The BM-SEAL-4 and BM-SEAL-4A areas were acquired in 2000, in the 2^nd^ Bidding Round under a Concession Agreement. The BM-SEAL-10 and BM-SEAL-11 areas were acquired in 2004, in the 6^th^ Bidding Round under a Concession Agreement.

In the declarations sent to the regulator, the names suggested for the new fields were: Budião, Budião Noroeste, Budião Sudeste, Palombeta, Cavala, Agulhinha, and Agulhinha Oeste.

Petrobras intends to develop production from the above fields in two modules, called Sergipe Deepwater (SEAP) I and II, which foresee the installation of two FPSO-type platforms.

The first platform, planned to serve the SEAP I module, will be the P-81, scheduled to start production in 2026, with capacity to produce 120 thousand barrels of oil/condensate and flow 8 million m³ of gas per day. The second platform, planned to serve the SEAP II module, is in the contracting planning phase and is scheduled to start production after the 2022-2026 Strategic Plan horizon.

The SEAP I and II modules include the implementation of a new gas flow system connecting the two production modules to the Sergipan coast, with a capacity of 18 million m³ per day, which is in the planning stage, and scheduled to start operating after the 2022-2026 Strategic Plan horizon.
