Analytical and Experimental Study of Gas Flow Regime in the Matrix and Fractures of Shale Gas Reservoirs
DownloadFall 2016
One of the most significant differences between conventional and unconventional gas resources is the ultra-low matrix permeability of unconventional gas reservoirs such as shale, coal and tight gas. Matrix permeability of shales is an elusive but important parameter in characterizing shale gas...

Specialist predators with a limited diet may be less adaptable to environmental change than generalists, which consume a diversity of prey. As the climate changes, ecological homogenization is occurring, where generalist species outcompete specialists, reducing ecosystem complexity. In Arctic...

Analysis of Water Flowback and Gas Production Data for Fracture Characterization in the Horn River Basin
DownloadSpring 2019
Shale gas is one of the most promising energy resources due to its wide distribution, abundant reserves, and low pollutant emissions to the environment. Although shale gas plays usually have very low permeability and porosity, the use of horizontal drilling and hydraulic fracturing technologies...

Local and regional demography in a migratory forest songbird and effects of forest management intensity
DownloadSpring 2014
The numerical response of forest birds to habitat alteration has been well documented in North America, but the underlying demographic processes driving these changes remain largely unknown. Among species sensitive to such alterations, the Ovenbird (Seiurus aurocapilla) shows one of the largest...

Diagenetic Controls on Hydrothermal Fluid Flow in the Osiris, Isis, and Isis East Carlin-Type Gold Showings, Nadaleen Trend, Yukon
DownloadFall 2015
Following ATAC Resources Ltd.’s 2010 discovery of the gold prospects in the Nadaleen Trend (Central Yukon), company geologists and consultants determined that Precambrian carbonate rocks within the trend contain large endowments of gold located in the hinges of anticlines and fault zones. ...

The Structure and Dynamics of Fish Isotopic and Trophic Niches in Natural Lakes and Constructed Fisheries Offsets in the Alberta Oil Sands
DownloadFall 2022
Habitat offsets, where damages to natural ecosystems caused by socio-economic development projects are compensated for by the construction or restoration of other ecosystems, can contribute to biological conservation when implemented properly. But, large uncertainties remain surrounding our...

Isotope Geochemistry of Natural Gas from the Horn River Basin: Understanding Gas Origin, Storage and Transport in an Unconventional Shale Play
DownloadFall 2014
Devonian shales of the Horn River Basin, northeast British Columbia are recognized key targets for unconventional shale gas production in Canada. Recent studies show gas isotope geochemistry in several unconventional shale plays worldwide differ from conventional hydrocarbon reservoirs and carbon...

Factors affecting larval growth and development of the boreal chorus frog Pseudacris maculata
DownloadFall 2010
The boreal chorus frog (Pseudacris maculata) is a widespread species but we know little of its ecology. I examined the nature and existence of competitive mechanisms operating between larvae of the boreal chorus frog and wood frog (Lithobates sylvaticus) from field, mesocosm and laboratory venues...

Variations in climatic conditions from the Cayman Islands through stable isotope and element analysis from corals and sediment cores; a 500,000 year record
DownloadFall 2020
The Caribbean region is particularly important to understanding global climate change and feedback systems because the tropics are the primary source of heat and water vapor for the atmosphere. The Caribbean region, however, is a relatively understudied area in terms of tracking climate change...

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...
