Gas Production Forecasting Using Automatic Type Curve Matching, Walter Jonathan Diazgranados
Gas Production Forecasting Using Automatic Type Curve Matching, Walter Jonathan Diazgranados
Graduate Theses, Dissertations, and Problem Reports
As the demand for natural gas has increased in the last years, also the need for forecast reliable gas recoveries. Gas type curves are one of the methods utilized to estimate future well performance. The purpose of this study is the utilization of the Aminian et al type curves to model gas well performance. Unlike other studies developed in the past, Aminian et al type curves account for important factors ignored in the derivation of the proposed theoretical solutions. Thus, the pressure dependency of gas viscosity and compressibility, as well as the pressure loss owing to non-Darcy flow, make of …
Sedimentology Of Historic And Prehistoric Deposits In The Drainage Basin Of Deep River And Muddy Creek On The Piedmont Of North Carolina, Victoria Leanne Spurgeon
Sedimentology Of Historic And Prehistoric Deposits In The Drainage Basin Of Deep River And Muddy Creek On The Piedmont Of North Carolina, Victoria Leanne Spurgeon
Graduate Theses, Dissertations, and Problem Reports
Deep River and Muddy Creek flow across a granitic and volcanic terrain intruded by diabase dikes in the Piedmont physiographic province of central North Carolina. Geoarchaeological and sedimentological investigation of these Piedmont streams included fourteen trenches dug at four floodplain localities. Soils in these trenches were described using standard soil taxonomy and sampled for particle-size, magnetic susceptibility, and mineralogical analyses.;Increased upland erosion rates, after European settlement, left more than a meter of historic sediments in some areas of the floodplains. A paleosol, indicated by an Ab horizon, records the floodplain surface at the time of European contact. This paleosol, dated …
Magnetic Model Studies Of The New York--Alabama Lineament And Other Magnetic Anomalies In West Virginia, Tanner Anthony Sattler
Magnetic Model Studies Of The New York--Alabama Lineament And Other Magnetic Anomalies In West Virginia, Tanner Anthony Sattler
Graduate Theses, Dissertations, and Problem Reports
This study was undertaken to model magnetic anomalies observed in aeromagnetic data across the central Appalachian foreland of West Virginia. Total field intensity models of the New York Alabama magnetic lineament indicate that the maximum depth to the center of the source object could be approximately 20 kilometers and have dips anywhere between 32'NW to 27'SE. The models could not differentiate between suture zone (dipping) and transform zone (nearly vertical) origins.;Prominent alignments of residual highs and lows and magnetic anomaly terminations are present in the residual anomaly data. In the plateau, model studies show that disruptions of residual anomalies could …
Hydrogeologic Analysis Of Streamflow In Relation To Underground Mining In Northern West Virginia, David Robert Gill
Hydrogeologic Analysis Of Streamflow In Relation To Underground Mining In Northern West Virginia, David Robert Gill
Graduate Theses, Dissertations, and Problem Reports
Land subsidence, caused by longwall mining, has a negative effect on overlying watersheds. Nine streams were monitored from their headwaters to their mouths for discharge, temperature, conductivity, alluvium thickness, and alluvium sediment size. Seven streams are located over undermined longwall panels, with two located over non-undermined areas. Discharge data shows that non-undermined watersheds do not experience stream dewatering, regardless of alluvium thickness or sediment size. Streams located over active or recently mined longwall panels experience water loss that ranges from slight to total. Impacted streams with overall increases in conductivity and decreases in water temperature suggest that lost streamflow travels …
