RIO DE JANEIRO, Sept 16 (Reuters) - Brazil's biggest oil field Libra, located off the coast of Rio de Janeiro, will cost $80 billion to develop, an executive at consortium member Total said on Tuesday.
Libra, in the Santos Basin, contains an estimated 8 billion to 12 billion barrels of oil.
"(Libra) will give us a return on our investment for many decades," Ladislas Paszkiewicz, Total's vice president for exploration and production in the Americas, said at a conference in Rio de Janeiro.
Paszkiewicz did not offer any further details on the financial plans for the project.
The Libra consortium is led by state-run oil firm Petroleo Brasileiro SA, or Petrobras, with a 40 percent stake. Total and Royal Dutch Shell Plc both have 20 percent while China's National Petroleum Corp and CNOOC have 10 percent each.
