...In April 2011, the Leiv Eiriksson commenced a contract with a term of approximately six months with Cairn Energy plc, or Cairn, for drilling operations in Greenland at a maximum operating dayrate of $560,000 and a mobilization fee of $7.0 million plus fuel costs. The contract period is scheduled to expire on October 31, 2011, subject to our customers option to extend the contract period through November 30, 2011.
Following the expiration of its contract with Cairn, the Leiv Eiriksson is scheduled to commence a contract with Borders & Southern for drilling operations offshore the Falkland Islands at a maximum operating dayrate of $530,000 and a $3.0 million fee payable upon commencement of mobilization as well as mobilization and demobilization fees, including fuel costs, of $15.4 million and $12.6 million, respectively. The contract was originally a two-well program at a maximum dayrate of $540,000; however, on May 19, 2011, Borders & Southern exercised its option to extend the contract to drill an additional two wells, which it assigned to Falkland Oil and Gas Limited, or Falkland Oil and Gas, and the maximum dayrate decreased to $530,000. Borders & Southern has the option to further extend this contract to drill an additional fifth well, in which case the dayrate would increase to $540,000.
The estimated duration for the four-well contract, including mobilization / demobilization periods, is approximately 230 days, and we estimate that the optional period to drill the additional fifth well would extend the contract term by approximately 45 days........
