Gasoducto del Pacifico, or Pacific Pipeline, is a natural gas pipeline running from the Loma la Lata gas field in Argentina to Talcahuano, Chile.[1][2][3]


Starting from the Loma la Lata gas field in Neuquén province, Argentina, the pipeline runs via San José de Añelo, Argentina[1] and Pemuco, Chile[4] to Talcahuano, Bío Bío region, Chile.[5][6]

Project Details

  • Owner: GNF (Gas Natural Fenosa), Enap, Trigas, YPF[7]
  • Current capacity: 229.6 MMcf/d (6.5 MMcm/d)[8]
  • Length: 670 km / 416 miles[4]
  • Status: Operating
  • Start Year: 1999[9]


Opened in November 1999, the 670-kilometer Gasoducto del Pacifico runs through Argentina (299 km[1]) and Chile (just over 370 km[4]). The pipeline supplies natural gas to industrial and residential customers in Chile's Biobío region.[4]

In 2005 a section of the pipeline between Argentina and Chile was shut down as the two countries chose to use their respective sections to meet their domestic need for gas, but in November 2018 the Chile-Argentina connection was reopened to transport gas from Argentina's Vaca Muerta field.[7]

In August 2020, a ruling by Chile's Supreme Court paved the way for gas imported through the proposed Talcahuano LNG Terminal to be transported via the Gasoducto del Pacífico network upon the terminal's completion in 2022.[10]

Expansion Project Details

  • Owner: in Chile: GNF (Gas Natural Fenosa) 60%, Enap % unknown, Trigas % unknown; in Argentina: GNF, 56.7%, Enap, Trigas & YPF, % unknown[7]
  • Capacity: 441.4 MMcf/d (12.5 MMcm/d)[7]
  • Length: 0
  • Status: Operating
  • Start Year: 2019

Proposed Expansion Background

In May 2018 the Spanish gas company Fenosa announced that it would invest US$50 million to increase the pipeline's capacity by 6.0 million cubic meters per day, to a total of 12.5 million cubic meters per day.[11] According to news reports in May 2019, the expansion project was already nearing completion,[12]and in July 2019 the new compression station at San José de Añelo (Neuquén province) began operating.[13]
