Quaternary glacial till, outwash, lake sediments, and loess compose the surficial deposits of McHenry County, Illinois. Much of the landscape of McHenry County were formed by at least three separate advances of the Harvard Sublobe of the Wisconsin Episode Lake Michigan Lobe, which was part of the Laurentide Ice Sheet. This project focuses on the delineation of the stratigraphy and extent of the Pearl-Ashmore Aquifer. The Pearl-Ashmore Aquifer is the combination of the proglacial outwash of the Wisconsin Episode Ashmore Tongue of the Henry Formation and the youngest outwash associated with the Illinois Episode, which is the Pearl Formation. A …

Maximizing resource extraction from mature oilfields requires enhanced and secondary recovery techniques. The success of these methods relies on knowledge and understanding of the reservoir geology and hydraulics. At the Loudon Oilfield (Illinois, USA), enhanced oil recovery is being used to extend the production life of the reservoir. The suitability and placement of additional wells for oil recovery processes required three-dimensional (3D) facies and porosity modeling of the oilfield. The purpose of this work was to assess the ability of a porosity model to predict sandstone facies. The facies model for the Loudon field was generated using data obtained from …

Natural gas is stored underground in geologic structures throughout the United States. However, complexities associated with these geologic structures may provide vertical pathways for gas migration, and thus gas loss. Possible upward migration (loss) of natural gas in an underground gas storage field in stimulated this investigation that aims to identify potential migration pathways. Spatial analysis of volume of shale (Vsh) and formation porosity (n) values were conducted in conjunction with high-resolution shallow seismic surveys to identify potential vertical pathways. Surficial gas accumulations within glacial deposits were confirmed by the seismic surveys. These gas pockets accumulated by migration along steeply …
