Variations In Produced Water Chemistry And Relation To Regional Geology And Production In The Marcellus Shale, Northcentral West Virginia, Jonathan M. Brady
Variations In Produced Water Chemistry And Relation To Regional Geology And Production In The Marcellus Shale, Northcentral West Virginia, Jonathan M. Brady
Graduate Theses, Dissertations, and Problem Reports
An investigation of 74 Marcellus Shale wells across northcentral West Virginia indicates changes in produced water chemistry and quantity can be related to geologic conditions based on well logs and core data. These changes are determined by reviewing multiple produced water analyses for individual wells for periods up to ten years. Results show variations among the areas in this study. From west to east across central Harrison County to central Taylor County, then north into Monongalia County, gamma-ray logs show increasing intensity, especially in the middle and lower Marcellus. XRD mineralogy from core data shows increasing clay content from west …
Physical And Chemical Properties Of Clastic Sediments From Two Caves In The Northern Karst Region Of Puerto Rico, Autum R. Downey
Physical And Chemical Properties Of Clastic Sediments From Two Caves In The Northern Karst Region Of Puerto Rico, Autum R. Downey
Graduate Theses, Dissertations, and Problem Reports
Geochemical properties and organic characteristics are essential to understanding the general depositional dynamics of a cave. Most work on clastic cave sediments focuses on physical properties of sediments. Little work has been done on bulk organic matter and geochemical properties.
This project reports physical and geochemical characterization of cave sediments from two caves in the northern karst region of Puerto Rico: El Tallonal Cave and Cueva Clara. Core and grab samples were collected and analyzed for particle size, total organic carbon, total nitrogen, organic matter characteristics using fluorescence spectroscopy, and major and minor elements using X-ray fluorescence (XRF). The sediments …
Qualitative And Quantitative Analysis Of Carbonate Waters In The Peters Mountain Region Of Monroe County, Wv, Emily A. Bausher
Qualitative And Quantitative Analysis Of Carbonate Waters In The Peters Mountain Region Of Monroe County, Wv, Emily A. Bausher
Graduate Theses, Dissertations, and Problem Reports
Water in Monroe County, WV is used extensively for public and private supply and requires quantification, chemical analysis, and assessment for contamination susceptibility. Over 250 springs were previously identified in the eastern side of Monroe County on or near Peters Mountain; 14 were continuously monitored in this study. Springs were grouped based on geologic and spatial distribution: interbedded clastic-rock springs on the mountain flanks, carbonate springs in the valley, and a thermal spring associated with the St. Clair thrust fault. Clastic and carbonate springs have calcium-magnesium-bicarbonate chemistries, neutral pHs and high alkalinities; the thermal spring has calcium-magnesium-sulfate-carbonate chemistry, low pH, …
