Campos Basin is a petroleum system located offshore of Rio de Janeiro, Brazil. It has a total area of 100,000 km², with 40 fields discovered and operated by Petrobras. Two major oil fields are Marlim and Albacora. Marlim is the largest field, located NorthEast of the Basin, 110 km offshore in water 650 to 1050 m deep. Marlim produces crude oil over 80,000 m³ (500,000 barrels) per day.
Total daily production of Campos Basin is 175,000 m³ (1.1 million barrels) of oil and 17.36 million m³ of natural gas per day. The estimates are that in 2006, Campos Basin will be producing 250,000 m³ (1.6 million barrels) of oil per day.
The confirmed reserves are 1.1 million m³ (7.21 billion barrels) of oil and condensate, and 101.53 billion m³ of natural gas.
Considered the biggest oil reserve in the Brazilian Continental Platform, the CamposBasin measures some 100,000 square kilometers and ranges from the State of EspÃrito Santo, near the city of Vitória, to the Arraial do Cabo, off the northern coast of the State of Rio de Janeiro.
The first was the P-52, which was baptized last June and is currently in its final testing phase to depart to the CamposBasin.
Exploration was kicked-off in the CamposBasin in late 1976, at well 1-RJS-9-A, which gave rise to the Garoupa field, located at a depth of 100 meters.
As is well known, the north portion of the CamposBasin is situated in Espirito Santos's waters extending to the so-called geological arch of Vitória.
As known, the Espirito Santo coast is divided in two sedimentary basins: in the north, the Espirito Santo Basin and in the south it corresponds to the north portion of the CamposBasin
