(WO) – CNOOC Limited announced that the Buzios5 project has commenced production safely.
The Buzios oil field is located in the Santos basin, southeast offshore of Brazil, with a water depth of 1,900 to 2,200 meters. It is the largest deep-water pre-salt oil field in the world, with a daily production of about 600,000 bbl at present.
Buzios5 is the fifth phase of oil field development. It will be developed with an FPSO and subsea production system. The project has already drilled 5 producing wells and 5 injectors. These wells will produce up to 150,000 bbl of crude oil, 6 MMcm of natural gas and inject 220,000 bbl of water per day.
