Australia - Bonaparte Gulf

Turtle  & Barnett 

Melbana has a 100% interest in two contiguous permits WA-544-P and NT/P87, covering an area of almost 4,000km2 in the Petrel sub-basin – a shallow water area of the Timor Sea south west of Darwin off the northern coast of Australia.

These two permits, awarded to Melbana in November 2020, contain the undeveloped Turtle and Barnett oil discoveries and are adjacent to Melbana’s recently sold permit WA-488-P**.  The initial three-year term will look to leverage learnings from the Beehive project by reprocessing available 2D and 3D seismic data to determine whether the above discoveries can be upgraded and if the potential for deeper carbonate plays exist.



WA-488-P contains the giant Beehive prospect with its Prospective Resource of up to 1.4 billion barrels of oil. * The giant Beehive prospect, located in ~40m water depth, is one of the largest undrilled hydrocarbon prospects in Australia. It is a 180km2 isolated carbonate build up of Carboniferous age with 400m of mapped vertical relief and a crest at 4,100m. Beehive is analogous to the giant Tengiz field in the Caspian basin which is also a Carboniferous isolated carbonate build-up.

Beehive is located near to ENI’s producing Blacktip gas field and is covered by a high-quality 3D seismic survey acquired in 2018.

On 23 April 2021, Melbana announced that it had entered into a conditional sale and purchase agreement to sell its 100% interest in permit WA-488-P to a subsidiary of EOG Resources, Inc.


* Independent Expert McDaniel & Associates Consultants Competent Persons Report (30 June 2018) has estimated Beehive to have a prospective resource of 388 million barrels of oil equivalent (best estimate).  Melbana increased the best estimate prospective resource to 416 million barrels in 2020 following completion of a revised volumetric analysis using the 3D data.
