The New Albany Shale is located in the Illinois Basin in portions of southeastern Illinois, southwestern
Indiana, and northwestern Kentucky159. Similar to the Antrim Shale, the New Albany occurs at depths between 500 ft and 2,000 ft and is a shallower, water-filled shale with a more CBNG-like character than the other gas shales discussed in this section. The New Albany formation is a Devonian- to Mississippian-age shale bounded by limestone above (Rockford Limestone) and below (North Vernon Limestone).
