[1/3] A worker walks inside the Brazil's Petrobras P-66 oil rig in the offshore Santos basin in Rio de Janeiro, Brazil September 5, 2018. Petrobras' main bet on replenishing its reserves had been the Equatorial Margin, some 2,200 km of deepwater and ultra-deepwater assets along Brazil's northern and northeastern coast. According to one of the sources, the Equatorial Margin has been the company's "Plan A, B, and C" for restocking reserves. In March, Reuters reported that Petrobras was among at least 10 companies including Shell and Chevron to consider bidding on a Guyana oil auction, now scheduled for July. Such projects could also add scope for foreign expansion, said Mauricio Tolmasquim, Petrobras' chief energy transition and sustainability officer.
