Atlanta Field

103.1 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 50% 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 15 million barrels produced in the SPA and, after more than 2 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 8 horizontal wells, connected to a 50 kbopd capacity FPSO – the bidding process for this new FPSO has already started and is scheduled to be concluded in the first quarter of 2022.


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