LITHOSTRATIGRAPHIC AND PETROPHYSICAL ANALYSIS OF THE MIDDLE DEVONIAN MARCELLUS SHALE AT THE MAMONT PROSPECT, WESTMORELAND COUNTY, PENNSYLVANIA A Thesis Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Master of Science Hydrogeology By Ty M. Taylor December 2013 Accepted by: Dr. James W. Castle, Committee Chair Dr. Ronald Falta Dr. George M. Huddleston III ABSTRACT The organic-rich Middle Devonian Marcellus Shale of the Appalachian basin is a rapidly developing natural gas play. Stratigraphic boundaries of the Marcellus Shale in Westmoreland County, Pennsylvania were identified using geophysical logs from 10 vertical gas-producing wells in a 23 sq. km area. Gamma-ray, bulk density, and resistivity well logs were examined to assess hydrocarbon potential. Values of porosity, total organic carbon (TOC), and water saturation (SW) were derived and mapped by incorporating well-log data into Marcellus-specific formulas.
