Carnarvon Energy (ASX:CVN) reported a 92% increase in its prospect resource inventory across the Bedout Sub-Basin permits on Australia's North-West Shelf, according to a Tuesday filing with the Australian bourse.
The company said it now estimates gross prospective resources of about 6.26 billion barrels of oil equivalent across 130 prospects, up from 3.26 billion barrels of oil equivalent reported in June 2025.
"This step‑change reflects significantly improved subsurface imaging from the seamless integration of multiple high‑quality seismic surveys within the Mega‑Merge dataset," the company said.
Exploration drilling at the Bedout joint venture is due to start from April 2027, per the filing.
