Since early 1998, Chesapeake has built the largest inventories of onshore leasehold (15.6 million net acres) and 3-D seismic (31.8 million acres) in the U.S. On this leasehold, we have identified approximately a 20 year inventory or an estimated 39,400 net drilling locations on which we can develop approximately 9.7 tcfe of proved undeveloped reserves and approximately 112 tcfe of risked unproven resources. Based on 10 year strip prices at 3/31/2012, Chesapeake has 19.9 tcfe of proved reserves and its risked unproved reserves together total approximately 132 tcfe. This inventory provides the opportunity to create sustained reserve and production growth for many years to come.
