The Northern Territory (NT) government has launched the EPNT26-1 licensing round, offering 50 exploration assets for competitive bidding. This release includes areas within the Beetaloo sub-basin, a globally significant shale gas prospect within the greater McArthur basin.

Significance and Resource Potential of the Beetaloo

The Beetaloo sub-basin is considered one of the world's largest shale gas plays, with industry estimates indicating over 500 trillion cubic feet of discovered and prospective resources. Its potential production capacity could rival major plays like the Marcellus shale in the US, possibly exceeding 6000 terajoules per day.

Geological and Technical Basis

The area is deemed highly prospective due to proven unconventional petroleum systems. This assessment is supported by extensive subsurface data, including 37 wells and over 9000 kilometres of seismic data. The geology features Palaeoproterozoic to Mesoproterozoic sedimentary successions, with key organic-rich shales in the Velkerri and Kyalla formations. Drilling and testing have confirmed working petroleum systems with significant gas rates and stable production. The overlying Neoproterozoic Kiana group also holds unproven petroleum potential.

Strategic Context and Development

The acreage release aims to drive investment and develop a critical gas resource to support domestic energy security. The offered blocks are surrounded by existing high-quality shale gas acreage held by major companies. Nearby developments, such as Beetaloo's EP 98 expected to produce gas by mid-2026, Tamboran's Shenandoah South pilot project, and Santos's planned drilling campaign, highlight the basin's active advancement.

Promotion and Application Process

The opportunity was recently promoted at the North American Prospect Expo in Houston to attract international investment from key shale gas markets. Applications for the 50 areas are now invited, with a submission deadline of 31 July.
