Gasene Gas Pipeline, also known as the Southeast-Northeast Interconnection Gas Pipeline or Gasoduto da Integração Sudeste-Nordeste, is an operating natural gas pipeline running through the states of Rio de Janeiro, Espírito Santo, and Bahia, Brazil.


The pipeline runs from the Cabiúnas Terminal in Rio de Janeiro state through Vitória and Cacimbas (Espírito Santo state) to Catu (Bahia state), Brazil.[1]

The Southeast Northeast Interconnection Gas Pipeline (Gasene) pipeline system connects Brazil's southeastern gas system to its northeastern gas system and creates a common gas market in Brazil.[11] At its northern extremity in Catu (Bahia state), the pipeline connects to TAG's Catu-Itaporanga gas pipeline, facilitating the transport of gas to states throughout northeastern Brazil.


The Gasene pipeline officially has the capacity to transport up to 20 million m3 of fossil gas per day.[4] However, at the time of its inauguration in 2010, it was only transporting half that amount, with the expectation that it would eventually reach its full capacity through the addition of compression stations.[12] The pipeline continued to operate at half capacity over its first decade of operation, but recent developments - including the passage of Brazil's new gas law in 2021, the opening of the Brazilian gas market to competition, and an increase in offshore domestic gas production - have prompted moves to reinforce the pipeline's working capacity.[12] As of May 2023, pipeline operator TAG had announced plans to add a new compression station in Itajuípe, Bahia, with the goal of increasing capacity by 3 million m3 per day by 2026.[12]


The original operator of the Gasene system was Transportadora GASENE S.A., a subsidiary of Petrobras. In January 2012, Transportadora GASENE was incorporated into TAG (Transportadora Associada de Gás S.A.).[13]

In April 2019, a joint venture formed by French energy giant Engie and the Canadian institutional investor CDPQ (Caisse de dépôt et placement du Québec) announced that it would purchase 90% of TAG's transport infrastructure, including the Gasene gas pipeline, from Petrobras for US$8.6 billion.[14] The sale to Engie/CDPQ received final approval from Petrobras in June 2019.[15]

In July 2020, Engie and CDPQ acquired Petrobras's remaining 10% stake in TAG for US$206 million, and the two companies now share 100% ownership of the Gasene pipeline.[3]

Pipeline sections

GASENE starts from the Cabiúnas Terminal in Rio de Janeiro and runs to the city of Catu in Bahia. The project comprises the following sections:

  • Cabiúnas - Vitória, Brazil (GASCAV)
  • Vitória - Cacimbas
  • Cacimbas – Catu (GASCAC)[7]

GASCAV pipeline

The Cabiúnas-Vitória pipeline is a 303 km (188 mi) long pipeline with a 710 mm (28 in) nominal diameter and maximum capacity of 7.5 billion cubic meter (bcm) of gas per year. This section has two compressor stations. It is interconnected by a 10 km (6 mil) long branch line with Anchieta.[7] This section was designed and constructed by Chinese oil company Sinopec and began operating in February 2008.[9][16]

Vitória - Cacimbas pipeline

Vitória – Cacimbas section is a 130 km (81 mi) long pipeline with a diameter of 16 inches, which was completed in November 2007.[8][9]

GASCAC pipeline

The construction of the Cacimbas - Catu pipeline started in May 2008 and was completed in 2010. It is 954 km (593 mi) long, with a diameter of 710 mm (28 in). The pipeline was designed, engineered, and built by Sinopec and financed by China Development Bank.[17]
