Petrobras has declared commerciality for the north-western section of Brazil's Libra pre-salt area, stating proven reserves at 3.3 billion barrels of oil while renaming the ring-fenced area as Mero, writes Gareth Chetwynd.
Petrobras drilled a total of eight wells in Libra NW during a four-year appraisal phase, identifying a high quality reservoir with 29 degrees API crude.
With carbon dioxide accounting for 40% of the abundant associated gas, all gas will be injected for the Libra-1 FPSO and, for this reason, reserves are have so far been stated in oil only rather than oil equivalent, said Petrobras’ executive manager for Libra, Fernando Borges.
