  Chesapeake was one of the first to utilize modern horizontal drilling methods and has assembled 
  an unrivaled leasehold position in numerous horizontal liquids-rich plays in the basin. Chesapeake 
  will continue drilling with a focus on the Granite Wash, where rates of return are the highest in our 
  company, and with an increasing focus on the Cleveland, Tonkawa and Mississippian liquids-rich 
  unconventional plays. We estimate we could drill up to 11,400 net wells on our Anadarko Basin 
  acreage in the future and plan to utilize an average of 31 operated rigs in 2011 to further develop 
  our current 1.7 million net leasehold acres.
