Newfield Exploration Company (NFX) reported 2009 production figures for its operations in the Woodford Shale in the Arkoma Basin of Oklahoma. Newfield Exploration reported gross production of 323 million cubic feet equivalent of natural gas per day, or 184 million cubic feet per day on a net basis. In 2010, Woodford Shale production will increase 20% over 2009 levels.
The company attributed the production growth to the use of super extended lateral (SXL) completions, which it defines as a lateral length of more than 5000 feet. Newfield Exploration provided examples of two recent wells into the Woodford Shale.
The Madison 1H-15W was drilled with a lateral length of 9,983 feet and was completed with a 20 stage hydraulic fracturing operation. The well had initial production of 13.5 million cubic feet of natural gas.
The Martin 1H-15E was drilled with a lateral length of 9,405 feet and was completed with a 19 stage hydraulic fracturing operation. The well had initial production of 13.5 million cubic feet of natural gas.
Newfield Exploration has twenty wells awaiting completion in the Woodford Shale, including five categorized as SXL’s. The company estimates that the cost to drill and complete horizontal wells in the Woodford shale range from $7-8 million, assuming an average lateral length of 6000 to 7000 feet.
