Key highlights

  • Carnarvon’s 9 October 2026 quarterly said the Transocean Equinox is contracted for the 2027 Bedout campaign, with drilling expected from April 2027.
  • The Ara prospect has a 37% geological chance of success and 191 mmboe of prospective resources (gross, unrisked Pmean).
  • Cash was about A$97 million with no debt, and the campaign is expected to cost the company less than A$20 million if two wells are drilled.

Carnarvon Energy Ltd (ASX:CVN) was trading at $0.10 on 21 October 2026, unchanged at 0.00% in the session.

Brent Crude gained 0.60% to US$109.48, with persistent Middle East tensions involving Iran, Saudi Arabia and the Houthis in Yemen continuing, and a reported draw in US oil inventories added to the picture of tightening supply. Carnarvon Energy is an Australian oil and gas explorer with interests in the Bedout Sub-basin offshore Western Australia, including the Dorado oil project.

What Carnarvon Energy does

Carnarvon Energy Limited is an ASX-listed oil and gas company with interests in the Bedout Sub-basin offshore Western Australia, where Santos is the operator. Its interests in the WA-435, 436, 437 and 438-P permits range from 10% to 20%. The company has a development carry of US$90 million for the Dorado project and holds a 19.9% stake in Strike Energy Ltd (ASX:STX).

Quarterly activities report

In its quarterly activities report for the period ended 30 September 2026, dated 9 October 2026, Carnarvon said the Transocean Equinox semi-submersible has been contracted for the 2027 Bedout drilling campaign, with environmental plan approval on track for drilling to start from April 2027, a date chosen to largely avoid the main cyclone season. The campaign includes one firm well and one contingent well in Carnarvon’s permits, and the contingent well is expected to be firmed up in the coming quarter in line with joint venture budgeting and approvals.

The company reported cash of about A$97 million, no Debt and a US$90 million development carry for Dorado. If both wells are drilled, the expected cost to Carnarvon is about A$20 million, to be funded from cash.

The Ara prospect

Ara, the most likely firm well, is a prospect in the north of WA-435-P, where Carnarvon holds 10%. It lies about 80 km north of the Dorado field and would test a new play fairway. Ara has dual objectives: a stratigraphic pinch-out trap in the Archer Formation, comparable in age to the Dorado reservoir, and a secondary target in the Late Triassic Cuvier Member. The company estimates a 37% geological chance of success and prospective resources of 191 mmboe, gross unrisked Pmean. It noted that fluid type cannot be reliably determined before drilling, so Ara may contain oil, gas or both.

The company stated that exploration in the Bedout Sub-basin has had a success rate of about 67% since modern 3D seismic was applied, with four discoveries.

Dorado

Dorado remains FEED-ready, and pre-FEED work completed in 2024 indicated a plateau rate of approximately 60,000 barrels of oil per day. The company cited industry data published in September 2026 showing Australia’s Crude Oil production fell to around 32,000 bopd in the June 2026 quarter. It also noted that its Strike Energy holding is linked to a recently announced West Erregulla pathway.

Sector context

Offshore exploration campaigns depend on rig availability, environmental approvals and weather windows. During the session, Brent crude was at US$109.48 per barrel, up 0.60%, and the S&P/ASX 200 Energy index was at 11,167.20 amid Middle East tensions and a reported draw in US oil inventories. Carnarvon’s report also refers to domestic energy security discussions in Australia.

Risks and uncertainties

Ara is an exploration prospect with a 37% geological chance of success, so there is a 63% chance that it will not result in a discovery on the company’s own estimate. Prospective resources relate to undiscovered accumulations and carry discovery and development risk. The contingent well has not been firmed up, the environmental plan is still to be approved and the program depends on joint venture approvals, so schedule and budget could change. Dorado has no sanctioned development, and funding for it would be needed beyond the US$90 million carry.

Catalysts to watch

Items referenced include firming up of the contingent well in the coming quarter, environmental plan approvals, the start of drilling from April 2027, results of Ara and any decision on Dorado development.
