Pre-salt
Team Petrobras
The pre-salt layer is a layer of oil reserves located below a thick layer of salt on the seabed, where the oil is located. This geological formation is considered one of the largest oil discoveries in recent decades and is located mainly in the Santos and Campos basins.
The pre-salt layer is a specific geological formation where there are oil reserves. In addition to the pre-salt layer, it is possible to extract oil from other reservoirs, including on dry land.
The pre-salt layer is essential to enable the energy transition because it has highly productive oil wells and the lowest emission of polluting gases in the global sector. In practice, the pre-salt layer is a strategic area for oil exploration and production in Brazil, and allows us to generate the energy the country needs and cause less impact on the environment!
The pre-salt discovery was made by Petrobras in 2006, off the Brazilian coast.
The pre-salt layer is important to guarantee Brazil’s energy security — that is, to generate energy for everyone and meet the still existing demand for oil.
Furthermore, production in the pre-salt layer also helps in the social and economic development of the country, with new jobs and income.

Oil exploration in the pre-salt layer is carried out by FPSO platforms at depths of up to 7,000 meters. These platforms extract oil and natural gas from the pre-salt layer and store it.
The oil is then transferred to a relief vessel, which transports the oil to an onshore terminal. Natural gas is sent to the ground through pipelines and/or is reinjected into the reservoir.
