An Engineering Study To Investigate The Methane Hydrate Resource Potential Associated With The Barrow Gas Fields In Alaska, Praveen Kumar Singh

Engineering

"Previous studies on the Barrow Gas Fields (BGF) in Alaska have suggested that accumulations of natural gas hydrates could exist within these reservoirs. In consideration of future energy challenges, and the potential of gas hydrates in meeting them, a comprehensive engineering study was undertaken to investigate the BGF for hydrates, and to recommend an optimal plan for future field development. The methane hydrate resource potential of the BGF, viz. the East Barrow (EB), South Barrow (SB), and Walakpa (WAL) gas pools, was analyzed by developing gas hydrate stability models. Material balance studies were performed on the EB gas field to …

Geologic Setting Of The Central Alaskan Hot Springs Belt: Implications For Geothermal Resource Capacity And Sustainable Energy Production, Amanda M. Kolker

Geosciences

The Central Alaskan Hot Springs Belt (CAHSB) is a vast stretch of low-temperature hydrothermal systems that has the potential to be a geothermal energy resource for remote communities in Alaska. Little exploration has occurred in the CAHSB and the resource is poorly understood. A geothermal power plant was installed in 2006 at Chena Hot Springs (CHS), one of the 30-plus hot springs in the CAHSB. This, in addition to the multiple direct use projects at CHS, could serve as a model for geothermal development elsewhere in the CAHSB. This dissertation evaluates the geologic setting of the CAHSB and explores the …

The Earthquake Cycle Of Strike-Slip Faults, Gina M. Schmalzle

Open Access Dissertations

An earthquake is a mechanism of stress release along plate boundaries due to relative motion between the Earth's lithospheric blocks. The period in which stresses are accruing across the plate boundary is known as the interseismic portion of the earthquake cycle. This dissertation focuses on interseismic portion of the earthquake cycle to extract characteristics of fault, shear zone and rock properties. Global Positioning System (GPS) data are used to observe the pattern of deformation across two primarily strike-slip fault systems: the Carrizo Segment of the San Andreas Fault (SAF) and the Eastern California Shear Zone (ECSZ). Two sets of GPS …

Investigating The Margins Of Pleistocene Lake Deposits With High-Resolution Seismic Reflection In Pilot Valley, Utah, John V. South

Theses and Dissertations

A vast area of the northeastern Great Basin of the western USA was inundated by a succession of Plio-Pleistocene lakes, including Lake Bonneville (28 ka to 12 ka). The Pilot Valley playa, located just east of the Utah-Nevada border near Wendover, Utah, within the eastern Basin and Range Province, represents an 8 to 16 km wide and ~50 km long remnant of these lakes. The playa corresponds to the upper surface of a closed basin that is delimited by two mountain ranges, which are mantled by recent alluvial fans over which the playa sediments have prograded. In order to investigate …

The Virtual Landscape Of Geological Information Topics, Methods, And Rhetoric In Modern Geology, Sarah Elizabeth Fratesi

USF Tampa Graduate Theses and Dissertations

Geology is undergoing changes that could influence its knowledge claims, reportedly becoming more laboratory-based, technology-driven, quantitative, and physics- and chemistry-rich over time. This dissertation uses techniques from information science and linguistics to examine the geologic literature of 1945-2005. It consists of two studies: an examination of the geological literature as an expanding network of related subdisciplines, and an investigation of the linguistic and graphical argumentation strategies within geological journal articles.

