Reservoir Characterization And Static Earth Modeling For Potential Co2 Storage In Upper Pennsylvanian Cyclothems Of Midcontinent, Usa, Valerie Lynn Smith

Graduate Theses, Dissertations, and Problem Reports

This dissertation details the estimation of CO₂ storage volume using reservoir characterization and the building of static earth models in two papers: 1) for Sleepy Hollow Field in Red Willow County, Nebraska and, 2) for Huffstutter Field, Phillips County, Kansas. These models are used to obtain estimates of CO₂ storage capacity in stacked carbonate intervals of the Pennsylvanian Lansing and Kansas City groups (LKC). The LKC constitutes a regional succession of interbedded carbonates and shales. Located over the Cambridge Arch of Nebraska, these interbedded units were evaluated for carbon storage potential. Understanding the occurrence of carbonate porosity among …

Relating Recharge Mechanisms To Chemical Changes In An Updip Appalachian Coal Mine Discharge: A Case Study From Lambert Run, West Virginia, Matthew Lewis Bell

Graduate Theses, Dissertations, and Problem Reports

Impaired drainage from active and abandoned mines degrades the water quality of receiving streams and aquifers. Coal mine drainage (CMD) has been studied for decades in Appalachia, but unknowns and uncertainties are still present, including the influence of mine hydrogeology on the outflow chemistry of above-drainage mines. To evaluate the influence of recharge type on above-drainage mine chemistry, samples were collected every two weeks at a CMD outflow treatment system in Harrison County, West Virginia.

Samples were collected to measure geochemical changes taking place in the mine workings and along the flowpath of the passive treatment system. Samples were divided …
