Advances in Hydraulic Fracture Simulation - Dynamic and Quasi-static Analysis
(University of Waterloo, 2019-03-05)Hydraulic fracturing (HF) is an effective technique for permeability enhancement of conventional and unconventional reservoirs. HF is performed by injecting a fluid (usually water-based), sand, and chemicals into a formation ... -
Closed Loop Geothermal System Design
(University of Waterloo, 2022-06-17)In contrast to other renewable sources (e.g., wind and solar) that may only be intermittently available throughout a day or year, geothermal resources provide a carbon-free and sustainable source of energy for base-load ... -
Computationally Efficient Extended and Stabilized Finite Element Methods for Multiphase Carbon Sequestration Modelling
(University of Waterloo, 2016-09-01)Carbon sequestration in deep saline aquifers has been proposed for long term storage of CO2 as an alternative to the release of CO2 into the atmosphere. In this thesis a computationally efficient numerical model that ... -
Dislocation Dynamics for High Strain-Rate Plasticity: Inertial and Thermal Effects
(University of Waterloo, 2017-07-26)There has been a trend of miniaturization in recent technological advances, particularly through the development of microelectromechanical systems (MEMS). To cope with the demand for increasing performance from ever smaller ... -
Inertial, Transient, and Turbulent Flow through Deformable and Propagating Fractures: Theory and Computational Engineering
(University of Waterloo, 2023-07-20)Fluid flow in deformable fractures is important to many natural and industrial geological engineering applications including contaminant transport, geothermal energy, and hydraulic stimulation. Large-scale simulations of ... -
The Influence of Jointed Fabric and Stress Ratio on Deformation and Fluid Flow
(University of Waterloo, 2017-01-24)There are remarkable volumes of hydrocarbon resources in low-permeability naturally fractured rock masses (NFRs) characterized by naturally occurring discontinuities. Natural fractures are one of the most important factors ... -
Numerical Modeling of Nonlinear Problems in Hydraulic Fracturing: Fracture Propagation, Proppant Transport, and Shear Dilation
(University of Waterloo, 2020-05-05)Hydraulic fracturing is a stimulation technique in which fluid is injected at high pressure into low-permeability reservoirs to create a fracture network for enhanced production of oil and gas. It is the primary purpose ... -
Simulation of Hydraulic Stimulation: Acoustic Wave Emission in Fractured Porous Media Using Local and Global Partition-of-Unity Finite Element
(University of Waterloo, 2018-09-25)Hydraulic Fracturing (HF) is an effective stimulation process for extracting oil and gas from unconventional low-permeable reservoirs. The process is conducted by injecting high-pressure fluids into the ground to generate ... -
Strategically Coupled Inertial Flow and Interfaced Evolution (SCI-FIE) Models for Dissolution Mining
(University of Waterloo, 2022-08-23)Mineral dissolution or dissolution mining is a technology for underground mineral extraction. The space developed after the mining may be a desirable reservoir for the storage of natural gas and hydrocarbons or compressed ... -
Up-Scaling Distinct Element Method Simulations of Discontinua
(University of Waterloo, 2017-01-20)Pre-existing fractures significantly influence the geomechanical response of the rock mass at the reservoir scale. For geomechanical applications, these natural fractures need to be considered in the mechanical response ...
