▼ Populations of organisms are influenced by both top-down (predator driven) and bottom-up (environment or resource driven) effects. Seabird research has largely focused on bottom-up factors influencing reproduction, with little emphasis on top-down. Our goal was to better understand top-down impacts on colonial nesting seabirds over a range of spatio-temporal scales. We studied the coast-wide distribution and abundance of a Common Murre (Uria aalge) metapopulation during two decades (1988-2006) of Bald Eagle (Haliaeetus leucocephalus) recovery in Oregon. Bald Eagles prey on seabirds, but were functionally absent during much of the 20th century. After eagles were protected under the U.S. Endangered Species Act in 1978, populations increased rapidly especially along the coast where eagles cause disturbance at seabird colonies. We also studied the effects of predation and disturbance in 2012 at three Common Murre breeding sites located in regions of varying Bald Eagle density, and at a single site over a seven year period from 2007-2013. We found regional changes in the distribution and abundance of Common Murres at breeding sites in Oregon associated with increases in coastal Bald Eagle nests over 20 years of study. Coast-wide Bald Eagle nest density was not uniform. The highest Bald Eagle nest density was found on the north coast, intermediate density on the central coast, and lowest density in on the south coast throughout the study. On the north coast, counts of murres declined by 50% between 1988 and 2006. In contrast, the number of murres counted and the number of breeding sites occupied increased substantially on the central coast, where Bald Eagle nest density was lower. Changes in the number and size of murre colonies on the north and central coast were associated with the regional density of Bald Eagle nests and initial number of murres present at each site, rather than immediate proximity of eagle nests to murre colonies. Bald Eagles were the main predators causing disturbance at individual breeding sites studied. In 2012, we found differences in disturbance frequency, colony disruption, and predator activity among three sites in regions of high, medium and low Bald Eagle abundance. Eagles caused complete reproductive failure at the north coast site (high eagle density) in 2012. In addition to Bald Eagles, California Brown Pelicans (Pelecanus occidentalis) caused disturbance at the central and south coast sites, leading to low reproductive success and failure of remaining chicks at these sites in July 2012. We found no difference in reproductive loss between disturbances caused by adult and sub-adult eagles however, secondary nest predators (gulls, corvids and vultures) had a greater overall impact on reproductive loss than primary predators. From 2007-2013, we found a negative association between mean reproductive success of murres and mean rate of eagle disturbance. Our observations provide evidence for top-down regulation of breeding populations of Common Murres in Oregon, mediated by recently recovered… Advisors/Committee Members: Dugger, Katie M.

▼ According to the 2011 Energy Information Agency (EIA) global assessment, Mexico ranks 4th in shale gas resources. The Eagle Ford shale is the formation with the greatest expectation in Mexico given the success it has had in the US and its liquids-rich zone. Accurate estimation of the resource size and future production, as well as the uncertainties associated with them, is critical for the decision-making process of developing shale oil and gas resources. The complexity of the shale reservoirs and high variability in its properties generate large uncertainties in the long-term production and recovery factors of these plays. Another source of uncertainty is the limited production history. Given all these uncertainties, a probabilistic decline-curve analysis approach was chosen for this study, given that it is relatively simple, it enables performing a play-wide assessment with available production data and, more importantly, it quantifies the uncertainty in the resource size. Analog areas in the US Eagle Ford shale were defined based on available geologic information in both the US and Mexico. The Duong model coupled with a Markov Chain Monte Carlo (MCMC) methodology was used to analyze and forecast production of wells located in the previously defined analog sectors in the US Eagle Ford shale. By combining the results of individual-well analyses, a type curve and estimated ultimate recovery (EUR) distribution for each of the defined analog sectors was obtained. These distributions were combined with well-spacing assumptions and sector areas to generate the prospective-resources estimates. Similar probabilistic decline-curve-analysis methodology was used to estimate the reserves and contingent resources of existing wells. As of March 2013, the total prospective resources (P90-P50-P10) for the Eagle Ford shale in Mexico (MX-EFS) are estimated to be 527-1,139-7,268 MMSTB of oil and 17- 37-217 TSCF of gas. To my knowledge, this is the first oil estimate published for this formation in Mexico. The most attractive sectors based on total estimated resources as well as individual-well type curves are located in the southeast of the Burgos Basin and east-west of the Sabinas basin. Because there has been very little development to date, estimates for reserves and contingent resources are much lower than those for prospective resources. Estimated reserves associated with existing wells and corresponding offset well locations are 18,375-34,722-59,667 MMSCF for gas and zero for oil. Estimated contingent resources are 14-64-228 MSTB of oil and 8,526-13,327- 25,983MMSCF of gas. The results of this work should provide a more reliable assessment of the size and uncertainties of the resources in the Mexican Eagle Ford shale than previous estimates obtained with less objective methodologies.

