Brazil's Petrobras says its value could increase by almost half by 2021

 Brazilian state-run oil firm Petrobras expects to increase its equity value by roughly 45% by 2021, in large part by cutting costs and divesting non-core assets, it said in a presentation released.

Capital expenditure from 2020 to 2024 will be concentrated in Brazil’s offshore “pre-salt” formation, with a special emphasis on its Buzios field, Petroleo Brasileiro SA, as the firm is formally known, said.
