File No. 1-15106

Dear Mr. Horowitz:

By letter dated November, 30, 2016, the Securities and Exchange Commission (the “Commission”) provided certain comments related to the annual reports on Form 20-F for the fiscal year ended December 31, 2015, by Petróleo Brasileiro S.A.—Petrobras (“Petrobras”).

The Commission asked Petrobras to respond to such comments or to inform the Commission of when it will respond within ten (10) business days, which deadline would have elapsed on December 14, 2016. On December 13, 2016, counsel for Petrobras contacted Ms. Diane Fritz by telephone in order to request a ten (10) business day extension as of the deadline, which request was granted. Consequently, Petrobras undertakes to submit a response to the Commission’s comments on or before December 28, 2016.
