West-East Gas Pipeline

From Wikipedia, the free encyclopedia

The West-East Gas Pipeline is a 4,000 kilometres (2,500 mi) long pipeline, which runs from Lunnan in Xinjiang to Shanghai. The pipeline pass through 66 counties in the 10 provinces in China.[1] Natural gas transported by the pipeline is used for electricity production in the Yangtze River Delta area. There is a plan to replace use of coal by gas in Shanghai by 2010.

[edit] History

The construction of the West-East Gas Pipeline started in 2002 and it was put into operation on 1 October 2004. The pipeline is owned and operated by the Natural Gas and Pipeline Company, subsidiary of PetroChina. Originally was agreed that PetroChina would have had 50% of the pipeline, while Royal Dutch Shell, Gazprom and ExxonMobil had been slated to hold 15% each and Sinopec 5%. However, in August 2006 this agreement was terminated by PetroChina.

[edit] Technical features

Capacity of the pipeline is 12 bcm natural gas annually.[2] The cost of pipeline was $5.7 billion. By the end of 2007 the capacity is planned to be upgraded up to 17 bcm. For this purpose 10 new gas compressor stations will be built and 8 existing stations will be upgraded.[3]

[edit] Connections

The West-East Gas Pipeline is connected to the Shaan-Jing Parallel Pipeline by the 886 kilometres (551 mi) long Ji-Ning branch between the Qingshan Distributing Station and the Anping Distributing Station, operational since 30 December 2005.

[edit] Source of supply

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

[edit] Second pipeline

 This article or section contains information about a planned or proposed pipeline.
It may contain information of a speculative nature and the content may change as the construction and/or completion of the pipeline approaches, and more information becomes available.

Construction of the second west-east gas pipeline started on 22 February 2008. The pipeline with the total length of 9,102 kilometres (5,656 mi), including 4,843 kilometres (3,009 mi) of main line and eight sub-lines, will run from Khorgos in northwestern Xinjiang to Guangzhou in Guangdong. Up to Gansu, it will be parallel and interconnected with the first west-east pipeline. The western part of the main line is expected to be commissioned by 2009 and the eastern part by June 2011. [4]

The capacity of the pipeline would be 30 bcm of natural gas per year. It will be mainly supplied by the Central Asia-China gas pipeline. The pipeline is expected to cost US$ 20 billion.[4][5] It will be developed by China National Oil and Gas Exploration and Development Corp. (CNODC), a joint venture of China National Petroleum Corporation and PetroChina.[6]
