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


The northern "Cordillerano" section of the pipeline system runs from Plaza Huincul (Neuquén province) to Esquel (Chubut province), Argentina. The southern "Patagónico" section of the pipeline runs from Esquel to Comodoro Rivadavia, Chubut province, Argentina.

Project Details

  • Owner: Pampa Energía S.A.[2]
  • Capacity:
    • Cordillerano Pipeline: 1.327 MMcm/d / 47 MMcf/d[3]
    • Patagónico Pipeline: 1 MMcm/d / 35 MMcf/d[4]
  • Length:
    • Cordillerano Pipeline: 563 km / 350 miles
    • Patagónico Pipeline: 600 km / 373 miles[4]
  • Status: Operating
  • Start Year:
    • Cordillerano Pipeline: 1986[5]
    • Patagónico Pipeline: 2006[4][6]


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.

The original pipeline was built in two sections, which intersect in Esquel, Chubut province, Argentina.[4]

Construction of the initial 339-kilometer section of the Cordillerano Pipeline between Plaza Huincul, Bariloche and San Martín de los Andes began in 1984[3] and was completed in 1986.[5] The pipeline was subsequently extended to Esquel, providing service to several communities in Río Negro and Chubut provinces. By 2004, the pipeline's capacity had increased to 1.327 MMcm/d.[3]

Construction of the southern Patagónico Pipeline was completed in 2006, adding 600 kilometers to the system with another 1 million cubic meters of capacity.[4][6]

Expansion Project Details

  • Owner: Pampa Energía S.A.
  • Capacity: 673,000 cubic meters per day / 24 MMcfd[7]
  • Length: 133.7 km / 83 miles
  • Status: Operating
  • Start Year: 2019

Expansion Project

An expansion of the Cordillera-Patagonia gas pipeline was announced in 2014, due to sustained growth in demand for natural gas and insufficient capacity of the current pipeline.[8][9] The project's stated objective was to expand capacity of the system to meet the demand generated by 22,000 additional users and new industrial parks under construction at the time. The project was expected to cost $100 million with an estimated execution time of 18 months. The proposed expansion included installation of 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[8][10]:

  • 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.[11]

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.[12]

At a January 2019 ceremony in Bariloche (Río Negro province), Argentine president Mauricio Macri inaugurated the first stage of the pipeline expansion.[13] 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.[14] News reports indicated that seven of the expansion project's nine sections were operational as of January 2019, with two still awaiting completion.[10]

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.[7]

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.[15]
