Petrobras has qualified seven bids in a tender for the charter of high-specification drilling rigs to work offshore Brazil, signalling it will award combined contracts worth more than $3 billion as it seeks to replenish its fleet.

As reported exclusively in August by Upstream, the Brazilian oil giant received numerous proposals from five contractors.

The Petrobras bidding committee has recently concluded analysis of the offers and submitted for approval of the board the charter of seven units from four different drilling contractors, a well-informed source said.
