A three-dimensional (3D) geologic model was developed for Quaternary deposits in
southern Walworth County, WI using Petrel, a software package primarily designed for use in
the energy industry. The purpose of this research was to better delineate and characterize theshallow glacial deposits, which include multiple shallow sand and gravel aquifers. The 3D modelof Walworth County was constructed using datasets such as the U.S. Geological Survey 30 mdigital elevation model (DEM) of land surface, published maps of the regional surficial geology andbedrock topography, and a database of water-well records. Using 3D visualization and interpretationtools, more than 1400 lithostratigraphic picks were …

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 …
Three-Dimensional Geologic Model Of The Pecatonica Gas Storage Field, Winnebago County, Illinois, Nicole Kron, David Malone, Eric Peterson

This study involves the construction of a three-dimensional (3D) geologic model of Paleozoic strata that are part of an underground gas storage field in northern, Illinois, USA. The Pecatonica Anticline trends 60W and plunges gently to the southeast. It is 10 km long and 3 km wide, and verges to the NE. Six water wells and 22 gas wells were used to create the 3-D geologic model in Petrel using well tops as determined from wire-line logs. The following horizons were created for the Cambrian and Ordovician strata: the Ancell, Trempealeau, Franconia, Ironton-Galesvilles, Eau Claire Proviso A and B, Eau …
