The Barnett Shale is among the most significant onshore natural gas fields in North America and the largest in Texas, accounting for approximately 25% of all natural gas produced in the state in 2009. Our acreage dedication from Chesapeake Energy Corporation and Total in the Barnett Shale region is located primarily in Johnson and Tarrant counties, Texas, and is entirely within the Core and Tier 1 portions of the play, which are characterized by thicker natural gas bearing zones resulting in higher initial production rates.
We believe that the relatively low finding and development costs associated with drilling in the Barnett Shale will lead to extensive future development with Chesapeake Energy, estimating an inventory in excess of 4,000 potential gross drilling locations within our dedicated acreage. Our Barnett Shale gathering systems are comprised of approximately 780 miles of gathering pipeline with more than 1 billion cubic feet (Bcf) of daily throughput using more than 138,000 horsepower of compression.