▼ The aim of this study was to develop an understanding of the Eagle Ford shale unpropped and propped fracture conductivity. Samples were collected at Antonio Creek and Lozier Canyon. Both outcrops are several hundred feet thick and extend for a few thousand feet laterally. At these locations five different geological facies (A, B, C, D and E), each with distinct lithological characteristics and geochemical properties that can be correlated to the Eagle Ford shale in the subsurface are accessible. The mineralogy of the collected samples was determined via x-ray diffraction which corroborates the relationship of the samples to the outcrops and hence to the Eagle Ford shale in the subsurface. After collected, the samples were cut into modify API conductivity cell dimensions. The fracture conductivity at different closure stresses was determined based on laboratory measurements of flow rate and pressure drops along the fracture. The fluid used in this work was nitrogen. The proppant concentration used is representative of what is commonly used in hydraulic fracturing treatments in the Eagle Ford shale. The heterogeneity of the Eagle Ford shale is addressed by obtaining conductivity samples in two different directions with respect to the bedding plane for the five geological facies. Three directions were obtained for facies B. Fracture area and fracture roughness (surface attributes) were calculated from the data taken by a surface profilometer. The mechanical properties, namely Young’s modulus, Poisson’s ratio and Brinell hardness, were experimentally determined from core plugs acquired from the same rocks where the conductivity samples were obtained. The effect that the surfaces attributes, mechanical properties and geological facies (mineralogy) have on conductivity was analyzed and the major findings of this work are the following. From this study, we found that fracture orientation has an impact on the fracture conductivity. It was also found that the geological characteristics (mineralogy) and mechanical properties (Poisson’s Ratio) impact the fracture conductivity. The geological facies (lithology) impact the fracture conductivity in Eagle Ford shale. Facies A, B and C exhibit a good relationship between fracture conductivity and surface attributes (fracture roughness and area). This relationship is not present in facies D and E. This work provides a foundation for future studies (damage mechanism) of the Eagle Ford shale fracture conductivity and gives an insight into the relationship of fracture conductivity and geological facies.

▼ In previous works and published literature, production forecast and production decline of unconventional reservoirs were done on a single-well basis. The main objective of previous works was to estimate the ultimate recovery of wells or to forecast the decline of wells in order to estimate how many years a well could produce and what the abandonment rate was. Other studies targeted production data analysis to evaluate the completion (hydraulic fracturing) of shale wells. The purpose of this research is to generate field-wide production forecast of the Eagle Ford Shale (EFS). This study considered oil production of the EFS only. More than 6 thousand oil wells were put online in the EFS basin between 2008 and December 2013. The method started by generating type curves of producing wells to understand their performance. Based on the type curves, a program was prepared to forecast the oil production of EFS based on different drilling schedules; drilling requirements can be calculated based on the desired production rate. To complement the research, analysis of daily production data from the basin was performed. Moreover, single-well simulations were done to compare results with the analyzed data. Findings of this study depended on the proposed drilling and developing scenario of EFS. The field showed potential of producing high oil production rate for a long period of time. The three presented forecasted cases gave and indications of the expected field-wide rate that can be witnessed in the near future in EFS. The method generated by this study is useful for predicting the performance of various unconventional reservoirs for both oil and gas. It can be used as a quick-look tool that can help if numerical reservoir simulations of the whole basin are not yet prepared. In conclusion, this tool can be used to prepare an optimized drilling schedule to reach the required rate of the whole basin.

