The deal comes as Petrobras is struggling to overcome the consequences of the large-scale corruption probe.
Petrobras was headed by former Brazilian President Dilma Rousseff in 2003-2010, who faced public outrage after the company’s corruption schemes were revealed in 2014.
Several government functionaries were discovered to have been signing contracts at 3 percent commission fee. The money received from the scheme was used for bribing police and public officials. Those behind the corruption scheme made about $3.8 billion, according to the Brazilian authorities.
