Atlanta Field

155 MM bbl


Water depth:

1,500 M



Our history in ultra-deep waters – environment in which we were the first Brazilian independent company to operate in the pre-salt exclusion zone of the Santos Basin – consolidated our experience and delivery capacity.


We operating the Atlanta Field located in Block BS-4, in the Santos Basin, with 100% participation – a project that required overcoming challenges and applying the most advanced offshore engineering concepts.


Atlanta was our second farm-in agreement after going public in 2011, when we acquired a stake and the operation of the Block, with an investment of US$157.5 million.


Operational efficiency and financial resilience


In 2018, we started the production through an Early Production System (EPS) – comprising three wells connected to the FPSO Petrojarl I. There are already more than 21 million barrels produced in the SPA and, after more than 3 years, we have acquired knowledge, validated assumptions and conducted important technical studies for the implementation of the Full Development System (FDS).


With the information obtained in the EPS, we prepared a new development plan for the FDS, more efficient operationally and with a significant reduction in investments. The FDS will include the drilling of additional wells, totaling up to 6 horizontal wells, connected to a a new FPSO with 50.000 bopd capacity and store up to 1,600.000 barrels of oil – the total storage capacity is almost ten times larger than the FPSO currently in production. These features will optimize costs and offloading operations.


Work is underway to expand the water treatment capacity of the FPSO Petrojarl I and allow the extension of its operation until 2025. This work should be completed by the end of this year.


The Atlanta Field has heavy oil, with 14º API and low sulfur content, less polluting and in line with IMO 2020 maritime fuel regulations.
