Tamboran highlights strong Beetaloo Basin shale well performance

(WO) — Tamboran Resources has reported strong initial production results from its Shenandoah South 6H (SS-6H) well in Australia’s Beetaloo basin, highlighting the play’s growing potential as a competitive shale gas resource.

The well delivered an average 20-day initial production (IP20) rate of 10.3 MMcf/d from an 8,635-ft horizontal section, with normalized flow rates reaching 11.9 MMcf/d per 10,000 ft. The company said the results compare favorably with performance across the Marcellus Shale dry gas fairway.

During testing, the well reached a peak rate of 15.9 MMcf/d before stabilizing at 8.8 MMcf/d, indicating consistent production behavior. Tamboran noted that the well continued to unload water at the end of the test, suggesting additional cleanup and potential for improved performance over time.

Testing has now concluded as the company prepares to tie the well into the Sturt Plateau Compression Facility and begin gas sales in the third quarter of 2026.

“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 SS-2H 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.”

Tamboran plans to begin stimulation of three additional wells—SS-3H, SS-4H and SS-5H—in the second quarter, with all expected to be tied into infrastructure and brought online later this year.