▼ The Upper Cretaceous in Texas is a proven prolific hydrocarbon system. The “Eaglebine” in Central Texas, which includes both the Eagle Ford and Woodbine intervals, is an emerging play with promising results. However, stratigraphic architecture in this region is poorly understood when compared to that of the Maverick Basin and East Texas Basin. The objective of this research is to narrow the stratigraphic uncertainties of Woodbine-Eagle Ford correlation between the East Texas and Maverick Basins and to predict the distribution of sand bodies in the active “Eaglebine” interval in Leon, Madison, Grimes and Brazos Counties by integrating information from available wireline logs and cores. A new stratigraphic interpretation of this region is proposed, and estimates of the petrophysical properties for the potential hydrocarbon-bearing intervals in the study area are presented. The Buda Limestone-Austin Chalk succession in this study area, which brackets the “Eaglebine”, thins westward due to uplift associated with the San Marcos Arch and erosion at the Base Austin Chalk (BAC) Unconformity. Wireline log interpretation suggests that Woodbine Group sediments, which are dominantly siliciclastic, are a little over 500 feet (152.5) thick updip in Leon County and thin dramatically to fifty feet (15.25 m) thick downdip in Brazos County. This transition records the Woodbine shelf break in Leon-Madison County area. The unconformably overlying Lower Eagle Ford Formation is relatively thick in Brazos and Grimes Counties. The lower part of the Lower Eagle Ford Formation is carbonate-rich shale with high gamma ray and formation resistivity. This unit has the potential to be a prolific play in Brazos and Madison Counties. The Upper Eagle Ford Formation in this region is a mixture of siliciclastic and carbonate sediments. The proportion of carbonate sediments gradually increases upwards to the Base Austin Chalk Unconformity. The sandstones of Upper Eagle Ford Formation have good hydrocarbon reservoir potential based on their non-shale porosity values and high sand percentage. This study resolves the stratigraphic architecture of the Upper Cretaceous Woodbine-Eagle Ford interval in the study area and will be helpful in understanding the regional stratigraphy from the East Texas Basin to the Maverick Basin when integrated with seismic data.

▼ This thesis investigates the impacts of diagenesis on the Late-Cretaceous Eagle Ford Formation (Fmn) in south-west Texas. This was achieved utilising many techniques such as of outcrop and core analysis, standard petrographic techniques (including cathodoluminescence [CL] and scanning electron microscopy [SEM]), and geochemical analysis (x-ray diffraction [XRD], stable isotope analysis of C and O within inorganic minerals and Rock Eval pyrolysis). The bulk of diagenetic products and textures were identified via petrographic techniques, with geochemical analysis confirming interpretations based on visual observations. This thesis shows the Eagle Ford Fmn is a calcareous, organic-rich mudstone containing eight distinct lithofacies, which have all been directly impacted by burial diagenesis. The Lower Eagle Ford Fmn mainly comprises of dark organic and clay-rich lithofacies which represent a classic source rock with interbedded carbonate rich lithofacies. The Upper Eagle Ford Fmn is organic and clay-poor, with the bulk of lithofacies carbonate dominated and heavily cemented. An initial anoxic, open marine depositional environment which transitions into an oxic deepening environment is inferred during deposition of the Eagle Ford Fmn. Early, microbial derived redox reactions have precipitated authigenic calcite and pyrite within the Eagle Ford Fmn. Authigenic calcite infills and preserves biogenic debris (mainly planktonic and benthic foraminifera), with pyrite framboids post-dating the carbonate cements. Kaolinite infilling biogenic debris is also a common occurrence indicating it is also an early diagenetic product. Smectite is converted to mixed layer I/Sand illite during deep burial processes at similar depths and temperatures to hydrocarbon generation and expulsion. Authigenic quartz cements precipitate within primary porosity and on top of carbonate cements. Chlorite is observed as the last mineral precipitated in the Eagle Ford Fmn, often pseudomorphed from kaolinite within the micritic matrix. Diagenesis has had the greatest impact on porosity distribution in the Eagle Ford Fmn. The organic, clay-rich lithofacies contain little intra/inter-crystalline porosity with the bulk observed as clay-held or organic porosity. Meanwhile the carbonate-rich lithofacies contain mainly intra-crystalline porosity. Concretions are a common feature observed in the Lower Eagle Ford Fmn outcrops. Four concretion types were identified and studied using a variety of petrological and geochemical techniques. Diagenesis plays a major role in all concretions types. However, primary factors such as sea level fluctuation, sediment input and tectonic activity also have key impacts on the formation of concretions.

