Pore-scale observations of supercritical CO₂ drainage in Bentheimer sandstone by synchrotron x-ray imaging

Creator:: Herring, Anna L., Andersson, Linnea, Newell, D. L., Carey, J. W., and Wildenschild, Dorthe
Abstract:: This work utilizes synchrotron-based x-ray computed microtomography (x-ray CMT) imaging to quantify the volume and topology of supercritical carbon dioxide (scCO₂) on a pore-scale basis throughout the primary drainage process of a 6 mm diameter Bentheimer sandstone core. Experiments were performed with brine and scCO₂ at 8.3 MPa (1200 psi)...

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...

Visualization and characterization of biofilm spatial distribution in porous media using x-ray computed microtomography

Creator:: Iltis, Gabriel C.
Abstract:: This work focuses primarily the development of methods for imaging microbial biofilms in opaque porous media using x-ray computed microtomography (CT). Two methods for evaluating biofilms in porous media are presented. The first focuses on the addition of silver-coated, hollow glass microspheres to a biofilm-containing micro-model. The silver-coated microspheres affix...

X-ray imaging and analysis techniques for quantifying pore-scale structure and processes in subsurface porous medium systems

Creator:: Wildenschild, Dorthe and Sheppard, Adrian P.
Abstract:: We report here on recent developments and advances in pore-scale x-ray tomographic imaging of subsurface porous media. Our particular focus is on immiscible multi-phase fluid flow, i.e., the displacement of one immiscible fluid by another inside a porous material, which is of central importance to many natural and engineered processes....

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...

Pore-scale displacement mechanisms as a source of hysteresis for two-phase flow in porous media

Creator:: Schlüter, S., Berg, S., Rücker, M., Armstrong, R. T., Vogel, H., Hilfer, R., and Wildenschild, D.
Abstract:: The macroscopic description of the hysteretic behavior of two-phase flow in porous media remains a challenge. It is not obvious how to represent the underlying pore-scale processes at the Darcy-scale in a consistent way. Darcy-scale thermodynamic models do not completely eliminate hysteresis and our findings indicate that the shape of...

Investigating capillary pressure and interfacial area for multiphase flow in porous media using pore-scale imaging and lattice-Boltzmann modeling

Creator:: Porter, Mark L.
Abstract:: 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....

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...

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...

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...
