Carnarvon Energy has contracted the Transocean Equinox semi-submersible drilling rig for a multi-well exploration campaign in Australia’s Bedout Sub-basin. The campaign, set to begin in April 2027, will target some of the largest prospects in Carnarvon’s exploration portfolio — with joint venture operator Santos also involved in the effort.
Carnarvon Energy contracts Transocean Equinox for 2027 Bedout drilling
The formal contract covers a multi-well campaign within Carnarvon’s Bedout Sub-basin exploration permits. One firm well and one contingent well are included, with drilling scheduled to commence from April 2027.
Santos, as joint venture operator, will work alongside Carnarvon and Transocean throughout the campaign. That operational role brings substantial field experience to what Carnarvon describes as a return to more regular drilling activity.
CEO Philip Huizenga called the contract signing a significant milestone. “The signing of the rig contract marks a significant milestone on our return to more regular drilling,” he said, adding that the company looks forward to drilling at least one, and potentially two, high-impact wells in 2027.
Rig selection followed a comprehensive bid evaluation process
The Transocean Equinox was not chosen quickly. Bid evaluation began in early 2025, with multiple rig candidates assessed before any final selection was made.
Timing proved decisive. The Equinox is currently completing a multi-well exploration campaign off the coast of Victoria, Australia — a program expected to wrap up by early 2026, freeing the rig well ahead of Carnarvon’s April 2027 start date. The alignment was straightforward. Beyond scheduling, the rig’s technical capability for deepwater conditions in the Bedout Sub-basin also factored into the decision.
Campaign targets high-impact prospects identified on 3D seismic data
The 2027 campaign has a clear strategic objective: define the scale of the Bedout Sub-basin’s resource potential. Four prospects have been shortlisted — Ara, Yuma, Goats Eye, and Hutton — all identified through the Bedout MegaMerge 3D seismic survey.
That seismic dataset sits at the center of Carnarvon’s exploration confidence. The company cites a 67% drilling success rate when working from high-quality 3D seismic data, a track record Huizenga referenced directly when discussing expectations for the 2027 program.
The campaign is also designed to push into new territory. Carnarvon intends to extend activity north of its previous finds and test play-types that have never been drilled in the sub-basin before — goals that signal this is more than a follow-up program. It is an attempt to open new parts of what Carnarvon calls a world-class basin.
Carnarvon’s costs capped at A$20 million, funded from existing cash reserves
One of the more notable aspects of this campaign is how Carnarvon plans to finance it. If both the firm and contingent wells are drilled, the company’s total expected cost comes to approximately A$20 million.
That figure sits comfortably within reach. As of March 31, 2026, Carnarvon held a cash balance of A$98 million, and the company has stated that its share of drilling costs will be funded entirely from that existing balance. No external financing is required. That position removes a layer of uncertainty that often surrounds exploration programs of this scale — Carnarvon can move forward on the strength of its current balance sheet alone.
Huizenga framed the contract signing as more than a logistical step. Locking in a rig two years in advance reflects a deliberate shift in pace and ambition for a company working to re-establish a regular drilling cadence.
Ahead of schedule with an early 2026 start date
Carnarvon Energy has contracted the Transocean Equinox semi-submersible rig for a Bedout Sub-basin exploration campaign starting in April 2027. The program includes one firm well and one contingent well, with joint venture operator Santos participating alongside Carnarvon and Transocean.
The rig was selected through a bid process that began in early 2025. Its current work off Victoria is expected to finish by early 2026, freeing it ahead of the planned start date. Target prospects — Ara, Yuma, Goats Eye, and Hutton — were all identified on the Bedout MegaMerge 3D seismic survey.
If both wells are drilled, Carnarvon’s total cost is expected to reach approximately A$20 million, fully covered by its A$98 million cash balance as of March 31, 2026. No additional financing is needed. The campaign aims to extend exploration north of previous discoveries and test new, previously undrilled play-types in the sub-basin.
