The Marcellus and Utica shale plays continue to lead the way in an ever-expanding shale revolution with average daily production, growing from about 3 billion cubic feet (BCF) in 2010 to more than 24 BCF today. Forecasts suggest that this could grow to as much as 40 BCF in the next 5 years. Fortunately, sweet spots in the Utica in eastern Ohio and in the Marcellus in northern West Virginia and southwestern Pennsylvania are areas of wet gas production, downdip from oil production and updip from dry gas. Production in these regions represents about 40 percent of the total from …

From Creativity To Classification: A Logical Approach To Patent Searching, Marian G. Armour-Gemmen

Faculty & Staff Scholarship

Engineering students and professors need to understand and search intellectual property. In the past, librarians have instructed them on using the United States Patent Classification (USPC). In 2015, after a period of transition, the United States Patent and Trademark Office phased out the USPC and began exclusively classifying in the Cooperative Patent Classification (CPC). This adoption presented librarians a challenge of instructing students and professors in the easiest and most effective patent search. By tying patent searching to an example and presenting classification in an understandable fashion using CPC in conjunction with USPC, this writer presents a logical directed search …

Investigation Of Rope Formation In Gas–Solid Flows Through A 90° Pipe Bend Using High-Speed Video And Cfd Simulations, Sai S. Guda, Steven L. Rowan, Tao Yang

Faculty & Staff Scholarship

A study of rope formation in gas–solid flows through abrupt turns has been conducted. Experiments in which high-speed video was recorded and analyzed for solid concentration profiles were compared to CFD simulations utilizing both RANS and large eddy simulation turbulence models. In both simulations and experiments, particle-laden flows of air and ground flaxseed, with solid loadings of 35, 42, and 51% were considered. The results of the study demonstrate that both RANS and large eddy simulation can accurately predict particle roping. Furthermore, simulations show that the roping phenomenon is strongly dependent upon selection of an appropriate value for the coefficient …

Influential Women In Flight - Introduction, Becca Stegmann

Women in STEM

For this assignment, I created a collection of trading cards that provide biographies and important information about influential minority women in flight. The front of each card has basic demographic information, including each person’s name, birth date, hometown, and what they are known for. The back of each card has a slightly longer explanation of each person, followed by something they are quoted with saying and some key facts about their lives. The cards can be printed out in color and laminated for longevity if desired.

A Tabu Search Heuristic For A Generalized Quadratic Assignment Problem, Alan Mckendall, Chihui Li

Faculty & Staff Scholarship

The generalized quadratic assignment problem (GQAP) is the task of assigning a set of facilities to a set of locations such that the sum of the assignment and transportation costs is minimized. The facilities may have different space requirements, and the locations may have varying space capacities. Also, multiple facilities may be assigned to each location such that space capacity is not exceeded. In this paper, an application of the GQAP is presented for assigning a set of machines to a set of locations on the plant floor. Construction algorithms and a simple tabu search heuristic are developed for the …

The Effect Of The 2015 Earthquake On The Bacterial Community Compositions In Water In Nepal, Sital Uprety, Pei-Ying Hong, Nora Sadik, Bipin Dangol, Rameswor Adhikari, Antarpreet Jutla, Joanna L. Shisler, Patrick Degnan, Thanh H. Nguyen

Faculty & Staff Scholarship

We conducted a study to examine the effect of seasonal variations and the disruptive effects of the 2015 Nepal earthquake on microbial communities associated with drinking water sources. We first characterized the microbial communities of water samples in two Nepali regions (Kathmandu and Jhapa) to understand the stability of microbial communities in water samples collected in 2014. We analyzed additional water samples from the same sources collected from May to August 2015, allowing the comparison of samples from dry-to-dry season and from dry-to-monsoon seasons. Emphasis was placed on microbes responsible for maintaining the geobiochemical characteristics of water (e.g., ammonia-oxidizing and …

Space Race - Introduction, Jesse Lackey

Cold War & Space Race

The infographic linked below is a timeline of events in 20^th-century America related to the Cold War, the Space Race, and the Civil Rights Movement. The timeline is designed to put the events in Hidden Figures into historical context. The timeline chronologically compares groundbreaking historical events such as the Civil Rights Act of 1964 and the creation of NASA alongside the historical presence of the three women, Dorothy Vaughan, Katherine Johnson, and Mary Jackson, that the reading is focused around. The book hops around from year to year and is very difficult to follow chronologically. That is part …

Emerging New Types Of Absorbents For Postcombustion Carbon Capture, Quan Zhuang, Bruce Clements, Bingyun Li

Faculty & Staff Scholarship

Carbon capture is the most probable technology in combating anthropogenic increase of CO2 in the atmosphere. Works on developing emerging absorbents for improving carbon capture performance and reducing process energy consumption are actively going on. The most worked‐on emerging absorbents, including liquid‐liquid biphasic, liquid‐solid biphasic, enzymatic, and encapsulated absorbents, already show encouraging results in improved energy efficiency, enhanced CO2 absorption kinetics, increased cyclic CO2 loading, or reduced regeneration temperature. In this chapter, the latest research and development progress of these emerging absorbents are reviewed along with the future directions in moving these technologies to higher‐technology readiness levels.

Analysis Of The Production Data From Marcellus Shale Wells, Amanda Parrish

Graduate Theses, Dissertations, and Problem Reports

The increasingly prevalent practice of unconventional technologies has called for the need for the critical analysis of production decline rates to meet economic targets. The high early time production returns and transient flow make matching a production curve to known methods of decline curve analysis problematic.

This research focuses on finding a technique that best fits a known production curve and then applying that technique to another well to check its accuracy. The goal is to find the earliest time of production data necessary to predict an accurate production curve over the lifespan of the well. This is essential to …

Dynamic Model And Estimator Development For A Smart Refractory Brick With Embedded Wireless Sensors For Gasifier Applications, Qiao Huang

Graduate Theses, Dissertations, and Problem Reports

The operating temperature is one of the most important variables for gasifier operation. A higher temperature can shorten the service life of the refractory lining. A lower temperature can reduce the extent of carbon conversion and disrupt the flow of molten slag in a slagging gasifier. Therefore temperature is one of the most important variable in a gasifier. In slagging gasifiers, molten slag can penetrate into the refractory lining leading to refractory spallation, undesired downtime, and costly replacement. Even though the temperature and extent of slag penetration are extremely important for the gasifier operation, they cannot be measured reliably by …
