Falcon Oil & Gas has announced that Shenandoah SS2-1H (SS2-1H) achieved an average 20-day initial production (“IP20”) flow rate of 10.3 million cubic feet per day (MMcf/d) over 2,632-metres (8,635-foot) across a 57 stage stimulated length within the Amungee Member B-Shale in the Beetaloo Sub-basin, Northern Territory, Australia.
Points to note:
- The normalized flow rate of 11.9 MMcf/d over an extrapolated 10,000-foot horizontal section compares favourably to the average performance of more than 11,000 producing wells in the Marcellus Shale dry gas fairway with over 12 months of production history.
- The exit rate trajectory continues a steady, low-declining curve at 8.8 MMcf/d (normalized at 10.2 MMcf/d per 10,000-feet) with a flowing wellhead pressure of ~580 psi. The steady state decline curve on SS2-1H is consistent with that achieved from the Shenandoah SS2-2H ST1 (“SS-2H ST1”).
- Testing has been intentionally curtailed to avoid unnecessary flaring and carbon emissions and preserve reservoir energy ahead of tie-into the Sturt Plateau Compression Facility (“SPCF”) and the commencement of gas sales in 3Q 2026.
- The 2026 stimulation campaign for the Shenandoah South 3H, 4H and 5H wells is planned to commence in the second quarter, with all three wells expected to be tied into the SPCF and brought into production during 3Q 2026.
- As previously announced, Falcon Australia opted to reduce its participating interest in the three wells drilled in 2025 to 0% (which includes the SS2-1H well), with no cost exposure.
- For further details on the SS2-1H flow test please refer to Appendix A.
Philip O’Quigley, CEO of Falcon commented:
'The IP20 flow rate results announced today of 10.3 MMcf/d, is another positive development as we move towards commercial production. As further results become available, we look forward to updating the market.'
