Methane Production and Emission Mitigation in Oil Sands Tailings Concurrent with Hydrocarbon Degradation under Nitrogen Limited Conditions
DownloadFall 2020
Alberta’s oil sands generate large volumes of tailings from bitumen ore processing. These tailings ponds produce biogenic methane, which can be measured across 60-80% of the tailings surface. Based on current surface area data and emissions studies, tailings ponds could account for 8% of Canada’s...

Collins, Catherine Elizabeth Victoria
Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...

Spring 2015
The objective of this dissertation was to find novel adsorbents addressing problems associated with acid gases. They are the most common contaminants in multiple aspects of petroleum processing and combustion gas clean up, which reduce the efficiency of petroleum refining and product quality....

Performance and Methane Emissions of RFI Selected Cattle in Drylot and Under Open Range Conditions
DownloadSpring 2018
Residual feed intake (RFI) is a moderately heritable trait that can be used to measure feed efficiency in beef cattle, and thereby reduce feed related costs. RFI has been primarily evaluated under drylot conditions where diet, feed intake and activity levels are controlled and foraging behaviour...

Fall 2017
As a follow-up method after CHOPS (Cold Heavy Oil Production with Sands), CSI (Cyclic Solvent Injection) was widely accepted in the oil industry. After injected gas solvents with high pressure are dissolved in a heavy-oil reservoir, produced oil shows dispersed gas-phase in the oil, which is...

Recovery of Legumes in Northern Temperate Pastures Following the Application of Broadleaf Herbicides
DownloadFall 2013
Field and greenhouse trials were conducted to assess the breakdown of soil residues of two broadleaf herbicide bioactives, aminopyralid and aminocyclopyrachlor, as well as associated legume reestablishment/recovery and pasture sward production dynamics. Greenhouse trials indicated legume seedling...

Relationship of Radiated Heat Loss Measured by Infrared Thermography to Residual Feed Intake in Beef Heifers
DownloadFall 2013
Infrared thermography (IRT) has shown utility in predicting residual feed intake (RFI) differences in mature cows, growing bulls and finishing steers. It was hypothesized that efficient heifers would exhibit decreased radiated heat loss. RFIfat determined on sixty-one crossbred beef heifers over...

Reservoir and geomechanical coupled simulation of CO2 sequestration and enhanced coalbed methane recovery
DownloadFall 2009
Coalbeds are an extremely complicated porous medium with characteristics of heterogeneity, dual porosity and stress sensitivity. In the past decades great achievements have been made to the simulation models of pressure depletion coalbed methane (CBM) recovery process and CO2 sequestration and...

Social Contexts of Environmental Practices: How Sustainable Development Discourses and Trust Mediate the Use of Genomics in the Alberta Beef Industry
DownloadFall 2014
In the face of environmental degradation resulting from beef production, genomics may add to the options available to producers seeking to reduce their environmental impacts. This research seeks to understand cow/calf producer experiences with the environment, the environmental impacts of their...

Stream Carbon Flux in the Northern Pacific Coastal Temperate Rainforest: Seasonal DOC Transport and CO₂ and CH₄ Emissions
DownloadSpring 2020
Streams in British Columbia's humid, organic-rich Pacific Coastal Temperate Rainforest (PCTR) deliver globally significant yields of soil-derived dissolved organic carbon (DOC) to the ocean, which can affect ocean acidification, provide energy to coastal food webs, and off-gas to the atmosphere...
