Brazil’s semi-public multinational energy corporation, Petrobras, said oil spilled near Rio de Janeiro from a pipeline connecting a central Atlantic Ocean terminal with a refinery on Friday.
A spokesman representing workers of the refinery said the oil spill polluted a Brazil coastal area and seeped out into the ocean.
The oil spilled from an ORBIT pipeline, used to carry crude oil.
The pipeline runs 123 kilometres from Angra dos Reis, the place where the corporation unloads its biggest tankers to the Duqe de Caxias Refinery (REDUC), where the oil is turned to other fuels such as gasoline and diesel.
No sufficient information was given by the oil company Petrobras about the amount of oil that was spilled.
Petrobras' investments represent 2 percent of Brazil's gross national product.
Rio de Janeiro's Costa Verde also known as "Green Coast" is one of Brazil's most popular touristic regions.
The oil company claimed the oil leak took place in a struggle to steal fuel.
