Jadestone Energy PLC has provided an update on the testing of the Skua-11ST development well at the Montara field, located offshore Australia.
As previously disclosed, production from the Skua-11ST well began in early August 2025. Initial oil production rates from the well surpassed expectations, exceeding 6,000 barrels per day (bbls/d), significantly higher than the prior estimate of 3,500 bbls/d. Following this, the production rates stabilised at 4,400 bbls/d with a 40 percent open choke, prior to the restart of the Montara field’s other subsea wells.
The Skua-11ST well was completed with downhole inflow control devices, which aim to enhance reservoir sweep and recovery. This well, along with the other Montara wells, will be managed strategically to maximize overall recovery from the Montara field.
T. Mitch Little, chief executive officer of Jadestone, remarked on the situation, stating, “The strong initial flows from the Skua-11ST well will significantly contribute to increased production from Montara, supporting our revised 2025 production guidance, which was upgraded in July. This production boost will also help reduce Montara’s unit operating costs and extend the field’s lifespan by approximately one year.”
