Fluid flow in porous media : NMR imaging and numerical simulation
We use nuclear magnetic resonance (NMR) imaging to obtain a three-dimensional image of the pore structure in a limestone core, 4.5 mm in diameter and 10 mm in length, with a resolution of 40 [mu]m. This image is converted into boundary conditions for simulation of fluid flow through the rock using …

On relative permeability : a new approach to two-phase fluid flow in porous media
Being valid for single-phase flow, Darcy's law is adapted to two-phase flow through the standard approach of relative permeability, in which permeability, rather than being a unique property of the porous medium, becomes a joint property of the porous medium and each fluid phase. The goal of this …

Mitigating the Problem of Non-uniqueness in Fluid-flow Modeling
Modeling fluid flow in porous media is a valuable and essential tool for developing underground resources such as hydrocarbon reservoirs, groundwater aquifers, or CO₂ sequestration projects. The modeling, if done accurately, can provide a reliable forecast of future fluid behavior. However, the …

A Three-dimensional Model of Poroviscous Aquifer Deformation
… applicable to petroleum reservoirs. A porous medium saturated with water is conceptually treated in the model as a nonlinearly viscous fluid continuum. The model employs a new three-dimensional extension, made in this thesis, of Helm's poroviscosity as a constitutive law governing the …

Development of a high-order accurate reservoir simulator using spectral element method
… the future performance of a reservoir. Modeling multiphase fluid flow in porous media can be computationally challenging due to heterogeneous geologic features and sharp, moving fluid interfaces. Low-order convergence of conventional reservoir simulators, often based on finite volume or …

Rock physics investigations using pressure oscillations
… poroelastic properties is essential for simulating fluid flow in porous media. Accurate constraints on these properties have impacts on production forecasts and economics. Traditionally, transport and poroelastic properties are measured separately using, for example, the pulse-decay method to …

Using 3D Tomography to Understand Fluid-Fluid Interface Evolution in Porous Media for Carbon Sequestration Applications
Fundamental understanding of multi-phase flow in porous media is needed to deploy subsurface engineering processes such as geologic carbon sequestration (GCS) that works by injecting and storing carbon dioxide (CO2) into underground geologic formations. In this PhD project, the in-situ fluid …

LABORATORY-SCALE INVESTIGATION OF PERMEABILITY AND FLOW MODELING FOR HIGHLY STRESSED COALBED METHANE RESEROVIRS USING PULSE DECAY METHOD
The steady flow method (SFM), most commonly used for permeability measurement in the laboratory, is not applicable for tight rocks, higher rank coals and coals under highly stressed condition because of the difficulty in measuring steady-state gas flowrates resulting from the tight rock structure …

Multi-scale Investigations of Geological Carbon Sequestration in Deep Saline Aquifers
… carbon dioxide (CO2) sequestration (GCS) in deep saline aquifers is viewed as a viable solution to dealing with the impact of anthropogenic CO2 emissions on global warming. The trapping mechanisms that control GCS include capillary trapping, structural trapping, dissolution trapping, and …

Monitoring Sub-Surface Storage of Carbon Dioxide
Since 1996, super-critical CO$_2$ has been injected at a rate of $\sim$0.85~Mt~yr$^{-1}$ into a pristine, saline aquifer at the Sleipner carbon capture and storage project. A suite of time-lapse, three-dimensional seismic reflection surveys have been acquired over the injection site. This suite …
