Microbial enhanced oil recovery : a pore-scale investigation of interfacial interactions

Creator:: Armstrong, Ryan T.
Abstract:: Current oil production technologies recover only about one‐third to one‐half of the oil originally present in an oil reservoir. Given current oil prices, even a modest increase in oil recovery efficiency is fiscally attractive. One novel approach to increase oil recovery efficiency is a process called microbial enhanced oil recovery...

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...

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...

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...

An investigation into the pore-scale mechanisms of capillary trapping : application to geologic CO₂ sequestration

Creator:: Herring, Anna L.
Abstract:: Geologic CO₂ sequestration is a climate change mitigation strategy that prevents CO₂ emissions to the atmosphere by capturing CO₂ gasses from large point source emissions streams and then pressurizing and pumping the supercritical-state CO₂ into underground geologic storage reservoirs. Once underground, CO₂ is prevented from buoyant migration to the surface...

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...

Saturation, morphology, and topology of nonwetting phase fluid in bentheimer sandstone; application to geologic sequestration of supercritical CO2

Creator:: Herring, Anna L.
Abstract:: This work examines the impact of a viscosity force parameter, fluid velocity, and a capillary force parameter, interfacial tension, on the saturation, morphology, and topology of NW fluid in Bentheimer sandstone after primary imbibition, drainage, and secondary imbibition. Brine and air (used as a proxy for supercritical CO₂) flow experiments...

Low Level Quantification of 1,4-Dioxane and Investigation of 1,4-Dioxane Co-Metabolism by Mycobacterium sp. 1A.

Creator:: McKeage, Kevin J.
Abstract:: 1,4-Dioxane (dioxane) is a probable human carcinogen and is often found comingled with chlorinated aliphatic hydrocarbon (CAH) contamination since dioxane is used as a stabilizer in CAH solutions. Dioxane is miscible in water, has a low K[subscript ow], low H[subscript cc], and is highly recalcitrant in the environment. The presence...

Optimization of capillary trapping of CO2 sequestration in saline aquifers, Optimization of capillary trapping of CO₂ sequestration in saline aquifers

Creator:: Harper, Elizabeth J.
Abstract:: Geological carbon sequestration, as a method of atmospheric greenhouse gas reduction, is at the technological forefront of the climate change movement. During sequestration, carbon dioxide (CO₂) gas effluent is captured from coal fired power plants and is injected into a storage saline aquifer or depleted oil reservoir. In an effort...
