There have been some mixed signals coming from Brazil's largest oil company, Petrobras (NYSE:PBR). The company has been able to pick up its production numbers lately thanks to some of its idle rigs coming back on line. Also, the company seems to be lining itself up well to expand operations into the pre-salt layer, which will be auctioned off for the first time in October. The problem, though, is that the company will need to add to its already large debt load to make it happen.

Doing business in Brazil isn't easy for oil companies, but for Petrobras to expand oil production, it will need to get some outside help. In this video, contributors Tyler Crowe and Aimee Duffy discuss some of the other issues facing Petrobras, and look at some companies that are lining themselves up to make a splash in Brazil.
