Petrobras has discovered a new post-salt oil reservoir in the ultra-deep waters of the Campos Basin.

The discovery was made at well 4-MLS-105D-RJS, informally known as Mandarim and located in the Marlim Sul field at a water depth of 1,874 meters, 126 km off the coast of Rio de Janeiro state.

The accumulation is located in Eocene-age arenaceous reservoirs at a depth of approximately 2,965 meters. Preliminary estimates indicate an oil column of 100 meters, with oil quality similar to the oil produced in Marlim field (13 to 16? API). Tests to evaluate the productivity of the reservoir are expected to be completed in 2013.

The well is located next to the P-56 platform, currently in operation in Marlim Sul field where production and flow structures are already in place, facilitating an early start-up, probably in 2014.
