text: Barnett Shale Chesapeake is the second-largest producer of natural gas, the most 
  active driller and the largest leasehold owner in the Core and Tier 1 sweet spots of Tarrant 
  and Johnson counties. In January 2010, Chesapeake completed a joint venture and sold 25% of its 
  assets in the Barnett to Total E&P USA, Inc., a wholly owned subsidiary of Paris-based Total S.A. 
  (NYSE:TOT, FP:FP) (Total) for $2.25 billion in cash and drilling carries. During 2010 approx- 
  imately $480 million of Chesapeake’s drilling and completion costs in the Barnett were 
  paid by Total. Total will fund 60% of our share of future drilling and completion costs until an 
  additional $970 million of our costs have been funded, which we expect to occur by year-end 
  2013. We anticipate using an average of approximately 18 operated rigs in 2011 to further develop our 
  220,000 net acres of Barnett Shale leasehold, of which 205,000 net leasehold acres are located in the prime 
  Core and Tier 1 areas. On this acreage, we estimate we could drill up to 2,300 net wells in the years to come.
