The board of directors for Brazilian oil firm Petrobras is meeting Friday and is expected to name a new chief executive officer later in the day.
Brazil's state oil company is in crisis amid an expanding corruption investigation into a long-running kickback scheme on its contracts.
Several top executives from Brazil's biggest construction and engineering firms already are jailed and charged, along with a handful of former Petrobras executives.
It was on Wednesday that CEO Maria das Gracas Foster and five other top Petrobras executives resigned. None are facing charges in the corruption scandal — but authorities say the investigation is still in its beginnings stage.
Prosecutors say the kickback scheme involved at least $800 million in bribes and other illegal funds in exchange for inflated Petrobras contracts.
