Project Details

• Operator: PetroChina West–East Gas Pipeline Company
• Parent Company: China National Petroleum Corporation
• Current Capacity: 17 billion cubic meters per year
• Length: 2,485 miles / 4,000 kilometers
• Diameter: 1016 mm
• Status: Operating
• Start Year: 2005
• Finance: 140000 million RMB

Background

The construction of the West–East Gas Pipeline started in 2002. The pipeline was put into trial operation on 1 October 2004, and the full commercial supply of natural gas commenced on 1 January 2005. The pipeline is owned and operated by PetroChina West–East Gas Pipeline Company, a subsidiary of PetroChina. Originally, it was agreed that PetroChina would have owned 50% of the pipeline, while Royal Dutch Shell, Gazprom, and ExxonMobil had been slated to hold 15% each, and Sinopec 5%. However, in August 2004, the Board of Directors of PetroChina announced that following good faith discussions with all parties to the Joint Venture Framework Agreement, the parties had not been able to reach an agreement, and the joint venture framework agreement was terminated.

Technical features

The 4,000-km (2,485-mi) pipeline runs from Lunnan in Xinjiang to Shanghai. The pipeline passes through 66 cities in 10 provinces. Natural gas transported by the pipeline is used for electricity production in the Yangtze River Delta area. There is a plan to replace coal with gas in Shanghai by 2010. The capacity of the pipeline was originally 12 billion cubic meters of natural gas annually. The cost of the pipeline was US$5.7 billion. By the end of 2007, the capacity was planned to be upgraded to 17 billion cubic meters. For this purpose, ten new gas compressor stations will be built and eight existing stations are to be upgraded.

Connections

The West–East Gas Pipeline is connected to the Shaan-Jing pipeline by three branch pipelines. The 886-km (551-mi) Ji-Ning branch between the Qingshan Distributing Station and the Anping County Distributing Station became operational on 30 December 2005.

Source of supply

The pipeline is supplied from the Tarim Basin gas fields in Xinjiang province. The Changqing gas field in Shaanxi province is a secondary gas source. In the future, the planned Kazakhstan-China gas pipeline will be connected to the West–East Gas Pipeline.

Starting from 15 September 2009, the pipeline is also supplied with coalbed methane from the Qinshui Basin in Shanxi.
