Jadestone Energy plc has provided an update on the testing and production performance of the Skua-11ST well at the Montara field, located offshore Australia.
Production from the Skua-11ST well began in early August 2025 and has exceeded expectations. Initial oil production rates surpassed 6,000 barrels per day (bbls/d), well above the earlier guidance of 3,500 bbls/d. Following this initial surge, production rates stabilised at around 4,400 bbls/d with the well operating on a 40% open choke, before other subsea wells at the Montara field were restarted.
The Skua-11ST well was equipped with downhole inflow control devices. These are designed to optimise the sweep and recovery of the reservoir, helping to maximise oil extraction. Moving forward, Skua-11ST and the other wells at Montara will be managed carefully to ensure the highest possible recovery from the field over the longer term.
Commenting on the results, T. Mitch Little, Chief Executive Officer of Jadestone, said, “We are pleased to report the strong initial flows from the Skua-11ST well, which will meaningfully contribute to higher production from Montara, underpinning our revised 2025 production guidance which was upgraded in July. The increase in production will also reduce Montara unit operating costs and extend field life by approximately one year.”
These encouraging results mark a significant step for Jadestone Energy, supporting both improved production forecasts and the long-term sustainability of the Montara field’s operations.
