Available in PDF, EPUB and Kindle. Book excerpt: Theory and Application of Multiphase Lattice Boltzmann Methods presents a comprehensive review of all popular multiphase Lattice Boltzmann Methods developed thus far and is aimed at researchers and practitioners within relevant Earth Science disciplines as well as Petroleum, Chemical, Mechanical and Geological Engineering. Clearly structured throughout, this book will be an invaluable reference on the current state of all popular multiphase Lattice Boltzmann Methods (LBMs). The advantages and disadvantages of each model are presented in an accessible manner to enable the reader to choose the model most suitable for the problems they are interested in. The book is targeted at graduate students and researchers who plan to investigate multiphase flows using LBMs. Throughout the text most of the popular multiphase LBMs are analyzed both theoretically and through numerical simulation. The authors present many of the mathematical derivations of the models in greater detail than is currently found in the existing literature. The approach to understanding and classifying the various models is principally based on simulation compared against analytical and observational results and discovery of undesirable terms in the derived macroscopic equations and sometimes their correction. A repository of FORTRAN codes for multiphase LBM models is also provided.

Download or read book Wettability in Porous Media From Macroscopic Measurements to Pore scale Characterization written by Prisca Andriamananjaona and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wettability refers to the relative affinity of a solid material for one fluid in the presence of another fluid. This property is usually inferred from the measurement of the contact angle formed at the triple-point, i.e. the point where the three phases meet. Wettability is a crucial parameter to be considered when dealing with multiphase flows in confined porous media as it dramatically impacts the fluids distribution. This property is therefore of major concern in the petroleum industry as it has, among others, an influence on the relative permeability, on the efficiency of one recovery process over another, and ultimately on the amount of recoverable oil. In an oil reservoir subjected to recovery by waterflooding for example, the amount of produced oil will highly differ if the rock is water wet, or oil wet. Despite the well-established correlation between wettability and recovery efficiency, its distinct characterization and impact at the pore-level remains poorly understood. Reservoir rocks are porous media, i.e. composed of a solid matrix and a connected pore-space. The fluids are located in micrometer-sized pores, rendering direct observation challenging. To overcome that difficulty, empirical measurements were devised to evaluate rocks wettability. The most widespread tests in the petrophysical community are based on the amount of recovered fluids after successive flows. The present work focuses on Amott tests performed on rock/water/oil systems. The wettability state is given by three indices obtained through recovery measurements after successive spontaneous and forced flow. The extreme wettability state presents no ambiguity whereas the intermediate states can be trickier to interpret. Different combinations of indices can yield the same global index, while referring to very different pore-scale phenomena. The advent of powerful imaging methods now allows observing the phenomena occurring in the pore-space. The objective of the current study aims at conciliating the classic macroscopic determination of the wettability state with its manifestation at the pore-scale. To do so, we use laboratory microcomputed tomography (μCT). This technique allows to access to the pore-scale in a non-destructive fashion. It is similar to the imaging methods used in medical applications, but with a resolution that allows to access to the micron scale. In this work, we therefore conduct μCT acquisitions after each flow step of the Amott test. However, as the Amott test is a volume-based measurement, it requires centimeter-sized sample to limit he measurement uncertainty, whereas the μCT technique requires millimeter-sized samples to be able to reliably vizualize the pore-space. To resolve this conflict, we perform our experiments on Bentheimer sandstone as the biggest portion of its pore space is observable by means of μCT, while still being a representative rock for conventional oil reservoirs. Furthermore, we choose to perform the Amott tests on at least two differents sample sizes: the classical plug (centimeter sized), and one or two mini-plugs, suitable for imaging. To be as representative as possible, all samples are subjected to the same flow conditions, at the same time. The first part of this work therefore focuses on the adaptation of the conventional experimental procedure towards small rock samples, and the validation of the change-of-scales: we especially highlight some end effects after spontaneous flow that impact the saturation state differently, depending on the sample size. The second part of the work focuses on the comparison between the wettability state given by the Amott test, and the corresponding analyses at the pore-scale. We confront three distinct wettability states covering the range from water-wet, over intermediate wet to oil wet. The pore-scale analyses corroborate the Amott test results, and help to advance the understanding of pore-scale phenomena.
Download or read book Wettability written by Erle C. Donaldson and published by Elsevier. This book was released on 2013-11-25 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: The wettability of oil reservoirs is the most important factor controlling the rate of oil recovery, providing a profound effect on petroleum production. The petroleum industry has increased the research effort on wettability, but, so far, there has been limited coverage on the topic. Wettability reviews the major research and applications on wettability, capillary pressure and improved recovery. Critical topics including core preservation, the effect of wettability on relative permeability, surface forces such as van der Waals equation of state, petroleum traps and pore size effects are all included in this musthave handbook. Deciphering the techniques and examples will increase the efficiency and production of oil recovery, translating to stronger reservoir simulations and improved well production.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims at presenting, describing, and summarizing the latest advances in polymer flooding regarding the chemical synthesis of the EOR agents and the numerical simulation of compositional models in porous media, including a description of the possible applications of nanotechnology acting as a booster of traditional chemical EOR processes. A large part of the world economy depends nowadays on non-renewable energy sources, most of them of fossil origin. Though the search for and the development of newer, greener, and more sustainable sources have been going on for the last decades, humanity is still fossil-fuel dependent. Primary and secondary oil recovery techniques merely produce up to a half of the Original Oil In Place. Enhanced Oil Recovery (EOR) processes are aimed at further increasing this value. Among these, chemical EOR techniques (including polymer flooding) present a great potential in low- and medium-viscosity oilfields. • Describes recent advances in chemical enhanced oil recovery. • Contains detailed description of polymer flooding and nanotechnology as promising boosting tools for EOR. • Includes both experimental and theoretical studies.