The first investigation is a large-scale study of topics within articles from 67 geologic journals. Clustering of subdiscipline journals based on titles and keywords reveals six major areas of geology: …

Analysis Of Dam Behaviour After Eighty Years Of Service, Paolo Croce, Giuseppe Modoni

International Conference on Case Histories in Geotechnical Engineering

The paper reports on the behaviour of a masonry dam built in the Italian Alps in the early twenties of the last century and still in operation for electric power supply. The dam is 31 m high and its waterproofing is ensured by a multi-layered impervious facing, a concrete cut-off and a grout curtain protruding into the foundation soils. The geological location of the dam is rather complex, because its left abutment is located on a rock formation while the right one rests on a thick moraine deposit. Since its first impounding, large downstream water flows and significant movements of …

Separation And Characterization Of Respirable Amphibole Fibers From Libby, Montana, James S. Webber, David J. Blake, Tony Ward, Jean C. Pfau

Public and Community Health Sciences Faculty Publications

The vermiculite mine in Libby, Montana, was in operation for over 70 yr and was contaminated with asbestos-like amphibole fibers. The mining, processing, and shipping of this vermiculite led to significant fiber inhalation exposure throughout the community, and residents of Libby have developed numerous pulmonary diseases such as lung cancer and mesothelioma. The present study describes the separation of Libby 6-mix into respirable and nonrespirable size fractions by means of aqueous elutriation. The elutriator, designed to separate fibers with aerodynamic diameters smaller than 2.5 μm (respirable) from larger fibers, used an upward flow rate of 3.4 × 10^{−4 …}

Petrobras Examining Potential New Oil-Field Discovery, Notisur

NotiEn: An Analytical Digest About Energy Issues in Latin America

Brazil's state-owned oil company Petroleo Brasileiro S.A. (Petrobras) may have discovered another site of massive offshore oil reserves just months after it announced the largest petroleum discovery in years. If tests show that the offshore deposit in the Espirito Santo field in the Atlantic Ocean contains as much as early reports claimed, it would be the world's third-largest reserve and the world's biggest discovery in decades. Carioca four times bigger than Tupi? In the final months of 2007, Petrobras announced the discovery of 5 billion to 8 billion barrels of oil and natural-gas reserves at the offshore Tupi field.

Got Water? Limiting Washington's Stockwatering Exemption To Five Thousand Gallons Per Day, Kara Dunn

Washington Law Review

In Washington, a comprehensive groundwater code governs groundwater withdrawals and use. This regulatory scheme protects water users, minimizes disputes over water rights, and maximizes the beneficial use of public water resources. Despite these protections, groundwater resources are declining in many parts of the state. Washington exempts certain types of small withdrawals from the groundwater code’s regulations, including water for livestock. Conflicting interpretations of this stock-watering exemption have created uncertainty over whether exempt stock-watering withdrawals are unlimited, or are limited to 5000 gallons per day. This Comment analyzes the conflicting interpretations of the groundwater exemption statute under Washington’s rules of statutory …

Geology Of The Southern Reveille Range, Nye County, Nevada, Matthew Alan Mckelvey

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Reveille Range in central Nevada provides a unique window into the mid-Miocene geology and volcanology of the central Great Basin during the "ignimbrite flare up." Although faulted along its margins, the interior of the range is relatively undeformed thus preserving volcanic centers. The Reveille Range contains three mid-Miocene caldera complexes. Previous studies have identified the Goblin Knobs caldera (25.6 Ma) in the central Reveille Range and the caldera of northern Reveille Range (25.3 Ma) to the north. These calderas are completely filled with intracaldera tuffs. This study has identified a younger third caldera located in the southern part of …

Provenance Analysis Of The Cretaceous Pythian Cave Conglomerate, Northern California, Gregory Alan Augsburger

Earth and Environmental Geosciences Student Honors Theses

Reconstructions of the Mesozoic paleogeography of the North American Cordillera depend on data that can link displaced terranes to each other and/or to the North American craton. The Pythian Cave Conglomerate (PCC) sits unconformably on the eastern terranes of the Klamath Mountains south of Yreka, California and has the potential to yield valuable information about the tectonic history of the region. The PCC is approximately 60 m thick, with the lower 40 m dominated by cobble conglomerate with thin sandstone lenses, and the upper 20 m containing thicker and more laterally continuous interbedded sandstone layers. Originally interpreted as Tertiary conglomerate …
