Producing basins

All past and current onshore gas and oil production in the Northern Territory is from conventional fields in the Neoproterozoic to Late Devonian-Early Carboniferous Amadeus Basin.

The Amadeus Basin covers approximately 170,000 km2 in area in the Northern Territory and extending into Western Australia.

Petroleum systems

There are up to five conventional petroleum systems present in the Amadeus Basin, including the Ordovician system that hosts the Mereenie and Palm Valley fields that have been in production since 1983. This petroleum system also hosts the Surprise oil field that was in production in 2014 and 2015 and the Dingo gas field which commenced production in 2015.

Three of the other four petroleum systems are Neoproterozoic in age and the fourth is Neoproterozoic to Cambrian. A variety of structural and stratigraphic traps are present within the basin.

Production

Total production from the basin to the end of 2019 is 440 billion standard cubic feet (bscf) of gas and 18.5 million barrels of oil.

In 2019, 18.293 bscf of gas was produced from these fields comprising 14.150 bscf from Mereenie, 0.305 bscf from Palm Valley and 0.110 bscf from Dingo. 0.212 million barrels of oil was produced from the Mereenie field in 2019. These fields are operated by Central Petroleum Ltd. Annual updated production figures for the Mereenie, Palm Valley, Dingo and Surprise fields can be found on the Department of Primary Industry and Resources website

Geological and exploration data and reports

The eastern and northern sections of the Amadeus Basin are well covered by seismic including limited 3D seismic and over 100 petroleum wells.

A more detailed description of the geological potential of the Amadeus Basin can be found in Northern Territory Geological Survey (NTGS) Report 22.

Open file petroleum company reports and all NTGS data and information on Amadeus Basin is available from the GEMIS website.
