text: The SEC requires natural gas and oil companies, in 
  filings made with the SEC, to disclose proved re- 
  serves and permits the optional disclosure of 
  probable and possible reserves. While Chesapeake 
  has elected not to report probable and possible 
  reserves in its filings with the SEC, we have pro- 
  vided estimates in this report of what we consider 
  to be our “total resource base.” This term includes 
  our estimated proved reserves as well as “risked 
  and unrisked unproved resources,” which repre- 
  sent Chesapeake’s internal estimates of volumes of 
  natural gas and oil that are not classified as proved 
  reserves but are potentially recoverable through 
  exploratory drilling or additional drilling or recovery 
  techniques. Our estimates of unproved resources 
  are not intended to correspond to probable and 
  possible reserves, as defined by SEC regulations, 
  and are by their nature more speculative than 
  estimates of proved reserves and accordingly are 
  subject to substantially greater risk of being ac- 
  tually realized by the company.
