BG begins coal-seam gas commissioning for QCLNG project
BG Group has started commissioning its Surat basin coal-seam gas processing network that will send supplies of gas to the company’s Queensland Curtis LNG (QCLNG) project.
A total of 17 field compressor stations and four central processing plants at three Surat basin hubs at Chinchilla, Wandoan, and Dalby make up the gas gathering and supply system.
One of the key central facilities, named the Ruby Jo processing plant, has a nameplate processing capacity of 440 MMcfd of gas. The other three plants are similar, and the system will transport gas through a 540-km buried pipeline to the QCLNG plant near Gladstone.
The central processing plants and field compression stations have been constructed during the last 2½ years by 1,500 engineers, civil works contractors, mechanics, welders, electricians, and others.
Gas will enter the system at the significant pressure of 10,000 kPa.
The $20.4 billion project is due to come on stream and start exports of LNG in December. When fully on stream the project will produce 8.5 million tonnes/year of LNG.
BG says the project is still open to securing more third-party gas to feed into the pipelines.
