Experimental and modeling evaluation of proppant transport in complex fractures
Hydraulic fracturing (HF) is widely used to stimulate and produce hydrocarbons from both conventional and unconventional reservoirs. Hydraulic fracturing creates thin but long fractures that frequently connect to pre-existing ... -
Mass transport in shale reservoirs : chemical osmosis and its impact on hydrocarbon recovery
Hydrocarbon production from nano-Darcy shale formations has become possible because of the application of multi-stage hydraulic fracturing technology on horizontal wells. During hydraulic fracturing operations, typically, ... -
Autonomous navigation in GPS denied environments using MPC and LQR with potential field based obstacle avoidance
Workers in mining industry are posed with hazardous environments due to the nature of the work inside a mine. Gas leaks, explosions, rock falls, entrapment, long exposure to dust are all potentially fatal conditions for ... -
Modeling spatial geotechnical parameter uncertainty and quantitative tunneling risks
In underground construction and tunneling (UCT) works, geological and geotechnical uncertainty is often the most significant source of risk associated with a project. Unforeseen adverse geological/geotechnical conditions ... -
Multiphysical simulation of CO₂ enhanced oil recovery in unconventional reservoirs : from fundamental physics to simulator development
The economic recovery of unconventional reservoirs is demanding yet challenging. Traditional enhanced oil recovery (EOR) techniques face difficulty when being applied to unconventional reservoirs. In this PHD study, we aim ... -
Impact of environmental conditions on methane-air explosion development and propagation through rock rubble in confined spaces , The
Methane-driven explosions in underground coal mines are among the largest and deadliest industrial explosions. Over the period from 1980-2012, CDC statistics reveal that more than 150 people died in coal mine explosions ... -
Study of colloidal transport and multiphase flow in bead-based micromodels with surface charge and wettability heterogeneities
Micromodels are porous media analogs that help scientists understand the transport phenomena in real-world porous media at the laboratory scale. Compared with traditional field- and column-scale experiments, micromodels ... -
Slope channels on an active margin : a 3D study of the variability, occurrence, and proportions of slope channel geomorphology in the Taranaki Basin, New Zealand
The study of active margin channels has become more accessible with the increased amount of high resolution three dimensional seismic surveys. Channels play an important role in sediment transport from continental region ... -
New approaches to studying shallow fault zone properties with high-resolution topography
Coseismic surface deformation fields provide us with information about the physical and mechanical properties of faults and fault zones. Recent advances in geodetic imaging and analysis allow us to map deformation and infer ... -
Interpreting sources and endocrine active components of trace organic contaminant mixtures in Minnesota lakes
On-site wastewater treatment systems (OWTSs) are a suspected source of widespread trace organic contaminant (TOrC) occurrence in Minnesota lakes. TOrCs are a diverse set of synthetic and natural chemicals regularly used ... -
Investigating halo features in ¹⁰Be with the ¹¹Be(p,d)¹⁰Be* transfer reaction at 110 MeV at TRIUMF-ISAC II
One-neutron transfer reactions are used to study single-particle neutron states in nuclei. In this work, the 11Be(p,d)10Be* transfer reaction at 9.93 MeV/nucleon was performed at the TRIUMF-ISAC II facility with the Printed ... -
Modeling, imaging and waveform-inversion in attenuative anisotropic media
Seismic attenuation, which is often anisotropic, has a profound influence on wave propagation and seismic processing. In addition to application of attenuation coefficients in lithology and fluid discrimination, compensation ... -
Bulk compositional controls on mineral assemblages in metamorphosed ore deposits : an example from the LaRonde-Penna gold-rich VHMS deposit, Quebec, Canada
The hydrothermal processes driving alteration during the formation of VHMS deposits, and therefore the overall geochemistry, mineralogy, and geometry of alteration halos, are reasonably well understood. However, less is ... -
Identifying and quantifying mountain pine beetle (Dendroctonus ponderosae) induced watershed scale changes to metal input, storage, and export, Rocky Mountains, USA
Warming climates and extended droughts enabled mountain pine beetle populations to grow and impact larger areas, as observed during the 2008-2013 widespread epidemic in the Rocky Mountain region, USA. After the decline in ... -
Investigation of the electrowinning of neodymium oxide in room temperature ionic liquid
Neodymium has widespread applications in magnets, electronics, optical and laser materials. Currently, neodymium is produced using high-temperature molten salts processes that are very energy intensive and costly. There ... -
Two-dimensional assembly of colloidal particles : fabrication and application
Over the past decades, colloidal particles with different geometric shapes, interfacial properties, and chemical compositions have been synthesized. As a result, we are able to accurately control the strength, effective ... -
Effects of anisotropic magnetic susceptibility in data interpretation and its potential in application
Anisotropic magnetic susceptibility (AMS) contains information about the internal structure of magnetic geologic units and may have the potential to provide information about the formation history and subsequent geologic ... -
Use of a look-ahead geophysical method to delineate water-bearing features ahead of a tunnel boring machine, The
In the field of underground construction and tunneling, comprehensive geologic investigations are both time-intensive and expensive, and can be logistically challenging. As such, it is common to encounter unexpected ground ... -
Mineralogy and petrogenesis of the California Blue mine aquamarine- and topaz-bearing pegmatite deposit, San Bernardino County, California
The California Blue Mine Pegmatite is a recently discovered gem aquamarine- and topaz- bearing deposit near Yucca valley in southern California, and is the first significant gem-bearing pegmatite discovered north of the ... -
Effects of alloying on nitriding behavior and fatigue performance of medium carbon bar steels
Nitriding is a surface hardening technique commonly applied to transmission gears for improved fatigue resistance. Steel alloys used for nitrided transmission components often do not have optimized compositions and thermal ...
