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 2014-02-19 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermodynamically constrained averaging theory provides a consistent method for upscaling conservation and thermodynamic equations for application in the study of porous medium systems. The method provides dynamic equations for phases, interfaces, and common curves that are closely based on insights from the entropy inequality. All larger scale variables in the equations are explicitly defined in terms of their microscale precursors, facilitating the determination of important parameters and macroscale state equations based on microscale experimental and computational analysis. The method requires that all assumptions that lead to a particular equation form be explicitly indicated, a restriction which is useful in ascertaining the range of applicability of a model as well as potential sources of error and opportunities to improve the analysis.

This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

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

Download or read book Measurement and Pore scale Modeling of Capillary Pressure Hysteresis in Strongly Water wet Sandstones written by Behrooz Raeesi and published by . This book was released on 2012 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capillary pressure and contact angle hysteresis in porous media are important yet not fully understood phenomena. A fundamental problem in interpretation of the capillary properties of porous media is the effect of the interaction of wetting properties and pore geometry on interface curvature. Contact angles provide a fundamental measure of wetting. However, circumstances under which reproducible and unambiguous values of contact angle are observed are limited to special circumstances. Contact angles commonly exhibit hysteresis between advancing and receding conditions. The origin of the contact angle hysteresis may be related to either chemical or geometric phenomena or a combination of both. Small scale geometric features, such as surface roughness, can have a dominant effect on the effective contact angles at the three phase lines of contact boundaries that are essential to the existence of interfaces and determine their curvature. Hysteresis in drainage and imbibition observed for spreading conditions, when the contact angle is zero and there is no hysteresis in contact angle, is accentuated by the pore geometry and the non-uniform structure of the pore space. In the first part of this thesis, the effect of roughness on the effective contact angle is studied by applying the MS-P (Mayer, Stowe, Princen) method of computing interface curvatures, for the first time, to geometric models of surface roughness that include small scale periodic variation and retained fluid in grooves along the walls of tubes of constant cross section. The theoretical results are shown to be consistent with experimental results on the wetting behavior of combinations of roughened polymeric tubes and pure liquids that give a range of well-defined intrinsic contact angles (contact angles measured at smooth polymeric surfaces or deposited monolayers for pure liquids, usually against air). Most of the investigation reported in this thesis concerns hysteresis in porous media when the contact is zero for advancing and receding conditions. There have been numerous efforts to model hysteresis under this relatively simplified condition. Most of the published hysteresis data is for bead packs. There is a paucity of detailed experimental capillary pressure data for consolidated porous materials, such as porous sandstone and carbonate rocks. In this work, an improved porous plate method was developed to obtain accurate and relatively fast measurement of two-phase capillary pressure-saturation relationships including hysteresis cycles and scanning curves. Extensive sets of capillary pressure data and corresponding equilibration outflow diagrams for various rock and fluid systems including air-brine, mineral oil-brine and crude oil-brine in sandstones are presented and discussed. In order to understand the effects of the pore structure and displacement mechanisms on capillary hysteresis and trapping, a geologically realistic pore network model representing the pore structure of Berea sandstone was adapted and systematically modified to investigate effects of various pore network characteristics. These include pore size distribution, pore-to-pore and pore-to-throat correlations and coordination number, on the shape of capillary pressure curves and the magnitude of capillary pressure hysteresis and non-wetting phase trapping. Using the knowledge from the analysis, the network was then tuned to reproduce capillary pressure hysteresis experimental data for Bentheim sandstone. In order to simultaneously match the hysteresis trends and the residual NWP saturation, a snap-off criterion was introduced to the model based on the theoretical length/diameter ratio at which a cylindrical liquid bubble becomes unstable. The non-wetting phase residual saturation was matched by adjustment of the throat lengths and without further adjustments, the scanning hysteresis cycles at various initial saturations were closely predicted by the model. It is also shown that the predicted distribution of residual nonwetting phase is in close agreement with the reported experimental data for sandstone obtained by 3D micro-CT imaging and other methods of obtaining blob size distribution. The capabilities of the network model are extended to compute fluid-fluid and solid-fluid surface areas as a function of saturation. Comparison of work of displacement from the modeled capillary pressure data with changes in free surface energy from the model are used, for the first time, to calculate the efficiency of conversion of work to surface area and vice versa.