▼ Mexico’s oil and gas production decline from conventional reservoirs calls for the assessment of their Late Cenomanian-Turonian shale resources. However, a geological screening of the Texas Gulf coast and east and northeast Mexico indicates that their distinct paleogeographic and tectonic development preclude a straightforward correlation between the Upper Cretaceous Eagle Ford Group of Texas and equivalent formations in Mexico. In Texas, east of the Frio River Line, extensional tectonics prevailed during the Mesozoic-Cenozoic; while in Mexico compressional tectonics influenced sedimentation from the late Cenomanian through the Eocene. Late Cenomanian compression led to paleobathymetry variations that may have influenced the lithology, distribution, and thickness of the lower organic-rich interval of the Eagle Ford Group, as well as the uplift of a western landmass that was a source of detrital argillaceous sediments. Laramide orogeny produced the exhumation of the late Cenomanian-Turonian section in most of the eastern part of Mexico, and its burial in foreland basins below Cenozoic sediments with contrasting thickness. Therefore, uplift and loading burial impacted critical depth-dependent factors such as thermal maturation, pore pressure, and viscosity. Hence, in east and northeast Mexico four areas have geological and geotechnical characteristics to be potential sweet spots in the Eagle Ford trend. The areas are the Sabinas Coal Basin, the western part of the Burgos Basin, the southwestern part of the Maverick Basin, and the southwestern part of the Tampico-Misantla Basin. Each area may be an opportunity to ensure Mexico´s energy mix and offset the declining production; nevertheless, these areas present significant technical, operational, and public challenges such as water shortage or mismanagement, insufficient road and pipeline infrastructure, and the ability to deal with people with strong cultures and social roots. Once the geologic and engineering data extracted from the appraisal wells permit the understanding of the economic potential of the sweet spots, supply chains may develop around a Northeastern Hub embracing the Burgos, Maverick, and Sabinas Coal Basins, and an Eastern Hub, including the Tampico-Misantla Basin. High-quality project management and decision-making process based on economic and scientific facts may permit a fruitful learning curve. Advisors/Committee Members: Tinker, Scott W.

▼ The loss of habitat to agriculture is a worldwide problem for biodiversity conservation. One species that has seemingly been able to adapt to the conversion of forests to farmlands is Mackinder’s eagle owl (Bubo capensis mackinderi), which inhabits highland areas, but little is known of its ecology, especially outside of protected areas. This study examined the impact of agricultural practices and farmer’s attitudes on the foraging and population ecology of the Mackinder’s eagle owl in central Kenya. Owl territories were monitored monthly from June 2004- October 2006 for signs of occupancy, breeding activity, mortality and to collect data on food resources. Nest site characteristics were measured for all known nests. Because previous studies showed an affinity for rodents, small mammals were trapped monthly using mark-recapture methodology. In each territory, the type and amount of farm crops were measured each month and farmers were interviewed about their knowledge and beliefs about owls. Mackinder’s eagle owls in central Kenya lived at extremely high density 0.87 owl pairs/km². This density was high compared to other populations of Mackinder’s eagle owl and to Eurasian eagle owl (Bubo bubo) populations in Europe. Breeding success was 48% over three years and this compared well with other species of eagle owl inhabiting human-disturbed areas. All nests and roosts were located in river valleys, and all successful nest sites were located on cliffs or other inaccessible rocky terrain. Nest sites were located adjacent to farms, which provided for both open hunting and an abundance of prey. Breeding activity was concentrated after the rainy seasons and this was likely linked to prey availability after the rains. Agricultural activities generally had a positive effect on rodent populations. Small mammal trapping results revealed that rodents were over 14 times more abundant in farms than in adjacent grassland habitat. This population of Mackinder’s eagle owl had a very catholic diet and consumed mostly mammalian prey species including hares, giant rats, root rats, grooved-tooth rats and small rodents. Small rodents accounted for almost half of the owls’ diet and when their numbers increased, owls responded by consuming more of them, indicating the importance of farming activities to this population of owls. Other populations of eagle owl inhabiting human-disturbed areas had diet widths positively related to levels of habitat disturbance. This result supported optimal foraging theory that more productive environments have predators with more specialized diets, while patchy environments have generalist predators. The ecology of this population of Mackinder’s eagle owls was heavily influenced by human agricultural activities, which generally had a positive effect on their population. Farming activities changed rapidly both within and between seasons as plots were small and neighbouring farmers planted various crops at different times of the year and this was enhanced by irrigation in some areas. Year-round availability of… Advisors/Committee Members: Craig, Adrian.

