Paleogeothermal Conditions in the Illinois Basin During Late Paleozoic Coalification
In the Illinois Basin (IB) the coals with the highest rank are not located within the deepest part (depocenter) of the basin, but rather occur to the south near to an intrusion, additionally the analysis of vitrinite reflectance in deep wells suggests that the paleogeotherm of the basin contain an …

Caprock characteristics and uncertainties in geological carbon sequestration in the Illinois basin
… for reducing greenhouse gas emissions to the atmosphere. Success of commercial-scale GCS requires containment of injected CO2 and the sealing ability of the overlying caprock has been identified as an important factor related to the long-term storage of CO2. Caprock research is recent and …

Illite in the Lower Paleozoic of the Illinois Basin: Origin, age, and polytype quantification
Illite was first named in 1937 in Illinois by Ralph Grim, one of the founders of clay mineralogy. Illite is the most abundant clay mineral on the earth's surface. However, we know very little about the origin of illite in Illinois. This dissertation focuses on two aspects of illite in the Lower …

Carbonate Microfacies and Depositional Environments of the Kinkaid Formation (Upper Mississippian) of the Illinois Basin
The carbonate rocks of the Kinkaid Formation (Upper Mississippian) of the Illinois Basin were sampled at an average vertical interval of 17 centimeters from twelve stratigraphic sections in Southern Illinois and Western Kentucky, to determine their environments of deposition. Thin sections wer

Geologic Factors Affecting Hydrocarbon Occurrence in Paleovalleys of the Mississippian-Pennsylvanian Unconformity in the Illinois Basin
<p>Paleovalleys associated with the Mississippian-Pennsylvanian unconformity have been identified as potential targets for hydrocarbon exploration in the Illinois Basin. Though there is little literature addressing the geologic factors controlling hydrocarbon accumulation in sub-Pennsylvanian …

Subsurface dolomitization and porosity occlusion within Early to Middle Ordovician strata of the Illinois Basin, USA
… and geochemical characteristics of samples from the Early Ordovician Shakopee Dolomite and Everton Formation, and the overlying Middle Ordovician St. Peter Sandstone, obtained from drill cores and outcrops in the Illinois Basin indicate that subsurface dolomitization locally reduced primary …

Mechanisms of dolomitization in seawater and origin of the Middle Ordovician dolomites in the Illinois Basin
This investigation focuses on the chemistry of dolomitization and the geochemical and petrographic characteristics of the Middle Ordovician limestones and dolostones in the Illinois basin.

Depositional characterization of the Eau Claire Formation at the Illinois Basin - Decatur Project: facies, mineralogy and geochemistry
The Cambrian-age Eau Claire Formation serves as the primary seal at the Illinois Basin – Decatur Project (IBDP), a one million tonne carbon capture and storage demonstration project located in Decatur, Illinois. The Eau Claire Formation conformably overlies the Mt. Simon Sandstone, the reservoir …

Relative timing of dolomitization and silica cementation in the Cambrian Potosi and Eminence Dolomites in the Illinois Basin, USA
The Late Cambrian Potosi and Eminence Dolomites of the Illinois Basin are currently being considered as targets for subsurface carbon capture, transport and storage (CCS) because of their extensive regional distribution and high intrinsic porosity and permeability. Drill core and outcrop samples …

Palynology of the Springfield Coal of the Illinois Basin (Middle Pennsylvanian) with quantitative comparison of spore floras and coal-ball peats and implications for paleoecological studies
Spores and coal balls from profiles in the Springfield Coal of the Illinois Basin were analysed to determine how quantitative spore floras can be used in paleoecological interpretations of Pennsylvanian-age coals. Laterally extensive sampling of spore profiles also was designed to evaluate lateral …

Petrography, Diagenesis and Depositional Models of the St. Louis Limestone, Valmeyeran (Middle Mississippian), Illinois Basin, u.s.a. (United States)
The Valmeyeran (Middle Mississippian) St. Louis Limestone of the Illinois Basin was studied through eight cores and six field sections. Detailed petrography of 1542 oriented thin sections led to recognition of 16 carbonate microfacies. The vertical succession, reciprocal (lateral and vertical) …

Coupling tough2 and SEAWAT variable-density models to understand potential geologic carbon sequestration impacts on groundwater resources
The Mt. Simon Formation, the basal sandstone reservoir in the Illinois Basin, is the storage reservoir for a geologic carbon sequestration (GCS) project in central Illinois (USA). The Mt. Simon is a highly saline reservoir at the injection location (Macon County), but its salinity decreases to the …
