  • What's new in production

    Victor A. Schmidt, Drilling Engineering Editor

    Most everyone has heard of the three most important unconventional shale plays in the US: the Barnett Shale in Texas, Fayetteville Shale in Arkansas and Marcellus Shale, which stretches from Kentucky northeast across West Virginia and up into New York state. But there are many other shales that are being opened as new resource plays. Some of these less well-known plays include the Woodford Shale in Arkansas and western Oklahoma, Lower Huron Shales in the Appalachian Mountain states and the Haynesville Shale in Louisiana. New trends are opening in Oklahoma’s Anadarko Basin, including the Colony Granite Wash in Washita and Custer Counties. It has been tested and found productive with wells yielding good gas flows. Chesapeake Energy now has 12 wells producing 40 MMcfd (net). In southwestern Oklahoma and the Texas Panhandle, the Mountain Front Granite Wash is being drilled along the 150-mi Mountain Front region.
