BP's giant Brazil oil discovery attracts Petrobras interest
BP is in talks to sell a stake in its Bumerangue offshore oil discovery to Petrobras, which could bring together two major deepwater operators. The discovery, with 8 billion barrels of liquids in place, is BP's largest in 25 years but faces technical challenges due to high CO2 content. Petrobras is evaluating the proposal, but no agreement is guaranteed. BP aims to secure a partner to share costs before making a final investment decision.
