RIO DE JANEIRO, May 7 (Reuters) - Brazil's state-run oil firm Petrobras will begin to drill off Colombia's coast at its Uchuva-2 well this month, said Chief Exploration and Production Officer Joelson Mendes on Tuesday. Mendes had previously said that the promising area off Colombia's coast could justify a large project to supply natural gas to the Andean country and for exports.
