Carnarvon Energy has contracted the Transocean Equinox semi-submersible rig for an exploration drilling campaign in Australia’s Bedout Sub-basin, with operations set to begin from April 2027. The program targets one firm well and one contingent well across Carnarvon’s exploration permits, with total costs to the company estimated at approximately A$20 million if both wells are drilled.
Rig Contract Signed for April 2027 Drilling Start
Carnarvon Energy selected the Transocean Equinox following a comprehensive bid evaluation process that got underway in early 2025. The semi-submersible mobile offshore drilling unit will support a multi-well campaign spanning Carnarvon’s Bedout Sub-basin exploration permits.
Operations are scheduled to commence from April 2027, covering one firm well and one contingent well. CEO Philip Huizenga described the contract signing as “the critical step for the Company to return to drilling in 2027,” calling it a significant milestone toward more regular drilling activity.
Why the Bedout Sub-basin Is Being Targeted
The 2027 campaign has a defined objective: establish the scale of the Bedout Sub-basin’s resource potential. Carnarvon plans to target some of the largest prospects in its exploration portfolio — Ara, Yuma, Goats Eye, and Hutton — each identified through the Bedout MegaMerge 3D seismic survey. The program will also pursue a northern extension of previous discoveries and test play-types that have not been evaluated before in the basin.
Carnarvon points to a 67% success rate when drilling using high-quality 3D seismic data. That figure shapes how the company approaches prospect selection across the Bedout.
Expected Costs and Funding Arrangements
If both wells are drilled, Carnarvon’s total expected cost comes to approximately A$20 million — its share under the joint venture structure. The company held a cash balance of A$98 million as of March 31, 2026, and intends to fund the campaign directly from that balance.
No external financing or equity raise is required. For a smaller explorer, that matters. Offshore drilling programs can place real pressure on company balance sheets, and the ability to proceed without diluting shareholders or taking on debt is a meaningful structural advantage.
Background: Carnarvon’s Bedout Exploration History and Joint Venture
The Transocean Equinox is not sitting idle ahead of 2027. It is currently completing a multi-well exploration program off Victoria’s coast — work expected to wrap up by early 2027 — before transitioning directly to the Bedout campaign.
Santos serves as Joint Venture Operator alongside Carnarvon, bringing operational experience to what the company describes as a high-impact program. The Bedout Sub-basin has a prior record of exploration discoveries, establishing it as a recognized frontier in Australian offshore waters. The 2027 campaign builds on that earlier work and the extensive data gathered through the MegaMerge survey, marking Carnarvon’s return to more active drilling in the region.
Huizenga noted the company looks forward to working closely with both Transocean and Santos “to ensure we deliver positive results in a safe and efficient manner.”
A$20 Million for Two Wells
Carnarvon Energy has secured the Transocean Equinox for a Bedout Sub-basin exploration campaign beginning April 2027. The program includes one firm well and one contingent well, with a combined cost to Carnarvon of approximately A$20 million if both are drilled.
The shortlisted prospects — Ara, Yuma, Goats Eye, and Hutton — are all defined on the Bedout MegaMerge 3D seismic survey, with the campaign also targeting a northern extension of prior discoveries and new play-types not previously tested in the basin. Carnarvon will fund the program from its existing A$98 million cash balance, with no external financing needed. Santos acts as Joint Venture Operator, and the Transocean Equinox is expected to arrive from its Victoria work program in early 2027.
