text: Bossier Shale The Bossier Shale overlies about one-third of our 
  Haynesville Shale acreage. We estimate we could drill up to 2,600 net wells 
  on our Bossier Shale acreage in the future to develop our 205,000 net acres of Bossier 
  Shale leasehold. Because the Bossier lies above the Haynesville, horizontal wells 
  drilled just to the Bossier may not always hold Haynesville rights. As a result, 
  Chesapeake and other producers are drilling aggressively to hold all rights 
  through the Haynesville before the initial three-year term of a typical lease 
  expires, therefore not much Bossier drilling is yet underway. However, once our 
  leases are HBP (held by production) by Haynesville drilling, we plan to focus on 
  developing the Bossier Shale more aggressively beginning most likely in 2013.