▼ Hydraulic fracturing is a well completions technique that induces a network of flow channels in a reservoir. These channels are characterized by fracture conductivity, a measure of how easily a liquid or gas flows through the fracture. Fracture conductivity is influenced by several variables including fracture surface roughness, fracture closure stress, proppant size, and proppant concentration. The proppant concentration within a fracture can significantly affect the magnitude of fracture conductivity, which enhances the productivity of a hydraulically fractured well. Therefore, understanding the relationship between proppant concentration and fracture conductivity is critical to the successful development of unconventional reservoirs such as the Eagle Ford Shale. This work investigates the fracture conductivities of seven Eagle Ford Shale samples collected from an outcrop of facies B. Rough fractures were induced in the samples and laboratory experiments that closely followed the API RP-61 procedure were conducted on the samples to measure the unpropped and propped conductivities. Propped experiments were performed with 30/50 mesh white sand at two different areal concentrations within the fracture, 0.1 lb/ft^(2) and 0.2 lb/ft^(2). Assuming a cubical packing arrangement, the proppant pack is calculated to be a partial monolayer of 0.8 layers at 0.1 lb/ft^(2) and a pack of 1.6 layers at 0.2 lb/ft^(2). The results show that when the fractures are propped with 0.1 lb/ft^(2) or 0.2 lb/ft^(2), fracture conductivity values are approximately two orders of magnitude greater than unpropped conductivity values. Therefore, even low areal concentrations of proppant in a fracture can significantly enhance conductivity in the Eagle Ford Shale. Comparing the results of the two propped experiment types, conductivity values at 0.1 lb/ft^(2) proppant concentration are on average 49% higher than conductivity values at 0.2 lb/ft^(2). This difference is attributed to the partial monolayer pack at 0.1 lb/ft^(2) and proppant pack of 1.6 layers at 0.2 lb/ft^(2). However as closure stress increases from 1,000 psi to 6,000 psi, fracture conductivity at 0.2 lb/ft^(2) decreases more slowly than conductivity at 0.1 lb/ft^(2). These results suggest that the conductivity of the denser proppant pack at 0.2 lb/ft^(2) is more resistant to the flow inhibiting effects caused by proppant embedment and proppant crushing.

▼ Hydraulic fracture treatments are used in low permeability shale reservoirs in order to provide highly conductive pathways from the reservoir to the wellbore. The success of these treatments is highly reliant on the created fracture conductivity. Optimizing fracture designs to improve well performance requires knowledge of how fracture conductivity is affected by rock and proppant characteristics. This study investigates the relationship between rock characteristics and laboratory measurements of propped and unpropped fracture conductivity of outcrop samples. These samples are from the Eagle Ford shale and the Fayetteville shale. Triaxial compression tests were performed on core specimens in order to determine the Young’s Modulus and Poisson’s Ratio of the outcrop samples. A combination of X-ray diffraction and Fourier transform infrared spectroscopy was used to determine the mineralogy. Profilometer surface scans were also performed to characterize the fracture topography. The results from this study show that the main factors affecting fracture conductivity are closure stress and proppant characteristics (concentration, size, and strength). For unpropped fractures, the fracture topography is the main factor in determining fracture conductivity. The topography interaction of the two surfaces determines the fracture width. A higher Young’s Modulus helps maintain this fracture width by resisting deformation as closure stress increases. For propped fractures, the most influential factor in determining fracture conductivity is proppant characteristics (concentration, size, and strength). At a proppant monolayer placement, the major mechanism for conductivity loss is proppant embedment, leading to decreased fracture width. A higher Young’s Modulus reduces the proppant embedment and better maintains fracture conductivity as closure stress increases. For a multilayer proppant pack concentration, the effect of rock characteristics is negligible compared to the effect of proppant pack characteristics.

