The facility accepts production from approximately 45 gas fields containing about 130 producing gas wells through approximately 450 kilometres of pipelines and flowlines.
All field boost compression is located at the plant. Further nodal compression is operational at Yanda, Challum and Munkah/Wackett. The Ballera facility also incorporates the Chookoo storage facility that is used for the storage and processing of sales gas at the Chookoo field.
Sales gas is sent to Mt Isa via an 800 kilometre pipeline. The remaining gas, natural gas liquids and condensate are sent to Moomba via the 180 kilometre Ballera-Moomba pipeline. No crude oil is processed at Ballera. All oil is sent to the Jackson facility 65 kilometres to the south-east.
The central processing plant comprises:
- inlet separators
- a potassium carbonate CO2 removal train
- glycol gas dehydration
- a Dew Point Control separation train
- export compression.
Water is provided from local bores and is purified through a membrane treatment plant. 45 MW electricity generation capacity is on site. The plant is serviced by a jet-capable sealed airstrip.
