Book excerpt: A new attempt is made to study the mechanisms of particle invasions into porous media. The following subjects are described: A critical survey of the literature indicating that the mechanism of particle invasions is not known in sufficient detail. The pros and cons of existing particle measuring devices are briefly described. Results from a new laboratory study on particle characterizations are given. The results of the laboratory studies on the flow of particle suspensions through porous media (up to 200 md) are discussed. The effects of flow rate and particle concentrations on the amount of damage (i.e., permeability impairment) and depth of penetration (from core inlet towards outlet) are particularly emphasized. Filter methods (e.g., using millipore filter) cannot be used to determine particle invasions into porous medium. Any predictions of the injection problems based on millipore (or any other filter) measurements are useless and should be discarded.

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: Formation damage is the loss of inherent permeability of porous media and is of vital importance in petroleum engineering. One important mechanism of formation damage is particulate straining, where suspended solid particles jam the flow pathways and reduce its flow capability. Most studies of particulate transport have been performed in porous media of uniform pore size, such as sandstones and sandpacks. Carbonates often contain large openings, called vugs, which can affect the flow and transport properties (particle straining) of the porous medium. In this study, particle straining experiments are performed on multiple configurations of synthetic vuggy media. A novel method is introduced to generate synthetic vuggy glass bead cores: glass beads, with dissolvable inclusions, are sintered in the presence of air in a muffle furnace and later dissolved with a core flood. Smaller-sized glass beads are injected at multiple flow rate and injection concentrations and changes in porosity, permeability, vug size, and particle effluent volume are monitored using continuous pressure measurements and computed tomography scanning. The results are combined with quasi-2D streamline simulations to understand the particle deposition patterns in these vuggy media. Furthermore, spontaneous imbibition experiments are conducted on multiple configurations of these synthetic vuggy media and capillary rise is measured. Rudimentary vug-pore flow models are generated, and solved for spontaneous imbibition using a computational fluid dynamics solver, to better explain the behavior observed in the experiments. The results can be summarized as follows: (i) particles penetrate and deposit at a deeper depth when a vug is present; (ii) the particles deposit on the vug-matrix boundary and result in a smaller and smoother vug; (iii) the maximum change in the vug is observed at the bottom of the vug; and (iv) more particle deposition occurs in the matrix around the vug. The high permeability vugs cause flow convergence, which increases the particle-particle and particle-matrix interaction, and results in an increased number of particles dropping out of the flow stream. Each vug has a sphere of influence within which it will affect the particle flow pathway; if the sphere of influence of two vugs overlap, the particle will be affected by both the vugs, with the dominance depending on the separation between the particle and the vug. The results suggest that for the vug conditions studied, the vugs in series focus the flow and increase the depth of particle deposition and the total volume of particles deposited in the core. The vugs in parallel acts independently as separate vugs, with their separation greater than their individual sphere of influence, and do not dictate the deposition of injected particles. In future, this study can be carried forward by conducting experiments inside a CT machine, to enable time-lapse particle deposition maps, on proxy vuggy media or real rocks. Coupled with real-time porosity, permeability, and possibly resistivity measurements, new near-wellbore interpretative models can be envisioned for improved formation evaluation of vuggy carbonates

This book was released on 1993 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sophisticated models of the movement of particles, particularly bacteria and viruses, through porous media have been developed, but have met with limited success when compared to field observations some argue that the poor predictive capabilities of the models are due in part to the fact that most of the sophisticated models are tied to an assumptions of homogeneity within the flow field. In previous work, the structure of random percolation fields has been investigated and suggests application of percolation theory to heterogeneous porous media. One conclusion from this study as applied to particle transport is that as the distribution of pore throat sizes takes on variation in the third dimension, the probability of finding a continuous flow path with large throat size increases. One interpretation of this work, within the current context, leads to an argument that a saturated medium will become more open to transport of particles as the medium takes on three dimensional structure. The central hypothesis of the current project is therefore be stated: Particles which are suspended within the pore fluids of media demonstrating three-dimensional heterogeneities will be transported at higher average velocities and with less trapping than particles which are suspended in the pore fluids of media demonstrating one- or two-dimensional heterogeneities. This dependence on dimension is a function of the dimensional character of the heterogeneity, the length scales of the heterogeneity, the size of the particles, the hydrodynamics of the flow field, the degree of saturation of the medium, and the medium/particle interaction.

