Petrobras currently holds a 40% non-operational interest in Blocks ES-M-598, ES-M-671, ES-M-673 and ES-M-743, and a 50% operating share in ES-M-596.
Norwegian oil company Equinor and French major Total hold the remaining interests but are currently transferring their stakes in the blocks to Petrobras.
Once this completes Petrobras will own 100% interests in three of the concessions and 80% in the remaining two.
Petrobras yesterday announced it would sell down an interest in each of the blocks to new joint venture partners.
It said in a media release its planned divestment aimed "maximizing value for shareholders" and "optimizing its portfolio." The sale is part of its previously announced US$30 billion divestment program aimed at completing in 2024.
"The concessions are strategically positioned in relation to the post-salt discoveries in areas known as Parque dos Deuses, Parque dos Doces and Parque dos Cachorros, in the Espírito Santo Basin," Petrobras said.
"[The blocks have] potential to prove significant volumes and establish a position in a new exploratory frontier both pre-salt as well as post-salt."
Interested parties have until June 10 to apply.
