Offshore staff

RIO DE JANEIRO Petróleo Brasileiro S.A. has filed the declaration of commercial viability for the oil accumulation in the northwest area of the Júpiter discovery evaluation plan in block BM-S-24 in the presalt layer of the Santos basin.

In the declaration sent to the National Oil, Natural Gas and Biofuels Agency, the consortium composed of Petrobras (80%) in partnership with Petrogal Brasil S.A. (20%) suggested that the new field should be called Sépia Leste. The field’s total recoverable volume is estimated at 130 MMboe.

The Sépia Leste field is approximately 250 km (155 mi) offshore Rio de Janeiro state, at a depth of 2,165 m (7,103 ft). During the exploration, the extension of the accumulation of the Sépia field (Transfer of Rights) for the Sépia Leste area was verified, characterizing to be a single oil deposit.

The Sépia field was declared commercially viable by Petrobras (operator) in September 2014 and presents reservoirs with excellent porosity and permeability characteristics and good quality oil (approximately 26º API).

The BM-S-24 consortium and Petrobras are discussing the unitization of the deposit comprising the Sépia and Sépia Leste fields by means of a production individualization agreement. The unitization process consists of enabling, through a single project, the development and production of a single deposit which encompasses concession areas belonging to more than one concessionaire.

If the area is considered as a single deposit, the production of the Sépia Leste field will be handled by the same system used in the Sépia field, whose operational start-up is scheduled for 2019.

The BM-S-24 consortium will have until February 2016 to conclude the appraisal of the discovery of the remaining area comprising the Júpiter discovery evaluation plan.
