Project Profile
Location: Campos Basin, South-eastern Brazil
Start-up Year: May 2010
Oil production: 44,000 bpd
Water depth: 1,478m
The Cachalote oil field is located in the Campos Basin in south-eastern Brazil. The Campos Basin is located beneath the coastal plain in the western portion of the South Atlantic Ocean and covers an area of 100,000km². It was discovered by drilling well ESS-116 in November 2002 at a depth of 1,478m. It contains 40 fields operated by Petrobras. The basin has more than 30 hydrocarbon accumulations, which contribute to approximately 60% of Brazil\'s oil production. Reserves are accounted majorly from lacustrine calcareous black shales which are deposited in a closed Upper Neocomian lake system.
The development of the field started with a pilot phase which involved the drilling of a production well that produced oil in 2008. Phase I involved the drilling of eight production wells and three injection wells. The first production well, 7-CHT-5HA-ESS, was estimated to produce 22,000bpd. Field production doubled to 44,000bpd in June 2010.
Pilot phase production was carried out by using the floating production, storage and offloading vessel (FPSO) Seillean. The FPSO was deployed at the field in late 2008. Phase I production is being carried out using the FPSO Capixaba.
