Bioceánico Gas Pipeline, also known as the Argentina-Paraguay-Brazil Gas Pipeline, is a proposed gas pipeline that would run from northwestern Argentina to southwestern Brazil, passing through Paraguay.

Location

The pipeline is proposed to run from a junction with the Gasoducto Norte in Campo Durán, Argentina to Campo Grande, Mato Grosso do Sul, Brazil. En route, the pipeline would pass through Pozo Hondo and Carmelo Peralta, Paraguay, and Porto Murtinho, Mato Grosso do Sul, Brazil.

Background

Main Line

In May 2024, Paraguay's Vice Minister of Energy and Mines confirmed that the Paraguayan government was studying potential development of a tri-national pipeline to transport fossil gas from Argentina through Paraguay to Brazil. A key goal for the pipeline would be to help Brazil compensate for the ongoing decline in gas exports from Bolivia. The proposed pipeline would extend for approximately 1050 km, including 110 km in Argentina, 530 km in Paraguay, and 410 km in Brazil. The project's development costs were estimated at between US $1.5 billion and US $2 billion.

The gas, originating in Argentina's Vaca Muerta region, would be transported north via the Néstor Kirchner Gas Pipeline and the Gasoducto Norte to Campo Durán (Salta province) in northwestern Argentina.

From Campo Durán, the new multi-national pipeline would run 110 km east through Argentina to Pozo Hondo in Paraguay, then continue east across Paraguay, paralleling the Ruta Bioceánica highway for 530 km to reach Carmelo Peralta on the Paraguay-Brazil border. From Porto Murtinho, Brazil, a final 410-kilometer segment would be constructed through Mato Grosso do Sul state to the pipeline's terminus in the capital city of Campo Grande.

In June and July 2025, the Paraguayan government confirmed its strong support for the project, confirming that it had signed MOUs (memoranda of agreement) with Argentina and Brazil to study the pipeline's technical, economic and environmental feasibility. Mauricio Bejarano, Paraguay's Vice Minister of Mines and Energy, expressed interest in earmarking some gas from the pipeline for power generation, to compensate for Paraguay's diminishing hydroelectric surplus.

Additional details for the Brazilian section

The pipeline's easternmost segment is known within Brazil as the Gasoduto Porto Murtinho–Campo Grande (Porto Murtinho–Campo Grande gas pipeline). The Brazilian government reported several additional details about this segment in a February 2025 report, including estimated development cost (R$6.119 billion), capacity (15 million m³/day), diameter (32 inches), and length (392 km). Note that this latter figure differs slightly from the 410 km length reported by other sources for the Brazilian section.

Expansion project

The pipeline's initial capacity was projected to be between 10 million and 15 million m³ per day. After the first three to five years of operation, a subsequent expansion project would potentially raise the total capacity to 30 million m³ per day.

Alternate route through Asunción, Paraguay

A shorter alternate route for the pipeline has also been proposed, running from a junction with Argentina's Gasoducto del Noreste in Formosa province to Asunción, Paraguay, then continuing north-northeast to Campo Grande, Brazil. This alternate route through Asunción would have the advantage of being shorter than the route through Pozo Hondo and Carmelo Peralta, but few details about this alternate route were available as of June 2024.
