Measurement Of Hysteretic Shale Capillary Pressure – Saturation Relationships Using A Water Activity Meter, Brendan Michael Donnelly

Masters Theses

Capillary pressure is the pressure difference across the interface of two immiscible fluids within a porous medium due to the interfacial tension between fluids and is related to both the properties of the fluids and the porous medium. Capillary pressure within a porous medium will change depending upon its degree of saturation. Understanding the relationship between capillary pressure and saturation for a rock allows for the modeling of multi-phase flow. Many traditional methods of measuring capillary pressure are unsuitable for the characterization of shale due to their inability to measure the high capillary pressures found within the small pores. Furthermore, …

Lithologic Properties Of The Upper Ordovician Utica Formation, Michigan Basin, Usa: A Geological Characterization And Assessment Of Carbon Dioxide Confinement Potential, Frank Richard Sattler

Masters Theses

The Utica/Maquoketa Shale is considered to be the primary confining layer for Cambro-Ordovician CO₂ sequestration targets in the Midwest in the Michigan and Illinois basins, respectively. Prospective regional geologic seals in mudrock formations possess a combination of lithologic properties including nanometer scale pore space, elevated breakthrough pressures for non-wetting fluid phases and ductile mechanical deformation. Mineralogical composition is related to and typically controls these properties.

The objective of this study is to investigate the geological controls on stratigraphic and lithologic variability in the Utica/Collingwood in the Michigan basin. Twelve conventional cores and hundreds of modern well logs from the …

3d Seismic Data Interpretation Of Boonsville Field, Texas, Aamer Ali Alhakeem

Masters Theses

"The Boonsville field is one of the largest gas fields in the US located in the Fort Worth Basin, north central Texas. The highest potential reservoirs reside in the Bend Conglomerate deposited during the Pennsylvanian. The Boonsville data set is prepared by the Bureau of Economic Geology at the University of Texas, Austin, as part of the secondary gas recovery program. The Boonsville field seismic data set covers an area of 5.5 mi². It includes 38 wells data. The Bend Conglomerate is deposited in fluvio-deltaic transaction. It is subdivided into many genetic sequences which include depositions of sandy conglomerate representing …
