Facility Details

High pressure gas is produced from the Dingo wells and transported via pipeline the Dingo Processing facility at Brewer Estate near Alice Springs where the water and hydrocarbon condensates are removed.  The pressure is dropped during the conditioning process to meet customer requirements.

Description and Geology

Gas was discovered in 1985 in the Neoproterozoic lower Arumbera Sandstone. The structure is 11 km by 5.6 km, and the productive reservoir is at a depth of approximately 3,000 metres subsurface.


The Dingo Gas Field Development, completed in April 2015, comprised the construction of wellhead facilities, gathering pipelines, gas conditioning facilities, a 50 km gas pipeline (Pipeline Licence PL 30) to Brewer Estate in Alice Springs, compression and custody transfer metering facilities.  It was designed to service a gas sale contract with Territory Generation.

Appraisal and Development

With the commissioning of the Dingo Gas Field and Pipeline culminating in the granting of the Consent to Operate, the Dingo Gas Sales Agreement became unconditional with commencement starting 1 April 2015.

Additional wells may be required to increase rates and service additional gas sales contracts.


As part of arrangements in the purchase of Central’s interest in Mereenie Oil and Gas Field, Central has acquired 100% interest and Operatorship of 20 graticular blocks excised from the Joint Venture with Santos in EP 82 surrounding the Dingo Gas Field .  This area of 1,492 km2, referred to as EP 82DSA (Dingo Satellite Area), contains several leads identified on the existing sparse seismic grid as well as the currently sub-commercial Orange Gas Field which was discovered in 1966 and is 19 km by 8 km in area.

Due to the proximity to the Dingo Gas Field and associated infrastructure, these satellite prospects are very attractive to Central as they could provide incremental reserves in the event of drilling success. Additional seismic is required to delineate these leads, which are currently estimated to be of a similar size to the Dingo Gas Field.

Further gas potential resides in other reservoirs within the Dingo Gas Field and EP 82DSA. The deeper Pioneer Sandstone which flowed gas at Ooraminna Gas Field or the shallower Pacoota Sandstone, which are productive at Mereenie and Palm Valley Fields but water wet at Dingo, may be prospective in satellite prospects as well as the elongate Waterhouse Anticline.


Central believes data gathered during production will materially increase the resources in the field, leading to the opportunity to capture additional sales contracts. Exploration opportunities beneath Dingo Gas Field or in satellite structures as well as at undrilled deeper reservoir levels in the Waterhouse Anticline have the potential to add significant reserves and value by levering off the infrastructure now owned by Central.