▼ Food habits and levels of organochlorine compounds, lead, and mercury in resident and wintering bald eagles were studied in southcentral Oregon and California, 1979-83. Food habits were assessed by examination of castings from winter communal roosts, identification of 2938 prey items found at nest sites and foraging areas, and observations of 16 eagles with radios. Contaminant residues in prey were determined by analyses of 290 pooled samples of potential prey. Contaminant residues in eagles were determined by analyses of 13 addled eggs, blood samples from 24 adults, 8 sub-adults, and 82 nestlings, and carcasses of 11 eagles. Non-resident eagles concentrated in the southern Klamath Basin during winter months and fed largely on microtine rodents and cholera-killed dabbling ducks and geese. Contaminant residues in samples of prey from the wintering area were low with the possible exception of lead shot in waterfowl, which presented a potential for lead poisoning in eagles. Wintering bald eagles did not have elevated body burdens of organochlorines which have been associated with reproductive problems. Diets of resident eagles in southcentral Oregon were highly diverse, changed seasonally, and differed markedly by geographic region. Eagles fed largely on fish during summer months with the importance of ducks and fish-eating birds increasing during the fall and late winter. Most prey of resident eagles were taken live or pirated from osprey; scavenging comprised less than 20% of the observed predation. Contamination of the majority of the prey of resident bald eagles was fairly low. However, DDE, PCBs, and mercury were consistently detected at moderate levels and indicated biomagnification in the food-chain. Fish-eating birds in the eagles' diets were apparently the source of elevated environmental contaminants in the eagles on Upper Klamath Lake. Concentrations of DDE in eagle blood and eggs indicated that reproductive success of specific nest sites in the Klamath Basin was reduced. Although contamination was not at levels associated with critical population declines, its effects should not be discounted considering the number and severity of other factors impinging on eagle populations.

▼ This study utilizes three cores provided by Devon Energy from LaVaca and Dewitt Counties, TX, which were analyzed with a focus on diagenetic fabrics within the Lower Eagle Ford. A better understanding of paragenesis within the organic-rich Lower Eagle Ford was developed with the use of XRF and XRD measurements, thin section samples, stable isotope analysis, and CL analysis. The majority of diagenetic alteration occurred early at shallow depths within anoxic/suboxic environments and slightly sulfate-reducing conditions from diagenetic fluids with varying isotopic composition. Diagenetic expression variation is most influenced by the depositional facies in which alteration occurs. Within the study area, four identified depositional facies (A-D), and five diagenetic facies (1-5) were identified within the Lower Eagle Ford study area based on recrystallization, crystalline growth pattern, and elemental composition. Four of these facies were determined to significantly alter the character of the rock through recrystallization. The majority of recrystallized forms within the Lower Eagle Ford are expressions of pervasive growth recrystallization occurring within foraminifera-rich layers. Elemental analyses of these pervasive forms indicates that foraminifera-rich beds that underwent recrystallization contain abundant clays (indicated by relatively high Al) that can be correlated to the diagenetic expression. Early diagenesis preserved foraminifera tests, but multiple phases of diagenesis are apparent in these recrystallized forms where clays served as the conduit for diagenetic fluids. Stable isotope values ranging from δ¹³ C (-7 to+2 ‰) and δ¹⁸ O ranges of (-5.25 to -2.25 ‰), depleted from organic carbon in samples, indicate a range of isotopic composition with possible mixed marine influence and varying degrees of water-rock interaction. Other diagenetic facies that occurred predominantly within the Pepper Formation exhibit dense recrystallized calcite seams identified as calcite beef, and cone-in-cone structures. Crystalline structures within these digenetic facies exhibit cone-in-cone and fibrous form where clays and organic matter occur adjacent to seams and at rims of calcite blades. Clay positioning could indicate clay was mobile during recrystallization. Stable isotopes for calcite beef and cone-in-cone structures range from δ¹³ C of (-3 to 1 ‰) and δ¹⁸ O of (-4.40 to -3.35 ‰). These values indicate a different diagenetic history from pervasive recrystallized forms. The cone-in-cone and calcite beef diagenetic fabrics may have formed through a physical diagenetic process occurring either during early or late diagenesis including displacive recrystallization, or crack-seal/ parallel expansion seams.

