PetroChina Pipelines

PetroChina Pipelines, a subsidiary of PetroChina holding a 72.26% stake, is primarily responsible for the operation and management of the first three phases of the West–East Gas Pipeline Project—one of China’s most significant energy infrastructure initiatives.

West–East Gas Pipeline I

History

Construction of the first West–East Gas Pipeline began in 2002, with trial operations launching on October 1, 2004, and full commercial operations commencing on January 1, 2005. Initially, PetroChina partnered with Royal Dutch Shell, Gazprom, ExxonMobil, and Sinopec, holding 50%, 15%, 15%, 15%, and 5% shares respectively. However, in August 2004, the joint venture was dissolved after negotiations failed, leaving PetroChina as the sole operator.

Technical Features

The 4,000-kilometer (2,500 mi) pipeline extends from Lunnan in Xinjiang to Shanghai, passing through 66 cities across 10 provinces. It delivers 12 billion cubic meters (420 billion cubic feet) of natural gas annually to power plants in the Yangtze River Delta. The project cost approximately US$5.7 billion, with plans to expand capacity to 17 billion cubic meters (600 billion cubic feet) through additional compressor stations and upgrades by late 2007.

Connections

The main pipeline links to the Shaan–Jing pipeline via three branch lines, including the Ji-Ning branch, an 886-kilometer (551 mi) extension that became operational on December 30, 2005.

Source of Supply

Gas is primarily sourced from the Tarim Basin in Xinjiang and the Changqing gas fields in Shaanxi. From 2009, coalbed methane from the Qinshui Basin in Shanxi was also added to the supply network.

West–East Gas Pipeline II

Construction and Features

Construction began on February 22, 2008, covering a total of 9,102 kilometers (5,656 mi)—including a 4,843-kilometer (3,009 mi) mainline and eight sub-lines. It runs from Khorgas in Xinjiang to Guangzhou in Guangdong Province. The western segment was commissioned in 2009, with the eastern section completed in June 2011.

The pipeline’s annual capacity is 30 billion cubic meters (1.1 trillion cubic feet), mainly fed by the Central Asia–China Gas Pipeline. With an estimated cost of US$20 billion, the project was led by China National Oil and Gas Exploration and Development Corporation (CNODC), a joint venture between CNPC and PetroChina.

West–East Gas Pipeline III

Construction and Features

Work on the third pipeline began in October 2012 and was completed in 2015. Spanning 7,378 kilometers (4,584 mi), including 5,220 kilometers (3,240 mi) of trunkline and eight branches, it runs from Horgos (Xinjiang) to Fuzhou (Fujian), crossing major provinces such as Gansu, Ningxia, Shaanxi, Henan, Hubei, Hunan, Jiangxi, Fujian, and Guangdong.

The system includes three gas storage facilities and an LNG plant, capable of transporting 30 billion cubic meters (1.1 trillion cubic feet) annually at operating pressures between 10–12 megapascals (1,500–1,700 psi). It is supplied through the Central Asia–China Gas Pipeline’s Line C, with additional inputs from the Tarim Basin and coalbed methane sources in Xinjiang. Rolls-Royce supplied the compressors for this project.

Controversies

Chemical Spills

2005 Jilin Chemical Plant Explosion

In November 2005, a PetroChina chemical plant in Jilin exploded, releasing 100 tons of benzene into the Songhua River. The 80-kilometer-long toxic slick contaminated the water supply of Harbin, leaving nearly 4 million residents without water for five days. The spill reached Khabarovsk, Russia, where authorities struggled to ensure water safety. PetroChina was fined 1 million yuan, the maximum penalty under Chinese law. Cleanup costs were estimated at US$1 billion, and China’s Foreign Minister Li Zhaoxing publicly apologized to Russia.

2014 Lanzhou Petrochemical Leaks

In 2014, Lanzhou Petrochemical, a PetroChina subsidiary, was found responsible for benzene contamination, ethylene leaks, and air pollution in Lanzhou. The local government demanded an apology and strict remediation after public outcry.

Environmental and Public Protests

Tarim Basin Environmental Concerns

The “Western Gas to the East” project in the Tarim Basin raised ecological concerns over the impact of gas extraction on fragile desert ecosystems.

Chengdu Plant Demonstration (2008)

In 2008, residents of Chengdu protested against the construction of a US$5.5 billion petrochemical complex, fearing pollution despite PetroChina’s claim that US$565 million was allocated to environmental protection. Peaceful demonstrations occurred on May 3–4, with minimal government interference.

Trade Anomalies

In January 2022, PetroChina Fuel Oil Co. Ltd. was penalized by the National Development and Reform Commission (NDRC) for oil trading irregularities that distorted market competition, enabled excessive refinery expansion, and reduced government tax revenues.

Human Rights Allegations

In 2011, EarthRights International accused PetroChina of complicity in forced labor practices in Myanmar (Burma), linking the company to human rights violations tied to regional energy projects.

Corruption Cases

Jiang Jiemin Investigation (2013–2015)

Former PetroChina chairman Jiang Jiemin and several executives were investigated for corruption and abuse of power in 2013. Jiang, an ally of former security chief Zhou Yongkang, was convicted in 2015 of bribery, power abuse, and illicit asset possession, receiving a 16-year prison sentence.

Liao Yongyuan’s Sentence (2017)

In January 2017, ex–vice chairman Liao Yongyuan was sentenced to 15 years in prison for abuse of power and accepting nearly US$2 million in bribes.

Ling Xiao Investigation (2021)

In October 2021, the Central Commission for Discipline Inspection announced an investigation into former PetroChina vice president Ling Xiao for “serious disciplinary violations.”

Tax Evasion Allegations

In January 2014, the International Consortium of Investigative Journalists (ICIJ) released documents from the British Virgin Islands, implicating CNPC, PetroChina, Sinopec, and CNOOC in alleged offshore tax evasion schemes.

Global Ranking and Recognition

According to the Forbes Global 2000 rankings:

• 2018: PetroChina ranked 30th among the world’s top listed companies.
• 2019: Improved to 22nd place.
• 2023: Climbed further to 18th, reaffirming its position as one of the largest publicly traded energy companies globally.

Corporate Bonds

On October 24, 2008, PetroChina launched a massive medium-term corporate bond issuance valued at 80 billion yuan (around $11.7 billion). This issuance became the largest domestic bond offering ever made by a publicly listed company in China, reflecting the firm’s strong financial standing and investor confidence.

Logo

Since 2004, PetroChina’s logo has symbolized the company’s vision, energy, and national identity. The emblem features a rising sun emerging from a flower-like structure composed of red and yellow petals—colors deeply rooted in Chinese tradition and symbolism. Beneath the design, the word “PetroChina” appears in bold black lettering, emphasizing strength and stability.
