Centro Oeste Gas Pipeline, known locally as Gasoducto Centro Oeste, is a natural gas pipeline in Argentina.[1][2]


The Gasoducto Centro Oeste runs from the Loma La Lata gas field in Neuquén province to the San Jerónimo compressor plant in Santa Fe province, where it connects with TGN's main north-south pipeline, the Gasoducto Norte Gas Pipeline.

Compressor stations along the pipeline's route include Puelén, Cochico, La Mora, Beazley, Chajan, La Carlota and General Baldissera. At Beazley, a spur pipeline branches west-northwest to the La Paz compressor station in Mendoza province.[3][4]

Gasoducto Centro Oeste is one of two pipelines – along with Gasoducto Norte Gas Pipeline – that comprise the Transportadora de Gas del Norte (TGN) system in northern and central Argentina. TGN's system is linked to other gas transportation networks in neighboring countries, such as central and northern Chile through the GasAndes, Gasoducto del Pacífico and NorAndino pipelines; to the south of Brazil through the Paraná-Uruguayana Gas Pipeline (Transportadora de Gas del Mercosur - TGM), and to Uruguay by means of the Entrerriano pipeline.

TGN is controlled by Gasinvest, a joint venture between Tecpetrol Internacional S.L. and CGC (Compañía General de Combustibles S.A). GasInvest holds a 56% stake in TGN, with the remaining shares divided between Southern Cone Energy Holding Co, Inc. (24%) and Bolsas y Mercados Argentinos S.A. (20%).[5][6]

In November 2018 a section of the pipeline located 6 km south of Puelén exploded.[9]
