Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Lost circulation and problems related to drilling present a major challenge for the drilling industry. Each year, billions are spent to treat these problems. There is not a single solution to lost circulation because of the complexity and kind of formations susceptible to this issue. Lost circulation treatment data for the Shuaiba formation (induced fractured formation) were gathered from drilled wells in Southern Iraq (over 2000). Treatments have been grouped according to the volume of mud loss as complete, severe, and partial loss remedies. Detailed costs and probabilities calculations were conducted. The costs of three types of loss treatments (partial, …

Impact Of Rheology Models On Horizontal Well Polymer Flooding In A Heavy Oil Reservoir On Alaska North Slope: A Simulation Study, Jianqiao Leng, Mingzhen Wei, Baojun Bai, Randall S. Seright, Yin Zhang, David Cercone, Samson Ning

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Polymer rheology can have either a positive or a negative effect on polymer flooding performance under varied circumstances. Many researchers have studied the effect of polymer rheology in a vertical well, but no field scale studies have been conducted to investigate whether polymer rheology is beneficial to polymer flooding in heavy oil reservoirs developed by horizontal wells. In this paper, we conducted a numerical simulation study to examine the effect of HPAM polymer rheology on a polymer flooding pilot, which is the first-ever project conducted on a heavy oil reservoir from Alaska North Slope (ANS) developed by horizontal wells. Three …

Assessment Of Empirical And Semi-Analytical Algorithms Using Modis-Aqua For Representing In-Situ Chromophoric Dissolved Organic Matter (Cdom) In The Bering, Chukchi, And Western Beaufort Seas Of The Pacific Arctic Region, Melishia I. Santiago, Karen E. Frey

Geography

We analyzed a variety of satellite-based ocean color products derived using MODIS-Aqua to investigate the most accurate empirical and semi-analytical algorithms for representing in-situ chromophoric dissolved organic matter (CDOM) across a large latitudinal transect in the Bering, Chukchi, and western Beaufort Seas of the Pacific Arctic region. In particular, we compared the performance of empirical (CDOM index) and several semi-analytical algorithms (quasi-analytical algorithm (QAA), Carder, Garver-Siegel-Maritorena (GSM), and GSM-A) with field measurements of CDOM absorption (aCDOM) at 412 nanometers (nm) and 443 nm. These algorithms were compared with in-situ CDOM measurements collected on cruises during July 2011, 2013, 2014, 2015, …

Distributional Arguments, In Reverse, Alex Raskolnikov

Faculty Scholarship

This Article contends that the government should consider – rather than ignore – distributional consequences both in the design of legal rules and during legal transitions. This does not mean that the distributional effect of every legal rule should be measured and taken into account in the rule’s design. But if the likely distributional effects are unintended, large, and objectionable, if the efficiency of the legal rule is doubtful, if the compensating tax-and-transfer adjustment is not forthcoming (or has not occurred), policymakers should take distribution into account. One way of doing so is to choose among several alternative legal rules …

Joint Co2 Mole Fraction And Flux Analysis Confirms Missing Processes In Casa Terrestrial Carbon Uptake Over North America, Sha Feng, Thomas Lauvaux, Christopher A. Williams, Kenneth J. Davis, Yu Zhou, Ian Baker, Zachary R. Barkley, Daniel Wesloh

Geography

Terrestrial biosphere models (TBMs) play a key role in the detection and attribution of carbon cycle processes at local to global scales and in projections of the coupled carbon-climate system. TBM evaluation commonly involves direct comparison to eddy-covariance flux measurements. We use atmospheric CO2 mole fraction ([CO2]) measured in situ from aircraft and tower, in addition to flux-measurements from summer 2016 to evaluate the Carnegie-Ames-Stanford-Approach (CASA) TBM. WRF-Chem is used to simulate [CO2] using biogenic CO2 fluxes from a CASA parameter-based ensemble and CarbonTracker version 2017 (CT2017) in addition to transport and CO2 boundary condition ensembles. The resulting “super ensemble” …

An Investigation Of Unsteady Thermal Exchange Processes In Geothermal Heat Exchangers, Ganesh Ravi Shanker

Doctoral Dissertations

“Geothermal heat exchangers, has become one of the highly recognized non conventional heat exchangers as they utilize renewable energy source earth to initiate the thermal energy transfer. However, these heat exchangers suffer from a expensive installation cost due to their conservative design model, thereby facilitating the need to identify and improve the design. In this dissertation, three gaps, which identifies improvement over conservative design were investigated, to assess the heat exchanger performance. In the first approach, borehole thermal and geometrical properties were investigated keeping the outlet leg of the heat exchanger as adiabatic, which neglects the thermal short-circuiting between the …

