Highlights:

• The Shenandoah South 6H (SS‑6H) well 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, SS‑6H 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.

Tamboran Resources Corporation Chief Executive Officer, Mr. Todd Abbott, said:

“The SS‑6H flow test has safely and successfully delivered the technical information we were seeking, with the well demonstrating strong, stable performance and low decline characteristics.

“Over the last five days of the test, we noted behavior of the gas rate similar to the performance of the SS2H ST1 well. This aligns with our view that these wells will continue to clean up with extended production testing and deliver shallower decline profiles in early production. 

"Having met these key objectives and given the well will be used to sell gas to the Northern Territory gas network later this year, we have concluded testing in order to preserve reservoir pressure and reduce flaring and unnecessary carbon emissions. At the conclusion of testing, the well was continuing to unload water at ~270 bbl/d.

We are now preparing to commence the 2026 stimulation program, which includes completing the three remaining 10,000-foot wells required to deliver the ~40 MMcf/d under the Gas Sales Agreement to the Northern Territory.”
