Securities investors are focused on the short term and will do well with this company in the 1-3 year time frame even as oil production peaks and crashes in all major world markets.
Brazil is functionally corrupt. They will continue to be successful in protecting their oil market from outside penetration because there is an even greater gap between the haves and have nots and this makes corruption even more "functional" for those who benefit (like PBR)when compared to other corrupt oil oligopolies like the USA.
