The Route 6b Gas Pipeline is a proposed natural gas pipeline off the Atlantic coast of southeastern Brazil.

Location

The proposed pipeline would run west from the offshore pre-salt fields of Brazil's Campos Basin to Açu Port in the state of Rio de Janeiro.

Background

In May 2019 Brazil's Secretary of Oil and Gas of the Ministry of Mines and Energy, Márcio Félix, stated that Petrobras was considering building more pipeline networks, to be called Routes 4, 5 and 6.

Two separate alternatives for the Route 6 pipeline have been proposed, known as Route 6a and Route 6b. The Route 6b alternative calls for the construction of an 118-kilometer, 14-inch pipeline with a capacity of 12 million cubic meters per day and an estimated development cost of R$ 2.49 billion (2.49 billion Brazilian reais). The pipeline would terminate at the Port of Açu in Rio de Janeiro state and would potentially supply several new gas plants that have been proposed in the area.

A November 2021 update of the Brazilian government's offshore gas infrastructure plan continued to list the Route 6a pipeline as an active project, noting that it was still in the "initial studies" phase. A more recent edition of the plan released in April 2024 made no specific mention of Route 6a or 6b; however, the introduction implied that all projects listed in previous editions remained under consideration ("É importante destacar que os projetos já analisados em edições anteriores do PIPE (PIPE 2019 e PIPE 2021) não devem ser desconsiderados.")

As of August 2025, with no concrete news about the pipeline in more than two years, the project was presumed to be shelved.