▼ The Eagle and Eagle East intrusions, located about 40 kilometers northwest of Marquette, MI, are two small, partially exposed, sub-vertical, funnel-shaped mafic/ultramafic intrusions emplaced in Paleoproterozoic black slates. Both intrusions host economic Ni-Cu-(PGE) sulfide deposits, the Eagle intrusion in its main body and the Eagle East intrusion in its feeder at depth. The Eagle deposit has been being mined by the Lundin Mining Corporation since 2014, which is now also expanding its operation to mine the Eagle East deposit. Transmitted light petrography, scanning electron microscopy, and electron microprobe analyses were performed on samples from six drill cores in the Eagle system, three from Eagle and three from Eagle East. Lundin additionally provided whole-rock geochemistry for five of these cores at ~1.5m intervals. The concentration of Ni in olivines in the Eagle and Eagle East intrusions were measured by electron microprobe. A bimodal distribution of Ni concentration in olivine - i.e., both enriched and unenriched populations being present - may have been evidence for multiple magma pulses in the Eagle system. However, olivine in both intrusions were determined to be universally Ni-enriched, which means that this line of inquiry was not useful for determining the number of magma pulses. The cumulate nature of samples were determined by whole-rock geochemistry, wherein incompatible trace elements including Zr, and La were used as proxies for the amount of intercumulus material present in a sample, as well as by visual estimation using transmitted-light petrography. Counter to the conclusions of Ding et el. (2010), variations in incompatible trace element ratios in various rock types in the Eagle system were satisfactorily explained by the cumulate nature and high sulfide content of the samples, with no need to invoke multiple parental magmas in the explanation. The intrusive breccia (or “IBRX”) lithology present in both the Eagle and Eagle East intrusions was studied with transmitted light petrography. It was determined to occur in at least two variations. Both variations have a feldspathic lherzolite matrix with subangular clasts, but in one type heavy sulfide mineralization (up to 30% by volume) occurs in the clasts and in the other type the clasts are nearly devoid of sulfides. In both cases the clasts have high pyroxene abundances and are devoid of olivine, but clasts with high sulfide content tend to have more plagioclase and are more heavily altered. In the Eagle East intrusion, sampled clasts were only of the low-sulfide variety. The IBRX clasts may be a slower-cooling version of the PRX lithology also present in the Eagle system. Alternatively, they may be part of an older intrusion that the Eagle system parental magma cannibalized at depth during emplacement. The main body of the Eagle East intrusion was studied by petrographic examination of a core that profiled its depth. While there was no significant change in cumulate rock type, the core did show modest cryptic variation with depth.…

▼ Golden eagles (Aquila chrysaetoes) are an iconic wide-ranging predator distributed across the Northern Hemisphere. In western North America, populations are considered to be stable, though there is a mounting concern that an anticipated increase in renewable wind energy development will threaten populations. Wind turbines are a known source of mortality for many avian species including golden eagles, thus there is a pressing need to offer land managers conservation planning guidance in light of future development. Working with several collaborators, I aimed to develop applied research in support of golden eagle conservation, while thoroughly testing the analytical rigor of methods we employed to address such questions. In chapter 1, I developed a stochastic population model for golden eagles with coauthors Zack Bowen, Brad Fedy, and Barry Noon. We sought to develop a model that faithfully captured the population dynamics of a non-migratory golden eagle population in western North America, while accounting for the demographic and environmental (process) variation inherent in vital rates. Using data from multiple long-term studies, we parameterized a stage-based matrix projection model and evaluated the contribution of vital rates to asymptotic population growth rates within a life-stage simulation analysis (LSA) framework. With a life history that is characterized by long-lived individuals with relatively low reproductive output, breeding adult survival dominates population dynamics for golden eagles. Thus it is unfortunate that breeding adult survival is the least-represented vital rate estimated in published literature. Simulating reduced survival across stage-classes