Adaptive Dynamic Programming Methods For Tracking Current Control Of Switched Reluctance Motor Drive, Hamad Alharkan

Doctoral Dissertations

“This research investigates the application of adaptive dynamic programming (ADP) methods for the current control of switched reluctance motors (SRM). Since the traditional current controllers have large current ripples that increase torque ripples and acoustic noise, optimal tracking controllers using reinforcement learning (RL) approaches are introduced as an alternative adaptive technique for SRM drives. The proposed optimal tracking controllers can minimize current ripples and cope with uncertainties within the inductance profile of the SRM. The work is composed of three papers. In the first paper, a novel Q-learning scheduling method for the current controller of a switched reluctance motor (SRM) …

Political Systems And Revolution: The Cases Of Egypt And Tunisia, Ibrahim S.I Rabaia

Student Works (2020-2029)

Revolution in MENA is a long-term process needing a long time to correct the structural failures of the existing political systems. In other words, revolutions were created to change the status quo, pave the way to a breakthrough in the political system, and open the political sphere by introducing a more inclusive and dynamic process for entering these systems. The mismatch between inputs and outcomes in the Egyptian and Tunisian political systems produced failures in dealing with the political, economic, and social demands of the revolutionary powers in both countries. Such a failure increased the chances of success for the …

Harry Potter And The Gluttonous Machine, Jason A. Beckett

Faculty Journal Articles

In this paper, I outline the colonial structure of international law, and examine the short decline or suppression of its coloniality in the so-called ‘era of decolonisation’, then illustrate its resurgence in the modern neo-colonial order. PIL has split into two separate systems. One includes, and is justified by, the heroic tales of human rights and ‘Humanity’s Law’. The other is the actualised system of International Economic Law (IEL), an order driven by the need of the over-developed states to plunder the under-developed states’ resources and labour, to subsidise the luxury to which we have grown accustomed. One purports to …

Frequency-Selective Metasurface Integrated Uncooled Microbolometers, Mahmoud Almasri, Edward C. Kinzel

Patents

A metasurface integrated microbolometer having a sensing layer (e.g., SixGeyOI-x-y ). The presence of the metasurface provides selectivity with respect to wavelength, polarization and angle-of-incidence. The presence of the metasurface into the microbolometer affects conversion of electromagnetic to thermal energy, thermal response, electrical integration of the micro bolometer, and the tradeoff between resistivity and temperature coefficient of resistance, thereby allowing the ability to obtain a sensing with high temperature coefficient of resistance with lower resistivity values than that of films without the metasurface. The presence of the metasurface removes the need for a Fabry-Perot cavity.

Characterizations Of Student, Instructor, And Textbook Discourse Related To Basis And Change Of Basis In Quantum Mechanics, Kaitlyn Stephens Serbin, Megan Wawro, Rebecah Storms

School of Mathematical & Statistical Sciences Faculty Publications

Communities develop social languages in which utterances take on culturally specific situated meanings. As physics students interact in their classroom, they can learn the broader physics community’s social language by co-constructing meanings with their instructors. We provide an exposition of a systematic and productive use of idiosyncratic, socially acquired language in two classroom communities that we consider to be subcultures of the broader community of physicists. We perform a discourse analysis on twelve quantum mechanics students, two instructors, and the course text related to statements about basis and change of basis within a spin-½ probability problem. We classify the utterances’ …

Being Needed, Cared For, And Present: Belonging And Disability In The Seventh-Day Adventist Church In North America, Shannon M. Trecartin, Mikelle Wile, Terrance P. Trecartin, Petr Činčala

Faculty Publications

Many Christian churches seek to be places of belonging, yet present barriers to inclusion. The present research focuses on disability and belonging in members of the Seventh-day Adventist (SDA) Church in North America. Data from the SDA Global Church Survey (2017–2018) were used to measure attendance, perceived care, and sense of being needed. Results: Differences in attendance, leadership, and “feeling cared for” were observed. The findings of this study suggest that the SDA Church has had both successes and room for growth in terms of creating opportunities for belonging among people with disabilities. Implications for other denominations are also discussed.

Christian Dignity And The Overlapping Consensus, Frederick Mark Gedicks

Faculty Scholarship

This Article rejects arguments by Christian leaders, scholars, and others who lament the secularization of the West and urge Christian dignity as the foundation of universal human rights. It argues instead that only a secular conception of dignity free of Christian metaphysics can create an overlapping consensus in support of human rights.

Part I describes the roots of Christian dignity in medieval theology and status. Part II briefly recounts how the Renaissance and Enlightenment re-centered the end of dignity from knowing God to knowing oneself, while the Reformation’s extension of original sin to the intellect left Catholicism as the primary …
