Reservoir Characteristics And Lateral Variability Of The Marcellus Formation At The Allegheny Mountain Front, Bruno J. Abersold
Reservoir Characteristics And Lateral Variability Of The Marcellus Formation At The Allegheny Mountain Front, Bruno J. Abersold
Graduate Theses, Dissertations, and Problem Reports
The Marcellus Formation, a large shale gas reservoir located within in the Appalachian basin, produces the energy that fuels the economy across the United States. Well data and rock core for the Coastal 1H well, found in Fayette County, Pennsylvania, provides the basis to understand reservoir characteristics and depositional processes of the Marcellus Formation across the basin. The well is located near along the eastern edge of the productive fairway and adjacent to the Allegheny mountain front. We used characteristics, such as total organic carbon (TOC), geomechanical properties, and lithology, to integrate with ten other available wells across the basin. …
Unconventional Gas Pipeline Right-Of-Way Influence On Wildlife, Samuel C. Knopka
Unconventional Gas Pipeline Right-Of-Way Influence On Wildlife, Samuel C. Knopka
Graduate Theses, Dissertations, and Problem Reports
The development of horizontal drilling for natural gas in the Marcellus Shale in 2004 resulted in rapid exploitation of the play in the Appalachian Basin. This “unconventional” gas well drilling accesses resources deeper beneath the surface and allows for multiple wells to be co-located on a single well pad. This results in fewer, but larger, well pads on the landscape than traditional vertical wells. Pipelines are required to transport the volumes of gas produced by unconventional wells to production facilities and market. The effects of gathering pipelines, which transport gas from well pads to larger transport pipelines, are poorly studied …
Natural Gas Conversion To Value-Added Chemicals By Microwave Catalytic Processes, Brandon Robinson
Natural Gas Conversion To Value-Added Chemicals By Microwave Catalytic Processes, Brandon Robinson
Graduate Theses, Dissertations, and Problem Reports
Ethane is the second-largest component in natural gas and is typically separated out to minimize condensation in the pipelines. The technical difficulties and cost associated with the transportation and the storage of ethane have led companies to start burning natural gas to produce power or flaring which attributes to the global CO2 emission problem. The conversion of ethane to higher-value liquid products is of increasing importance so that the natural gas can be safely utilized and cost-effectively transported. Existing commercial technologies used to convert ethane to liquid chemical products are typically based on the indirect syngas route, such as …
On The Improvement Of The Indirect Quantification Of Methane Emissions: A Stationary Single Sensor Approach, Robert Scott Heltzel
On The Improvement Of The Indirect Quantification Of Methane Emissions: A Stationary Single Sensor Approach, Robert Scott Heltzel
Graduate Theses, Dissertations, and Problem Reports
There is a need for improved indirect quantification of methane emissions, particularly from the natural gas industry. Natural gas production continues to increase along with the number of wells and production sites. These production sites have the potential to contribute significant levels of methane emissions. Methane is a potent greenhouse gas and the primary component of natural gas. A more complete understanding of emissions through improved quantification will lead to enhanced mitigation. Emissions have historically been quantified with both direct and indirect methods, with varying results. Emissions have been shown to be both temporally and spatially variable. These facts have …
Quantifying The Impact Of Load-Following On Gas-Fired Power Plants, Yifan Wang
Quantifying The Impact Of Load-Following On Gas-Fired Power Plants, Yifan Wang
Graduate Theses, Dissertations, and Problem Reports
Due to rapid penetration of renewables into the grid, natural gas combined cycle (NGCC) power plants are being forced to cycle their loads more frequently and rapidly than for which they were designed. However, the impact of load-following operation on plant efficiency and equipment health are currently poorly understood. The objective of this work is to quantify the impact of load-following on the gas-fired plants by developing high-fidelity multi-scale dynamic models. There are four main tasks in this project. First, dynamic model of an NGCC power plant has been developed. The main components of the NGCC plants are the gas …
