Ocean Rig UDW Inc. has been awarded extensions of the drilling contracts for its two ultradeepwater drillships, the Ocean Rig Corcovado and the Ocean Rig Mykonos, by Petrobras for drilling offshore Brazil, according to a press release. The contracts extensions are subject to partner approvals. The term of each extension is for 1,095 days with a total combined revenue backlog of over $1.1 billion, excluding reimbursement by Petrobras for contract-related equipment upgrades. The new contracts will commence in direct continuation from the end of the current agreements with Petrobras in the first and second quarters of 2015.

Ocean Rig also signed an amendment with Total E&P Angola to extend the date by which Total E&P Angola should exercise the option to extend the term of the contract for two additional one-year periods. The first option is now exercisable until Feb. 27, 2015, and the second option exercisable within one year after the date of exercise of the first option.
