Gasoducto Sistema Cordillerano-Patagónico, also known as Gasoducto Cordillerano, is a gas pipeline system in Argentina.[1]


The pipeline system is in northern Argentina.

Project Details

  • Owner: Pampa Energía S.A.
  • Capacity:
  • Length: 133.7 km / 83 miles
  • Status: Operating
  • Start Year: 2019


Operated by TGS (Transportadora Gas del Sur, controlled by Buenos Aires-based Pampa Energia), the pipeline supplies natural gas to 25 population centers in the provinces of Neuquén, Rio Negro and Chubut. However, due to the sustained growth in the demand for natural gas distribution service through networks, this system is operating at full capacity, so it does not currently have availability for the incorporation of new consumption without the execution of these infrastructure works.[2]

An expansion of the Cordillera-Patagonia gas pipeline was announced in 2017. The objective of the project is to expand capacity of the system to meet the demand generated by 22,000 additional users in different locations in its layout in addition to the new industrial parks that are now in the final phase of construction. The project is expected to cost $100 million with an estimated execution time of 18 months. The work consists of installing a compressor station in the town of Río Senger with a capacity of 3,000 hp, along with several new sections of pipeline, as follows[2][3]:

  • 5.5 miles (9 km) of 16-inch pipeline
  • 39 miles (62.7 km) of 12-inch pipeline
  • 16 miles (26 km) of 10-inch pipeline
  • 2.2 miles (3.5 km) of 8-inch pipeline
  • 20.2 miles (32.5 km) of 6-inch pipeline

In June 2017, Argentina's Ministry of Energy awarded construction contracts to three firms: Siat, Siderca and Royo. The 22,000 new users to be served by the pipeline expansion would be in the provinces of Chubut, Río Negro y Neuquén. Communities targeted for the expansion in Chubut province include Esquel, Trevelin, Lago Puelo, Epuyén and Gobernador Costa.[4]

In July 2018, amid rumors that the pipeline expansion had been halted, Gustavo Menna, a national deputy from Chubut province, asserted that construction work had been proceeding steadily since November 2, 2017, and that the pipeline expansion was 48% complete.[5]

At a January 2019 ceremony in Bariloche (Río Negro province), Argentine president Mauricio Macri inaugurated the first stage of the pipeline expansion.[6] According to Argentina's energy agency IEASA, the new infrastructure comprised 141 km of new pipes in 13 loops expected to serve 10,000 households, with an additional 12,000 households to be connected upon completion of construction at the Río Senger compressor station.[7] News reports indicated that seven of the expansion project's nine sections were operational as of January 2019, with two still awaiting completion.[3]

Two injection points feed the pipeline; the first, at Collón Curá, uses gas from Plaza Huincul, while the other, near Esquel, uses gas from the Golfo de San Jorge.[8]

In July 2019, an accident involving a heavy equipment operator damaged the pipeline near Plaza Huincul, but TGS work crews were able to repair it and restore service within 18 hours.[9]
