Guaymas-El Oro Pipeline

From Global Energy Monitor


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

The Guaymas-El Oro Pipeline is an operating natural gas pipeline running between Sonora and Sinaloa states, Mexico. Together with the adjoining Sásabe-Guaymas Gas Pipeline, it is also known as the Sonora pipeline or Gasoducto Sonora, Phase II.[1][2]


The pipeline runs from Guaymas, Sonora to El Oro, Sinaloa, Mexico.

Project Details

  • Operator: IEnova[3]
  • Parent Company: Sempra Energy[3]
  • Current capacity: 5.3 billion cubic meters per year[3][4]
  • Length: 206 miles / 331 km[4]
  • Status: Idle[5]
  • Start Year: 2017[3][4]


In October 2012, the Mexican division of Sempra International signed a 25-year contract with Mexico's Comisión Federal de Electricidad to build, own, and operate the Guaymas-El Oro project.[6] The pipeline, whose construction was completed in May 2017[4][7], interconnects with the El Oro-Mazatlan Pipeline[8] and is a key component of Mexico's north-northwest natural gas delivery network.[9] The pipeline was shut down in August 2017 following an act of sabotage by indigenous Yaqui groups who oppose its operation, and as of September 2019 it remained offline pending reconstruction of a missing 10-kilometer segment.[5]

Technical description

The pipeline, operated by IEnova (Infraestructura Energética Nova SAB de CV), is 330 km (205 mi) long and 30 inches in diameter, with a capacity of 510 million cubic feet per day[3][4], or 5.3 billion cubic meters of natural gas per year.


The Guaymas-El Oro project has generated opposition from an indigenous Yaqui group in Loma de Bácum, Sonora state, whose members say they never agreed to construction of a nine-mile section of pipeline that crosses their land. In an August 2017 protest, members of the community used a backhoe to remove a 25-foot section of the pipeline, disrupting operations and perpetuating an ongoing legal battle with IEnova.[10][11][12] As of March 2018, the pipeline's status remained in limbo pending a decision by a Mexican federal district court.[7]

In 2019, Mexico's federal electricity commission CFE agreed to work with IEnova to reopen the blocked section of pipeline[13][14][15], and in September 2019 the government announced that it was negotiating an agreement with the Yaqui community to reroute the pipeline south to steer clear of Loma de Bácum and other Yaqui-owned lands.[5] In an August 2020 meeting with Yaqui leaders, Mexican president Andrés Manuel López Obrador confirmed the government's support for rerouting the pipeline as a means of resolving the conflict.[16]
