About the Granite Wash

The Granite Wash is an oil and gas field in Texas and Oklahoma.  Described as a “wash” formation due to the granite weathering and reconstitution of the original rock, the Granite Wash formation covers a large area, from the Texas Panhandle to Western Oklahoma and Southern Kansas.  There are several oil and natural gas “pay zones” located between 11,000 and 17,000 feet.
