Uncertainty quantification in seismic imaging
To make informed decisions, one has to consider all available knowledge about the assessed problem. An important part of the decision-making process is understanding uncertainties and how they influence the outcome. In ... -
Rich gas injection pilot : an enhanced oil recovery approach applied to an unconventional reservoir in the Bakken petroleum system
Economic production from shale plays focuses on hydraulic fracture techniques and well spacing optimization and yet the recovery factor ranges from 7 – 10 %. Shale plays produce large quantities of ethane and liquid rich ... -
Identification of parameters for predicting long-runout landslides in the western United States
No existing research provides an integrated analysis of the key parameters that contribute to long-runout landslides in the Western United States. This study begins the task by assembling a dataset of geological, ... -
Efficiency Optimization of a HPGe Clover Array for Implantation Decay Experiments at FRIB
The Facility for Rare Isotope Beams is a new state-of-the-art facility being built at Michigan State University in order to better understand the the fundamental building blocks of the universe. The decay station group ... -
Seismotectonics of Turkey and Iran from calibrated earthquake relocations
Uncertainties in earthquake hypocenter locations, which are counted in tens-of-kilometers in most regions of the world, are a serious limitation to seismotectonic studies. For example, they preclude individual events from ... -
Role of flashing in the formation of high-grade, low-sulfidation epithermal deposits : a case study from the Omu Camp in Hokkaido, Japan, The
The Miocene low-sulfidation epithermal Hokuryu and Omui deposits of the Omu camp in northeastern Hokkaido, Japan, are small past-producers of high-grade Au and Ag ores. The quartz textures and distribution of ore minerals ... -
Quantitative Risk Modeling of Gas Hydrate Bedding using Mechanistic, Statistical, and Artificial Neural Network Frameworks
Gas hydrates are crystalline compounds comprised of a network of hydrogen bonded water cages that can trap small gas molecules. These compounds are formed at the high pressure and low temperature conditions typically found ... -
Basic Research into Performance Improvements in Plastic Scintillator Materials for Homeland Security
Plastic scintillators are currently deployed around the world in first line radiation detectors for international borders, sensitive nuclear sites, national and academic lab settings. These scintillators are simple in their ... -
Loading and release of large protein molecules and separation of lanthanides using mesoporous materials
Protein therapeutics are promising candidates for disease treatment due to their high specificity and minimal adverse side effects; however, targeted protein delivery to specific sites has proven challenging. Mesoporous ... -
Investigation on Foam Stability and Foam-Conditioned Soil Properties under Pressure in EPB TBM Tunneling
Proper soil conditioning is very important in earth pressure balanced (EPB) tunneling as it improves face stability and tunnel boring machine (TBM) performance. Foam is one of the most commonly used soil conditioning agents ... -
Image-domain wavefield tomography in transversely isotropic media
Image-domain tomography (IDT) operates with seismic reflection data and optimizes the background velocity model by improving the quality of image gathers obtained by prestack depth migration. In this thesis, I develop an ... -
Hydrothermal evolution of Au-bearing pyrite-quartz veins and their association to base metal veins in Central City, Colorado
The Central City district played a major role in the early settlement and prosperity of Colorado, providing a major resource of Au, Ag, Cu, Pb, and Zn in the 19th century totaling more than $100 million during the time of ... -
Modeling climate change impacts to Rocky Mountain headwater hydrology
Rocky Mountain headwater catchments provide 85% of Colorado River streamflow and also feed the large Arkansas and Platte River basins. The continued growth of cities from California to Arkansas depends on reliable export ... -
Study on the Use of Cellular Cofferdam for Permanent Hydropower Use
ABSTRACT Cellular cofferdams are temporary constructions consisting of interlocking steel-sheet piling driven as a series of interconnecting cells. Cellular cofferdams have been employed mainly as provisional “water ... -
Influence of microstructure on membrane distillation : high-resolution 3D reconstructions for analysis of pore-scale phenomena, The
The demand for clean water has seen a rapid increase in the last decade; increasing the need for technological advancement in producing potable drinking water. Membrane distillation (MD) is an emerging approach for producing ... -
Fabrication, folding, and propulsion of complex colloidal molecules under applied magnetic fields
Directed colloidal assembly under external fields can be used to assemble building blocks into complicated structures that mimic complex molecules or structures found in nature with similar or even advanced functionality. ... -
Geological and Geochemical Assessment of the Sharon Springs Member of the Pierre Shale and the Niobrara Formation within the Cañon City Embayment, South-Central Colorado
The Cañon City Embayment, located in south-central Colorado, is one of the oldest and longest oil producing regions in America. Production began in 1862 after the discovery of an oil seep emanating from the Jurassic Morrison ... -
Synthesis and application of porous materials as supports for nanoparticle, single-site, and biomolecule heterogeneous catalysts
The application of porous materials as supports for catalysts has been a focus of academia and industry for many years. Mesoporous silicas (MSN) and ordered mesoporous carbons have been used due to their unique properties ... -
Nozzle design and experimental evaluation to mitigate liquid loading in gas wells
This study consists of an experimental investigation of nozzle geometry effect on critical/subcritical flow transitions with applications on liquid loading mitigation in gas wells. Experiments were conducted in a facility ... -
Heat treating response of 0.6 C steels for saw chain applications
Steels used in saw chain applications require a combination of strength, toughness, and wear resistance. The focus of this project is to develop improved steels for saw chain applications by utilizing alloying and processing ...
