Three-Dimensional Modeling Of Pennsylvanian Sandstone Units In The Mature Dudley Oil Field, Illinois, Usa, Jordan M. Martin, David H. Malone Dec 2016

Three-Dimensional Modeling Of Pennsylvanian Sandstone Units In The Mature Dudley Oil Field, Illinois, Usa, Jordan M. Martin, David H. Malone

Faculty Publications-- Geography, Geology, and the Environment

The purpose of this research is to better understand the Dudley Pool, a small, mature oil field in the Illinois Basin, USA by incorporating old geologic and geophysical data into modern petrophysical modeling software. The research focused on three-dimensional subsurface modeling of stratigraphy, structure, and porosity, to establish a more thorough understanding of oil occurrence at the Dudley Pool. This research also discusses the efficacy of three-dimensional modeling as an effective tool for evaluating, and potentially modifying, production efforts in mature petroleum fields with limited and/or poor-quality data. The modeling and calculations were completed using Petrel. Well information from all …


Evaluating Lithology As An Erosional Control On A Fluviokarst System In Northeastern Kentucky, Andrew K. Francis Dec 2016

Evaluating Lithology As An Erosional Control On A Fluviokarst System In Northeastern Kentucky, Andrew K. Francis

Theses and Dissertations

Longitudinal stream profiles can be used to evaluate landscape evolution. Lithology as a control on a stream profile is especially of interests because fluviokarst systems are characterized by the contact of carbonate and non-carbonate rocks at the surface. Due to the difference in weathering processes between carbonates and non-carbonate rocks, it is likely that there is a difference in their rates of erosion. Cave Branch and its tributary Horn Hollow, are fluviokarst systems located in northeastern Kentucky. This area is primarily comprised of sandstone and limestone. The objectives of this study were to determine if variation in lithology was creating …


Simulation Of Value Stream Mapping And Discrete Optimization Of Energy Consumption In Modular Construction, Md Mukul Chowdhury Nov 2016

Simulation Of Value Stream Mapping And Discrete Optimization Of Energy Consumption In Modular Construction, Md Mukul Chowdhury

Theses and Dissertations

With the increased practice of modularization and prefabrication, the construction industry gained the benefits of quality management, improved completion time, reduced site disruption and vehicular traffic, and improved overall safety and security. Whereas industrialized construction methods, such as modular and manufactured buildings, have evolved over decades, core techniques used in prefabrication plants vary only slightly from those employed in traditional site-built construction. With a focus on energy and cost efficient modular construction, this research presents the development of a simulation, measurement and optimization system for energy consumption in the manufacturing process of modular construction. The system is based on Lean …


Women On The Board Of Directors And Their Impact On The Financial Performance Of A Firm: An Empirical Investigation Of Female Directors In The United States Technology Sector, Obinna Mogbogu Oct 2016

Women On The Board Of Directors And Their Impact On The Financial Performance Of A Firm: An Empirical Investigation Of Female Directors In The United States Technology Sector, Obinna Mogbogu

Theses and Dissertations

This study uses a sample of S&P 500 firms in the United States technology sector to investigate the likely relationship between female directors and financial performance of firms measured by return on average assets and return on average equity as the two accounting based measures of performance. Reasonable theoretical arguments drawn from resource dependency, human capital, agency, and social psychology theory, suggests that the gender diversity of the board of directors may have either a positive, negative, or neutral effect on the financial performance of the firm. Using nonparametric statistics approach, we find a small negative relationship between female directors …
