The Effect of Drainage Flow Rate on Fluid Connectivity; Application to Geologic CO₂ Sequestration

Creator:: Bertoch, Madison
Abstract:: Geologic CO₂ sequestration is a climate change mitigation strategy that involves the injection of supercritical CO₂ into deep underground rock formations. This thesis focuses on capillary trapping in which capillary forces immobilize CO₂ bubbles at the pore scale. During injection of supercritical CO₂, brine is displaced in what is known...

Viscous Effects of Wetting and Non-Wetting Fluids on Capillary Trapping Mechanism: A Climate Change Mitigation Strategy.

Creator:: Fobi, Simone
Abstract:: Rising CO₂ concentrations in the atmosphere (396 ppmv as of April 2012) increase the effect of global warming and climate change. CO₂ sequestration has become a potential method to mitigate climate change. This study focuses on capillary/residual trapping as a form of geologic CO₂ sequestration. Capillary/residual trapping occurs when supercritical...

Analyzing the Relationship between Capillary Pressure, Saturation, and Interfacial Area for a Three-Phase Flow System in Porous Media

Creator:: Paustian, Rebecca L.
Abstract:: Multi-phase flow in porous media includes many instances of subsurface flow. Three-phase flow in particular is important in situations of enhanced oil recovery, CO2 sequestration, and groundwater remediation. Many studies have been performed on how two fluid phases (oil/water or air/water) behave in porous media, but very few studies exist...

Interfacial Relaxation and Two-Fluid Flow in Porous Media: A Fast X-Ray Microtomography Study

Creator:: Meisenheimer, Douglas E.
Abstract:: The flow of multiple immiscible fluids within a porous medium controls many natural and engineered systems in the environment including: geologic CO2 sequestration, enhanced oil recovery from underground reservoirs, and contaminant remediation of groundwater. The need to understand how fluids are transported and distributed in these processes is important for...

Flow processes in the dry regime : the effect on capillary barrier performance

Creator:: Jansik, Danielle P.
Abstract:: Engineered capillary barriers typically consist of two layers of granular materials designed so that the contrast in sediment hydrologic properties and sloping interface retains infiltrating water in the upper layer. We report here on the results of two bench-top capillary barrier experiments, and associated modeling. These experiments were conducted to...

Exploring the Wettability States and Contact Angle Variation in Porous Media Multi-Phase Flow Systems

Creator:: Behnoudfar, Diba
Abstract:: The wetting of a surface by a liquid is a crucial part of many natural and industrial processes. Despite numerous existing studies, some elements of wetting-dewetting such as contact angle variation are still poorly understood. Knowledge of contact angle behavior during the flow is necessary for modeling fluid displacements in...

Linking Pore-scale Fluid-Fluid Interfacial Curvature in Porous Media to Capillary Pressure and Local Morphology with A Novel Method for Curvature Measurement

Creator:: Li, Tianyi
Abstract:: 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...

Pore-scale observations of three-fluid-phase transport in porous media

Creator:: Brown, Kendra I.
Abstract:: Understanding the transport of three fluid phases through porous media has important applications in subsurface contaminant remediation, oil and gas recovery, and geological CO₂ sequestration. Existing transport models may be improved by including physical phenomena that govern fluid flow at the pore scale. In particular, thermodynamic arguments suggest that hysteresis...

Optimization of Geologic Carbon Sequestration: Effect of Flowrate on Nonwetting Phase Connectivity

Creator:: Davis, Brittany R.
Abstract:: Atmospheric carbon reduction is arguably the most crucial facet among efforts to mitigate climate change. The Fifth International Panel of Climate Change report emphasizes a worldwide goal of maintaining global temperature elevation less than 1.5°C above pre-industrial temperatures. This report also acknowledges without the proper utilization of counteractive emission strategies...

The Effect of Flowrate on Trapping in a Two-phase System as it Relates to CO₂ Sequestration

Creator:: Williams, Kristal A.
Abstract:: This research examines the independent and combined effects of drainage and imbibition flowrate on nonwetting phase capillary trapping in a two-phase, porous medium system. A uniform system of cubic arrangement and non-uniform systems of both cubic and rhombohedral arrangements were examined in order to analyze and compare the nonwetting phase...
