Since early 1998, Chesapeake has built the largest inventories of onshore leasehold (15.3 million net acres) and 3-D seismic (30.8 million acres) in the U.S. On this leasehold, we have identified approximately 20 year inventory of an estimated 39,200 net drilling locations on which we can develop approximately 9.3 tcfe of proved undeveloped reserves and approximately 114 tcfe of risked unproven resources. Based on 10 year strip prices at 12/31/2011, Chesapeake has 19.9 tcfe of proved reserves and its risked unproved reserves together total approximately 134 tcfe. This inventory provides the opportunity to create sustained reserve and production growth for many years to come.
