Xstate Resources has provided an operational update on its Diona-1 well at ATP2077 in South West Queensland’s Surat-Bowen Basin, where the company holds a 51% interest alongside Elixir Energy, which holds the remaining 49%.

The company said stimulation and flow testing operations are progressing smoothly and in line with the operator’s schedule, with all zones now successfully stimulated.

Xstate stated that stimulation and flow testing operations at Diona-1 are progressing smoothly and according to schedule.

The company confirmed all zones have been successfully stimulated and said stimulation equipment is being demobilised from site following that work.

During the routine flowback period following final stimulation, the company said indications of methane gas were recorded on a hand held gas meter.

The release did not provide further technical detail beyond confirming that the indications were recorded during this process.

The next phase of operations involves the coil tubing unit milling out temporary plugs ahead of running the completion, after which Xstate said a 14-day flow testing and pressure monitoring process will commence.

Xstate noted that it acquired the Diona project in April 2025 and said ATP2077 forms part of its current oil and gas portfolio.