revealed that a relatively minor (4%) reduction in survival resulted in a growing population to decline. Furthermore, targeting management at bolstering reproductive output is unlikely to compensate for reduced survival. Productivity rates (young fledged per pair) necessary to produce stable asymptotic growth rates (λ=1), when survival is reduced below 4% often falls above the range observed in field studies. Our findings combine to suggest that mitigating for eagle "take" (mortalities) due to anthropogenic sources including wind development should focus disproportionately on strategies that improve survival among breeding adults. Chapter 2 provides a spatially explicit framework for conservation planning and mitigation for golden eagles with respect to wind development. Co-advisor Brad Fedy and I fit resource selection functions (RSF) to golden eagle nest site data across two major ecoregions across Wyoming. Terrain indices, spatial surrogates for prey density, and landcover explained variation in nest-site locations compared to the available landscape. Overlaying predictive models of golden eagle nesting habitat with wind energy resource maps allowed us to highlight areas of potential conflict among eagle nesting habitat and wind development. Our results suggest that wind potential and the relative probability of golden eagle… Advisors/Committee Members: Noon, Barry (advisor), Fedy, Brad (advisor), Bailey, Larissa (committee member), Boone, Randall (committee member), Bowen, Zachary (committee member).

▼ Over the last decade, unconventional hydrocarbon resources have led the United States to a spot atop the list of largest oil producers in the world. During this time, major improvements in both technology and the general knowledge of shale reservoirs have driven down production costs while improving oil and gas recovery rates. The Reservoir Characterization Project (RCP) Phase XVII work seeks to further these advancements through a study of the value of time-lapse datasets and advanced reservoir characterization methods in the Eagle Ford Shale of South Texas, one of the most prolific unconventional plays in the world. RCP's project involves the analysis of various geophysical, geological, and engineering datasets sampling an approximately 50-square-mile study area of the Eagle Ford play. The available geophysical data includes time-lapse, multicomponent seismic data and vertical seismic profiles, along with microseismic event monitoring during hydraulic fracturing. The work presented in this thesis seeks to study the value of the nine-component surface seismic data for seismic amplitude variation with offset/angle (AVO/AVA) inversion and reservoir characterization. The vast majority of seismic datasets utilized in the oil and gas industry are single-component P-wave (PP) surveys. Nine-component surveys, which include converted wave (PS) data and pure-shear (SS) data, are rarely acquired due to the added costs and complexity of acquisition, processing, and interpretation. However, a better understanding of the additional information available in these datasets could be useful for determining whether or not these acquisitions are worthwhile. My analysis begins with their theoretical value for seismic inversion, which aims to recover P-impedance, S-impedance, and density models from recorded seismic amplitudes. Based on linearized approximations of the Zoeppritz equations, which describe the AVA of each data type, I determine that the PP data alone can provide accurate estimates of P-impedance; however, S-impedance and density are poorly constrained. The AVA equations suggest that PS data should improve estimates of S-impedance, but that SS data are likely necessary to obtain the critically important density term. These hypotheses are tested and confirmed through inversions of synthetic seismograms modeled from well log values, but with varying elastic parameters within the reservoir. The synthetic data are also used for comparison and quality control of the field data. After conditioning the field data, most notably through the removal of unrealistic lateral amplitude variations, four inversion methods are applied using a commercial software package: poststack PP, poststack SS (TT component), prestack PP, and joint prestack PP-PS. Inversion parameters are extensively tested to optimize results, and their effects are discussed along with some of the potential drawbacks of the methods applied. Comparing the inversion outputs shows that the joint inversion method produces the best results to utilize for further analysis… Advisors/Committee Members: Simmons, James (advisor), Shragge, Jeffrey (committee member), Tura, Ali (committee member), Prasad, Manika (committee member).
