The study also proposes new investments and the resumption of refinery projects abandoned by Petrobras after the state-run oil company decided to focus on production from the pre-salt fields as it recovered from the Car Wash corruption scandal.

Among the proposals is the possibility of Petrobras regaining ownership of the Bahia refinery, the largest refining asset sold in 2021 by the company, now owned by Acelen of the Mubadala group, said William Nozaki, on the Workers Party team advising Lula on Petrobras affairs.
