The Paoli Formation, Paoli Limestone, or Paoli Chert is a geologic formation in Indiana, Illinois, Kentucky and Missouri. This formation contains members that are known hydrocarbon reservoirs.

Stratigraphy

Downeys Bluff Member

The Downeys Bluff Member is the uppermost or top member. It is grey, light to medium in hue. The limestone is fairly clean, with small amounts of clay and shale. It contains a variety of textures, the most noted are micritic, oolitic and skeletal.

Popcorn Sandstone Member

Popcorn Sandstone Member or Popcorn Sandstone Bed is the lowest member of the Paoli and marks the base of the Chesterian Series. It is not found throughout the entire Paoli. The Popcorn is sometimes included with the Aux Vases Member in other areas it is its own separate member.
