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.

Book Synopsis Linking Pore-scale Fluid-Fluid Interfacial Curvature in Porous Media to Capillary Pressure and Local Morphology with A Novel Method for Curvature Measurement by : Tianyi Li
Download or read book Linking Pore-scale Fluid-Fluid Interfacial Curvature in Porous Media to Capillary Pressure and Local Morphology with A Novel Method for Curvature Measurement written by Tianyi Li and published by . This book was released on 2015 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems that contain multi-phase flow in porous media are of interest in diverse fields including environmental engineering, hydrogeology, and petroleum engineering etc. One of the main descriptors of multi-phase flow in porous media is the relationship between capillary pressure and fluid saturation. Capillary pressure is inherently a pore-scale variable and is generally measured externally by a pressure transducer. As an alternative, it has recently become possible to estimate capillary pressure from images by using curvature values using the Young-Laplace equation. X-ray microtomography is the general platform to perform three dimensional imaging, and for producing measurements such as interfacial curvatures. To improve such curvature measurement, different image processing scenarios were tested and a novel curvature estimation method was developed. Results revealed that errors on the curvature estimates have been significantly reduced for both synthetic data and real data sets. Because curvature-based capillary pressure for disconnected non-wetting blobs differs from transducer-based capillary pressure due to residual oil blobs experience less hysteresis as well as the influence of local pore morphology, connected fluid and disconnected fluid were considered separately.

Book Synopsis Measurement of Interfacial Area Production and Permeability Within Porous Media by :

Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the pore-level interactions that affect multi-phase flow in porous media is important in many subsurface engineering applications, including enhanced oil recovery, remediation of dense non-aqueous liquid contaminated sites, and geologic CO2 sequestration. Standard models of two-phase flow in porous media have been shown to have several shortcomings, which might partially be overcome using a recently developed model based on thermodynamic principles that includes interfacial area as an additional parameter. A few static experimental studies have been previously performed, which allowed the determination of static parameters of the model, but no information exists concerning the interfacial area dynamic parameters. A new experimental porous flow cell that was constructed using stereolithography for two-phase gas-liquid flow studies was used in conjunction with an in-house analysis code to provide information on dynamic evolution of both fluid phases and gas-liquid interfaces. In this paper, we give a brief introduction to the new generalized model of two-phase flow model and describe how the stereolithography flow cell experimental setup was used to obtain the dynamic parameters for the interfacial area numerical model. In particular, the methods used to determine the interfacial area permeability and production terms are shown.
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.
