Vega Pléyade Gas Pipeline

From Global Energy Monitor


This article is part of the Global Fossil Infrastructure Tracker, a project of Global Energy Monitor.

Vega Pléyade Gas Pipeline, known locally as Gasoducto Vega Pléyade, is an operating gas pipeline running from the Vega Pléyade offshore gas and condensate field to Tierra del Fuego, Argentina.


The pipeline starts at the Vega Pléyade offshore platform and runs to the Rio Cullen and Cañadon Alfa onshore treatment facilities in Tierra del Fuego, Argentina.[1][2]

Operated by Total and owned jointly by Total, Wintershall Energía and Pan American Energy, the Vega Pléyade project was launched in 2013 to develop the natural gas and condensate fields of the Cuenca Marina Austral 1 (CMA-1) concession, 20 kilometers east of Bahía San Sebastián in the Argentine Sea off the coast of Tierra del Fuego. The project comprises a wellhead platform in 50 meters of water linked to to Total-operated gas processing facilities at Rio Cullen and Cañadon Alfa on the Argentine mainland by a 77-kilometer, 10-million-cubic-meter-per-day pipeline.[1][2][5]

Vega Pléyade is the world's southernmost natural gas project. The field lies 2,900 km south of Buenos Aires, in raging seas buffeted by strong currents and winds of up to 180 km/hour, with winter temperatures dropping as low as -20°C.[3][4]

Construction of the offshore platform and pipeline was completed in two and a half years.[1] The pipeline began transporting natural gas in February 2016 and was officially inaugurated in June 2017 by Argentina's Minister of Energy, accompanied by officials from Total, Wintershall and Pan American Energy.[6]

Within its first year of operation, Vega Pléyade was already producing 7% of the country's natural gas supply, making Tierra del Fuego Argentina's second leading gas-producing province after Neuquén.[7] By 2018, Vega Pléyade had raised its share of national production to 8% and had increased natural gas output from Tierra del Fuego by 33%.[8]

As of July 2020, gas production at Vega Pléyade was temporarily suspended due to Argentina's economic crisis and falling gas prices.[9]
