The Effects of Conventional Oil Wells and Associated Infrastructure on the Abundances of Five Grassland Songbird Species in Alberta’s Mixed-grass PrairieNenninger, Heather R. 31 August 2016 (has links)
Although grassland bird populations have steadily declined, little research has examined the effect of oil infrastructure on abundances of grassland songbirds. Even less research has identified mechanisms that explain observed effects. To evaluate this, I sampled abundance of 5 songbird species at oil well sites with different pump mechanisms, power sources, and activity levels; I also evaluated the effects of perch and road density and exotic vegetation, all of which are associated with oil development. Both Baird’s sparrows (Ammodramus bairdii) and Sprague’s pipits (Anthus spragueii) had lower abundances at all sites that contained oil infrastructure. The other 3 species, chestnut-collared longspurs (Calcarius ornatus), western meadowlarks (Sturnella neglecta), and Savannah sparrows (Passerculus sandwichensis), were relatively unaffected by oil wells, linear features, or exotic vegetation. Given that oil well sites negatively affected two species of concern, more research is needed to determine mitigation strategies. / October 2016

Lithofacies, Sequence Stratigraphy, and Sedimentology of Desert Creek Platform, Slope, and Basin Carbonates, Southern Margin of the Aneth Complex, Middle Pennsylvanian, Paradox Basin, UtahPerfili, Christopher M. 30 November 2020 (has links)
The Aneth Field in the Paradox Basin (SE Utah) has produced nearly 500 MMbbls of oil from phylloid-algal and oolitic carbonate reservoirs of the lower and upper Desert Creek (Paradox Formation, Middle Pennsylvanian) sequences, respectively. The oil resides in a 150 to 200 foot-thick isolated carbonate platform located in a distal ramp setting on the southwest margin of the Paradox Basin. The horseshoe-shaped platform is roughly 12 miles in diameter with an aerial extent of approximately 144 square miles. Evaluation of the platform-to-basin transition on the leeward (southern) margin of the Aneth Platform, the focus of this study, was made possible through Resolute Energy's 2017 donation of well data and core to the Utah Geological Survey Core Research Center. The lower Desert Creek sequence ranges from 50 to 100 feet in thickness and produces from a succession of phylloid-algal, boundstone-capped parasequences in the Aneth Platform. The upper Desert Creek sequence is generally thinner across the platform and is characterized by a succession of oolite-capped parasequences, except on the southern margin of the platform where it ranges from 80 to 115 feet in thickness. The upper Desert Creek thick resulted from southward shedding of platform-derived carbonate sediment and lesser amounts of quartz silt and very fine sand off the low-angle southern platform margin slope. A nine-mile-long, north-south-oriented stratigraphic panel constructed from log and core data permits characterization of thickness and facies trends through the upper Desert Creek from platform (north) to slope to distal basin (south) in the Ratherford unit. In the southern margin, five novel facies for the Aneth Field were analyzed, described, and interpreted using a sequence stratigraphic framework, all of which represent deposition on a gravity-influenced platform-edge slope. It is interpreted that the slope facies association was deposited during transgression and highstand and was generally a result of oversteepened slopes as a function of the carbonate factory on the platform being highly productive. Slope and basin facies range from proximal rudstone and floatstone to thin, graded distal turbidites, the latter of which extend at least five miles into the basin. Compaction of the muddy and fine-grained allochthonous sediment followed by pervasive calcite and anhydrite cementation has destroyed any primary porosity in the platform-derived slope-to-basin sediments.

Kurz- und langfristige Angebotskurven für Rohöl und die Konsequenzen für den MarktSchlothmann, Daniel 20 April 2016 (has links) (PDF)
In dieser Arbeit wurden Angebotskurven für 22 bedeutende Ölförderländer ermittelt und anschließend zu globalen Angebotskurven aggregiert. Gemäß den ermittelten Angebotskurven sind nahezu alle gegenwärtig in der Förderphase befindlichen Ölprojekte in den Untersuchungsländern auch beim aktuellen Ölpreis von 35 bis 40 US-$ je Barrel unter Berücksichtigung der kurzfristigen Grenzkosten rentabel. Sollte der Ölpreis jedoch in den kommenden Jahren auf diesem Niveau verharren, wird es bis zum Jahr 2024 zu einem Angebotsengpass auf dem globalen Ölmarkt kommen, da zur Deckung der zukünftigen Nachfrage die Erschließung kostenintensiver, unkonventioneller Lagerstätten und von Lagerstätten in tiefen und sehr tiefen Gewässern notwendig ist. Damit es bis zum Jahr 2024 nicht zu einem solchen Angebotsengpass kommt, ist gemäß des ermittelten langfristigen Marktgleichgewichts ein Ölpreis von mindestens 80 (2014er) US-$ je Barrel notwendig.
