Area of Mutual Interest

The Area of Mutual Interest (AMI) of the Chesapeake Granite Wash Trust is limited to the Colony Granite Wash formation and consists of approximately 45,400 gross acres (28,700 net acres) held by Chesapeake Energy Corporation. The AMI is identified on the map below.

The Colony Granite Wash formation is encountered at depths between approximately 11,500 and 13,000 feet. It lies between the top of the Des Moines formation (or top of Colony Granite Wash “A”) and the top of the Prue formation (or base of Colony Granite Wash “C”).

The Colony Granite Wash is a subset of the greater Granite Wash plays of the Anadarko Basin. The Colony Granite Wash is situated at the eastern end of a series of Des Moines-age granite wash fields that extend along the southern flank of the Anadarko Basin, approximately 60 miles into the Texas Panhandle.
