• SS-6H well achieved average IP20 flow rate of 10.3 MMcf/d from 8,635-foot horizontal section
• Normalized to 10,000 feet, the well achieved 11.9 MMcf/d, comparable to top Marcellus Shale wells
• Testing intentionally curtailed to preserve reservoir energy ahead of gas sales in 3Q 2026

Tamboran Resources Corporation's Shenandoah South 6H (SS-6H) well in the Beetaloo Basin delivered a record average 20-day initial production (IP20) flow rate of 10.3 million cubic feet per day (MMcf/d) from an 8,635-foot (2,632-metre) horizontal section within the Mid Velkerri B Shale. On a normalized basis, the well achieved a flow rate of 11.9 MMcf/d per 10,000 feet, which compares favorably 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 flow test has now been concluded, with the well delivering a stable rate of 8.8 MMcf/d (normalized to 10.2 MMcf/d per 10,000 feet) at a flowing wellhead pressure of approximately 580 psi. At the conclusion of the flow test, water was continuing to unload at a rate of ~270 barrels per day (bbl/d), indicating the well was still in the process of cleaning up. All key technical objectives of the flow test have been achieved, with the well demonstrating sustained, stable rates over the last five days of testing, similar to that observed at the SS-2H ST1 well. 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.
