Authors' affiliations:  consultant and Illinois State Geological Survey
Age:  Mississippian
Formation:  Aux Vases Sandstone
Location:  Storms Consolidated Field, Illinois Basin, White County, Illinois, United States
Well:  Rudolph 26 Tract 11A
Depth range:  2925 - 2950 feet.  
Depositional environment:  “a series of shallow marine bars separated by nonreservoir areas of siltstone, shale, and shaly sandstone.”
Lithology:  Fine to medium grained quartz arenites and subarkoses.  
Alteration:  “Based upon x-ray diffraction of samples from a continuous whole-rock core at the 26 Rudolph well, these sandstones contain 60-80% quartz, 3-9% feldspar, 6-20% calcite, and 2-9% clay minerals. Dominant clays include illite (1-9%), mixed-layer illite/smectite (1-5%), and iron-bearing chlorite (0.5-3.3%).  Clays appear authigenic in origin and are absent at grain-to-grain contacts.  Cements include calcite, clay minerals, and minor quartz overgrowths.  Sandstones with maximum reservoir quality are poorly cemented, very friable, and contain mostly clay cement.  Both primary and secondary porosity are present, with the latter resulting from dissolution of early calcite cement and feldspar grains.”
Production:  oil 
Core measurement conditions:  not stated.
