Carnarvon sharpens focus on Ara ahead of 2027 Bedout drilling

Ara emerges as Carnarvon’s lead 2027 drilling target

Carnarvon Energy Limited (ASX:CVN) is taking its next major exploration shot at Ara, a prospect 80 kilometres north of the Dorado field that the company expects to drill as the firm well in its 2027 Bedout campaign. Transocean Equinox has been contracted for the program, which is scheduled to begin from April next year, subject to environmental approvals and joint venture planning.

The campaign is currently structured around one firm well and one contingent well across Carnarvon’s Bedout permits. Environmental plans remain on track for approval before drilling, while the contingent well is expected to be confirmed during the December quarter through the budgeting and approvals process. The two-well program would cost Carnarvon approximately A$20 million.

Ara is a substantial but high-risk exploration proposition. Carnarvon assigns it a 37% geological chance of success and 191 million barrels of oil equivalent in gross, unrisked Pmean prospective resources. Those are estimates for an undiscovered accumulation, not discovered reserves, and the company says the prospect could contain oil and/or gas because fluid type cannot be reliably determined before drilling. The well has dual objectives, including an Archer Formation target comparable in reservoir age to Dorado and a deeper Cuvier Member target analogous to the Mungaroo Formation.

Contracted rig keeps the exploration timetable intact

The latest update reinforces the significance of the Transocean Equinox contract, previously announced for a 2027 campaign targeting one firm and one contingent well. Carnarvon says the multi-well, multi-year environmental plans give the joint venture flexibility to adjust targets as planning and approvals progress. The April start has also been selected to largely avoid Western Australia’s main cyclone season.

The geological case rests partly on the Bedout Sub-basin’s record on modern 3D seismic: four discoveries from six wells, or an approximate 67% success rate. That historical result provides useful basin context, but it does not determine Ara’s outcome. Success at either Ara objective would be play-opening for the northern acreage; failure, or an uneconomic discovery, would leave the prospective resource estimates without a demonstrated development pathway.

Dorado remains strategically important but timing is unresolved

Dorado remains FEED-ready and is being positioned by Carnarvon as a potential Australian oil-supply project. Pre-FEED work completed in 2024 indicated a possible liquids plateau of approximately 60,000 barrels per day, while the Dorado and surrounding fields are estimated to contain gross 2C resources of 249 million barrels of light oil and condensate plus 1.1 trillion cubic feet of gas.

The proposed first phase would use a wellhead platform tied back to an FPSO, with up to 12 wells and potential future tiebacks such as Pavo. Carnarvon estimates its net upfront capital expenditure at below approximately US$200 million, including a US$90 million development carry. However, development work is only expected to recommence in line with the operator’s evaluation of further Bedout resources, and the timing remains under discussion with the joint venture.

Cash position supports exploration spending

Carnarvon ended the September quarter with A$97.038 million in cash and cash equivalents, down from A$97.678 million three months earlier. It has no debt, while interest received during the quarter was A$1.283 million. Exploration and evaluation payments totalled A$531,000, staff costs were A$467,000 and administration and corporate costs were A$790,000.

On the quarter’s reported cash movements, Carnarvon recorded net operating inflow of A$26,000, investing outflow of A$533,000 and financing outflow of A$53,000, with an additional A$80,000 exchange-rate impact. The company forecasts A$900,000 to A$1.2 million of Bedout exploration expenditure and A$500,000 to A$800,000 in corporate and other costs for the December quarter. That leaves the immediate funding question relatively contained; the larger uncertainty is whether exploration spending eventually converts Ara’s prospective resources into a commercial discovery and whether Dorado moves beyond its FEED-ready status.
