Amadeus

Commentary

The Amadeus Basin benefits from a supportive Northern Territory regime and existing gas infrastructure. Federal approvals have become more supportive, but foreign-ownership rules, gas reservation and price caps, and safeguard-mechanism costs continue to weigh on longer-term investment.

Location

Description

The AAB occupies much of the southern quarter of the Northern Territory and extends about 150km into Western Australia, covering about 170,000sq km in total. It has a maximum sediment thickness of 14,000m with several major depocentres, which create a series of identifiable sub-basins and. Early Neoproterozoic volcanics and fluvial siliciclastics in the west form a rift sequence associated with an extensional event caused by the breakup of the Rodinia Supercontinent.

Summary

Despite a long exploration history, the Basin remains underexplored with only a handful of wells, as it has been overshadowed by the more prolific Eronamaga and Surat basins.
