensional channel embedded between two porous surfaces. By means of perturbation theory and asymptotic analysis, we first derive the set of upscaled equations describing mass transport in the coupled channel-matrix system and an analytical expression relating the macro-scale dispersion coefficient with the surface properties, namely porosity and permeability. Our analysis shows that their impact on dispersion coefficient strongly depends on the magnitude of Peclet number, i.e., on the interplay between diffusive and advective mass transport. Our analysis shows the possibility of controlling the dispersion coefficient, i.e. transversal mixing, by either active (i.e. changing the operating conditions) or passive mechanisms (i.e. controlling matrix effective properties) for a given Peclet number. Then, we compare the upscaled model against experiments conducted on microchannels with surfaces patterned with different topologies. The experimental data are in agreement with the developed theory and quantitatively confirm the impact of the matrix geometry on tranverse dispersion at different Peclet numbers. The second part of this dissertation focuses on experimentally quantifying and improving the reproducibility of pore-scale multiphase flow experiments. The unstable nature of multiphase flows in porous media questions the basic concepts of both reproducibility and experimental benchmarking for numerical codes' validation and calibration. Subpore-scale heterogeneity and temporal fluctuations of experimental equipment can strongly control two-phase flow displacement data. We experimentally demonstrate that the introduction of spatial heterogeneity in pore-scale microfluidic models improves the reproducibility of multiphase flow experiments, and variability in fluid displacement between different realizations of the same experimental pore structure can be numerically captured by stochastic numerical simulations. The latter appears to be a more appropriate framework to describe unstable pore-scale displacement in multiphase transport.

Available in PDF, EPUB and Kindle. Book excerpt: Modeling three-phase flows through porous media is of great importance in the improved oil recovery processes. In order to predict the three-phase relative permeabilities and capillary pressure functions in regions of the reservoir where water, oil, and gas flow simultaneously, a proper understanding of the basic three-phase displacement mechanisms and multiphase flow physics is required. There are numerous models dealing with multiphase flow in porous media, but not many of them include all necessary fundamental phenomena and physics, which may lead a less reflective result.
