Petrobras said on Nov. 23 it had been unable to produce 2.29 million barrels of oil and 48.4 million cubic meters of natural gas during a strike that began on Nov. 1.

The company said the majority of unions representing oil workers had voted to end the strike, thought to be the most disruptive in 20 years. The largest union FUP proposed ending the strike on Nov. 14 though some hold-out unions continued.
