The Fayetteville Shale is a geologic formation of Mississippian age (354–323 million years ago) composed of tight shale within the Arkoma Basin of Arkansas and Oklahoma.[4][7] It is named for the city of Fayetteville, Arkansas, and requires hydraulic fracturing to release the natural gas contained within.
