Coalbed gas origin and distribution in the southeastern Illinois Basin
… contain biogenic methane that in some coal basins forms easily accessible and large amounts of coalbed methane (CBM). Economically important biogenic CBM occurs not only in coals of low rank but also in higher rank coals where uplift and brine dilution initiated microbial methanogenesis. …

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
… Formation and the Mt. Simon Formation at the Illinois Basin – Decatur Project (IBDP), a large-scale carbon capture and storage project, is developed. The extended Morris OAT method (Morris, 1991; Campolongo et al., 2007) is used to assess the sensitivity of the pressure response due to brine …

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 …

High-Resolution Sequence Stratigraphy of Late Mississippian (Chesterian) Mixed Carbonates and Siliciclastics, Illinois Basin
… in the tectonically-active, tide-dominated Illinois basin during the Late Mississippian greenhouse to icehouse transition. Detailed, lithologic cross-sections were constructed through the Chesterian Ste. Genevieve through Glen Dean interval which show an upward change in character from …

Carbonate Microfacies and Depositional Environments of the Kinkaid Formation (Upper Mississippian) of the Illinois Basin
… 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
… targets for hydrocarbon exploration in the Illinois Basin. Though there is little literature addressing the geologic factors controlling hydrocarbon accumulation in sub-Pennsylvanian paleovalleys basin-wide, much work has been done to identify the Mississippian-Pennsylvanian unconformity, …

Subsurface dolomitization and porosity occlusion within Early to Middle Ordovician strata of the Illinois Basin, USA
… obtained from drill cores and outcrops in the Illinois Basin indicate that subsurface dolomitization locally reduced primary porosity, and that the degree of reduction changes with location. Specifically, porosity occlusion by dolomitic cementation is pronounced in the Shakopee and Everton on …

Upper mantle reflectivity beneath an intracratonic basin: insights into the behavior of the mantle beneath Illinois basin.
… the lower crust and uppermost mantle beneath the Illinois basin have been derived from reprocessing of several hundred kilometers of industry seismic reflection data using extended vibroseis recorrelation. The recorrelation was based on extending an originally 4-s correlated record, acquired with …

Relative timing of dolomitization and silica cementation in the Cambrian Potosi and Eminence Dolomites in the Illinois Basin, USA
… 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 …
