A variety of oil recovery improvement techniques has been developed and applied to the productive life of an oil reservoir. Reservoir simulators have a definitely established role in helping to identify the opportunity and select the most suitable techniques to optimum improvement in reservoir productivity. This is significantly important for those reservoirs whose operating and development costs are relatively expensive, because numerical modeling helps simulate the increased oil productivity process and evaluates the performance without undertaking trials in field. Moreover, rapid development in modeling provides engineers diverse choices. Hence the need for complete and comprehensive case studies is increasing. This study will show the different characteristics of in-house (UTCOMP and GPAS) and commercial simulators and also can validate implementation and development of models in the future. The purpose of this thesis is to present a series of case studies with analytical solutions, in addition to a series of more complicated field cases studies with no exact solution, to verify and test the functionality and efficiency of various simulators. These case studies are performed with three reservoir simulators, including UTCOMP, GPAS, and CMG. UTCOMP and GPAS were both developed at the Center for Petroleum and Geosystem Engineering at The University of Texas at Austin and CMG is a commercial reservoir simulator developed by Computer Modelling Group Ltd. These simulators are first applied to twenty case studies with exact solutions. The simulation results are compared with exact solutions to examine the mathematical formulations and ensure the correctness of program coding. Then, ten more complicated field-scale case studies are performed. These case studies vary in difficulty and complexity, often featuring heterogeneity, larger number of components and wells, and very fine gridblocks. / text

To understand what makes organizations alike, neo-institutional scholars explore institutional demands and argue that organizations become isomorphic because specific legitimacy demands in their institutional environments require organizations to comply with given rules and norms. But, what if the institutional demands in the given environment conflict with one another? In response to this question, extant literature recognizes the existence of conflicting institutional demands and studies organizational responses to such demands. However, prior studies on conflicting demands tend to explore organizations with a single identity in a specific field. In extension, this study pays attention to organizations that possess conflicting identities across different sectors. Applying an ethnographic approach, this study takes an in-depth look at government-run non-governmental organization (GONGO) and addresses three research questions: first, how does an organization with conflicting identities come into being? Second, what conflicting demands does such organization encounter? Third, how does such an organization respond to those demands? This study collects data through three months of fieldwork in two GONGOs located in Beijing and Guiyang. The findings illustrate three types of institutional contexts where conflicting demands can arise. This classification is based on two variables, which are the complexity of an organization’s identities, and the multiplicity of fields where dominant actors occur. The S-S, M-S and M-M types are therefore identified in this framework. Beyond this, the nature and features of conflicting demands faced by GONGOs are also explored in these types. Additionally, this study introduces inter-organizational power dynamics between dominant actors into its analysis of organizational responses. Given the inter-organizational politics, GONGOs develop four strategies to cope with conflicting demands. These strategies include dilatoriness, negotiation, replacement, and exploitation. The conditions under which particular strategy is more likely to be adopted are also discussed. In sum, this study hopes to shed light on conflicting institutional demands encountered by organizations with conflicting identities and draw attention to inter-organizational politics in institutional environments. Empirically, this study hopes to better understand the special organization creature—GONGOs—and its implications on globalization in China. / published_or_final_version / Sociology / Master / Master of Philosophy

This report will review some of the current and past literature on case-based learning and instruction, while also providing the reader with a background on the development of this particular learning strategy with implications for future research. The first two chapters will review case-based learning/instruction by examining its background and history, current uses, and benefits associated with its current uses in educational settings, as well as how these benefits may apply to younger learners. In chapter three, I have discussed some of the more well established discussion-based methods in K-12 education, specifically those most similar to case-based learning. This section is followed by suggestions for implementing case-based learning and instruction with younger learners. The report concludes with limitations associated with case-based learning and its implementation with younger learners. / text