Available in PDF, EPUB and Kindle. Book excerpt: Particle-laden flows occur in a variety of natural and industrial situations. As particulate suspensions flow through a medium, particles are often retained at constrictions such as pore throats, outlets or orifices. This occurs not only with oversized particles, but also with particles smaller than the constriction. For instance, jams are caused by the formation of particle bridges/arches when several particles attempt to flow through a constriction simultaneously. In many instances the success of an operation depends on our ability to either ensure or stop the flow of particles in the flow stream. Managing the flow of sand into wellbores during hydrocarbon production from poorly consolidated sandstone reservoirs, also referred to as sand control, is one such application in the oil and gas industry. This dissertation presents a multi-pronged effort at modeling the flow of granular suspensions of different concentrations, and through pore openings of different shapes, with two main objectives: (1) predicting the mass and size-distribution of the particles that are produced before jamming, and (2) investigating the underlying factors that influence the onset and stability of particle arches. Since, the dominant interactions and retention mechanisms are concentration dependent, we divided particulate suspensions into three groups based on the volumetric particle concentration ([phi]). High-concentration suspension flows ([phi]>~50%) are dominated by particle-particle interactions. We modeled polydisperse sand packs flowing through screens with rectangular and woven-square openings using 3D discrete element method (DEM). Simulations were validated against experimental data for a wide range of screen opening and sand size distributions. From the experiments and DEM simulations, a new scaling relation is identified, in which the number of different sized particles produced before retention follows a power-law correlation with the particle-to-outlet size ratio. This correlation is explained with a simple probabilistic model of bridging in polydisperse systems and a particle-size dependent jamming probability calculated from experimental data. A new method is presented to estimate the mass and size distribution of the produced solids through screens. The method uses the entire particle size distribution (PSD) of the formation sand, is validated with experimental data and numerical simulations, and provides more quantitative and accurate predictions of screen performance compared to past methods. It is also found that the stability of particle arches is compromised when adjacent outlets are less than three particle diameters away from each other. Low-concentration suspension flows ([phi]

Book excerpt: This volume contains the lectures presented at the NATO ADVANCED STUDY INSTITUTE that took place at Newark, Delaware, U. S. A. , July 14-23, 1985. The objective of this meeting was to present and discuss selected topics associated with transport phenomena in porous media. By their very nature, porous media and phenomena of transport of extensive quantities that take place in them, are very complex. The solid matrix may be rigid, or deformable (elastically, or following some other constitutive relation), the void space may be occupied by one or more fluid phases. Each fluid phase may be composed of more than one component, with the various components capable of interacting among themselves and/or with the solid matrix. The transport process may be isothermal or non-isothermal, with or without phase changes. Porous medium domains in which extensive quantities, such as mass of a fluid phase, component of a fluid phase, or heat of the porous medium as a whole, are being transported occur in the practice in a variety of disciplines.

Available in PDF, EPUB and Kindle. Book excerpt: Granular Filtration of Aerosols and Hydrosols is concerned with the fundamental aspects of granular filtration of both liquid and gas suspensions. This book takes a unifying approach to the treatment of granular aerosol and hydrosol filtration. The text begins with the introduction of the process of granular filtration and its various applications. Subsequent chapters discuss the aspects of filtration, such as, the macroscopic description of fixed-bed granular filtration; the methods for making representations based on various porous media models for both clean and clogged filter media; the mechanisms of particle deposition; and the trajectory analysis of particle deposition. The final chapter presents and discusses case studies which deal with predicting and calculating the dynamic behavior of granular filtration of hydrosols and aerosols. Researchers in granular filtration and graduate students dealing with separation technology will find the book highly useful.

This book was released on 2020-08-19 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of fluid flow and heat transfer in a porous medium have been the subject of continuous interest for the past several decades because of the wide range of applications, such as geothermal systems, drying technologies, production of thermal isolators, control of pollutant spread in groundwater, insulation of buildings, solar power collectors, design of nuclear reactors, and compact heat exchangers, etc. There are several models for simulating porous media such as the Darcy model, Non-Darcy model, and non-equilibrium model. In porous media applications, such as the environmental impact of buried nuclear heat-generating waste, chemical reactors, thermal energy transport/storage systems, the cooling of electronic devices, etc., a temperature discrepancy between the solid matrix and the saturating fluid has been observed and recognized.
