Facility Details

There are two main fields from which oil and gas are produced: West Mereenie and East Mereenie.

The fields produce from approximately 57 wells through approximately 80 kilometres of pipelines and flowlines via the Eastern Satellite Station (ESS) and the Central Treatment Plant (CTP).

Associated gas from oil produced at the ESS is compressed and reinjected into the main oil reservoir to maintain reservoir pressure while gas from the CTP is currently reinjected.

Oil and condensate is loaded onto trucks for shipment to Port Bonython and sale to customers.

The central processing plant comprises:

• Oil processing: crude/water separation, condensate stabilisation, crude/condensate storage and crude loading facilities.
• Gas processing: field compression, inlet slugcatchers, gas dehydration and separation, a natural gas liquids recovery plant, associated gas compression for reinjection and pipeline compression.

Water is provided by bores and a membrane treatment plant and electricity is provided by onsite generation. The plant is serviced by an airstrip.
