The subsurface fluid mechanics of geologic carbon dioxide storage
In carbon capture and storage (CCS), CO₂ is captured at power plants and then injected into deep geologic reservoirs for long-term storage. While CCS may be critical for the continued use of fossil fuels in a carbon-constrained world, the subsurface behavior of CO₂ remains poorly understood, which …

Reduced-Order Modelling and Observations of Geological Carbon Dioxide Storage
Worldwide carbon dioxide (CO2) emissions targets are unlikely to be met without large scale geological CO2 storage, with much of the storage capacity found in saline aquifers. The key aim of carbon sequestration is the long-term or permanent storage of CO2 within the sub-surface, minimising the …

Numerical Modeling of Geologic Carbon Dioxide Storage in Faulted Siliciclastic Settings
Carbon capture and storage (CCS) is a technology where CO₂ captured from point sources or the atmosphere is injected underground for permanent storage. CCS is part of a portfolio of technologies aimed at enabling the transition to a sustainable energy system with net-zero CO₂ emissions. This Thesis …

Carbon Dioxide Storage in Coal Seams with Enhanced Coalbed Methane Recovery: Geologic Evaluation, Capacity Assessment and Field Validation of the Central Appalachian Basin
… of coalbed methane are benefits to sequestering carbon dioxide in coal seams. This is possible because of the affinity of coal to preferentially adsorb carbon dioxide over methane. Coalbed methane is the most significant natural gas reserve in central Appalachia and currently is economically …

Sequence Stratigraphy and Architecture of Lower Pennsylvanian Strata, Southern West Virginia: Potential for Carbon Sequestration and Enhanced Coal-Bed Methane Recovery in the Pocahontas Basin
Carbon dioxide sequestration in coal-bed methane fields has potential to add significant recoverable reserves and extend the production life of coal-bed methane fields while at the same time providing a geologic sink for atmospheric greenhouse gases. The ability to relate the thickness, extent, and …

Flow through porous media : from mixing of fluids to triggering of earthquakes
… recovery by displacing oil with solvents such as carbon dioxide requires development of miscibility between the two fluids to maximize the displacement efficiency. Prevention of inadvertent triggering of earthquakes due to injection or production of fluids in the underground requires understanding …

Photoporomechanics: a new technique to explore grain-scale mechanisms for fluid-driven fractures in granular media
… water dropout in fuel cells, and geological carbon dioxide storage. While fluid–fluid displacement in rigid porous media has been studied in depth, the understanding of the interplay between multiphase flow and granular mechanics remains an ongoing challenge. Photoelasticity has been used as …

Measurements, Modeling and Analysis of High Pressure Gas Sorption in Shale and Coal for Unconventional Gas Recovery and Carbon Sequestration
… order to exploit unconventional gas and estimate carbon dioxide storage potential in shale formations and coal seams, two key questions need to be initially answered: 1) What is the total gas-in-place (GIP) in the subsurface reservoirs? 2) What is the exact ratio between bulk gas content and …

Some problems in low Reynolds number environmental flows
… a few parameters. We study the fluid dynamics of carbon dioxide storage in heterogeneous aquifers, the migration of tracers in such flows and the interaction of lava flows with barriers. First, in chapter 2, we examine the injection of fluid of one viscosity and density into a horizontal permeable …

Pore-scale dynamics of immiscible two-phase flow on porous and fractured media
… liquid (NAPL) contamination of groundwater, carbon dioxide injection and storage, and enhanced oil recovery (EOR) operations. It has the potential to transform our understanding of multiphase flow processes, to improve oil and gas recovery efficiency, and to facilitate safe carbon dioxide …

Multi-scale Analysis of Methane Gas Hydrate Formation and Dissociation via Point Source Thermal Stimulation and Carbon Dioxide Exchange
… with the simultaneous injection of gaseous carbon dioxide as method of enhancing gas production rates while providing a means for long term storage of carbon dioxide in the hydrate phase. The exchange process was investigated at low and high gas injection rates under conditions of both low …

Investigating the factors impacting the success of immiscible carbon dioxide injection in unconventional shale reservoirs: An experimental study
… significant interest due to the huge hydrocarbon volumes that they bear. Enhanced oil recovery (EOR) techniques have been suggested to increase recovery from shale reservoirs. One of the most promising EOR methods is gas EOR (GEOR), most notably carbon dioxide (CO<sub>2</sub>). Not only can …
