Ultrahigh-resolution paragenesis of the Cambrian-age Mt. Simon Sandstone at a burial depth of 1.8-2.1 km, Illinois basin, USA
… to reconstruct the paragenesis of Cambrian-age Mt. Simon Sandstone quartz arenites buried at 1.8-2.1 km within the Illinois Basin. Results have yielded valuable new insight into the evolution of this important subsurface reservoir and provided the depositional and diagenetic history required to …

Potassic alteration of Cambrian-Ordovician sandstones and Precambrian basement rocks of the North American midcontinent
In Hole UPH-3 the Mt. Simon Sandstone contains three distinct diagenetic zones: an upper K-feldspar overgrowth zone, an underlying sericite zone, and a lowermost feldspar zone. Uppermost Precambrian basement exhibits potassic alteration similar to the overlying Mt. Simon Sandstone. Sericite in the …

Improving capabilities of pore-scale modeling of multiphase flow for geological storage of CO2
… to large heterogeneous cores. A heterogeneous Mt. Simon sandstone sample is characterized in terms of morphology and CO2-brine flow properties. 3D rock images are investigated to assess the REV size and heterogeneity. Three distinct simulation approaches are applied to simulate the displacement …

Geochemical and geomechanical alteration of sandstone reservoir rock and shale caprock under representative geological carbon sequestration conditions
… low-pH brine on the geomechanical properties of sandstone reservoir rock and shale caprock. In the first study, Mt. Simon Sandstone is exposed to either N₂-saturated or CO₂-saturated brine at reservoir pressure and temperature in a batch system. The next two studies focus on acidified brine flow …

Migration and trapping of CO₂ in saline aquifers
… study the migration and trapping of CO 2 in the Mt. Simon Sandstone, a large deep saline aquifer in the Midwestern United States that is considered to be a promising candidate for geological CO 2 storage.

Depositional characterization of the Eau Claire Formation at the Illinois Basin - Decatur Project: facies, mineralogy and geochemistry
… Eau Claire Formation conformably overlies the Mt. Simon Sandstone, the reservoir for the IBDP. At the IBDP site, analysis of drill core and geophysical logs reveals the Eau Claire consists of two major lithostratigraphic units: a siliciclastic dominant lower unit and a carbonate dominant upper …

Relative timing of dolomitization and silica cementation in the Cambrian Potosi and Eminence Dolomites in the Illinois Basin, USA
… Dolomites. Quartz cements in the Cambrian Mt. Simon Sandstone and the overlying Cambrian Eau Claire Sandstone yield early-to-late stage cementation δ18O values (28-18‰ VSMOW), which suggest they were derived from Si-rich source waters during subsidence and associated pressure solution. This …
