The Midcontinent Granite Wash is a series of tight gas plays (Lard Ranch, Buffalo Wallow, Stiles Ranch, and Colony West) that runs from the Texas Panhandle to Southwest Oklahoma. There is some oil production in the Granite Wash, mainly in Oldham and Gray counties in Texas. The sandstone reservoir is about 160 miles long and 30 miles wide. Operators are using both horizontal and vertical drilling to produce reserves from this longtime target.
Economic rates are achieved by multi-stage, slickwater fracture treatments and close attention to costs. There are over 2600 operating wells in the Granite Wash, and some of the operators include Chesapeake Energy, Newfield Exploration, Penn Virginia, Cimarex Energy, Questar, Linn Energy, Forest Oil, Apache Corp., BNK Petroleum, Devon Energy, and Cordillera Energy Partners III.
