Tamboran Resources Corporation (ASX:TBN, NYSE:TBN, OTC:TBNRL) has wrapped up stimulation activities at its Shenandoah South 6H (SS-6H) well, completing 58 stages over a 10,009-foot (~3,050-metre) stimulated length in the Mid Velkerri B Shale using Liberty Energy’s (NYSE: LBRT) modern stimulation fleet.
Optimisation of the stimulation design during the campaign allowed TBN to widen stage spacing from 164 feet (~50 metres) to 196 feet (~60 metres). While that reduced the total number of stages, Tamboran expects the change to translate into lower costs for future stimulation programs without compromising well performance.
“Congratulations to the Tamboran and Liberty teams for delivering our largest Beetaloo Basin stimulation program with 58 stages across the full 10,009-foot horizontal section. The team averaged three stages per day for a single frac sequence, setting a new Tamboran record, and reached a peak of six stages in a single day. This performance reflects the successful application of US shale learnings that we are bringing to the Beetaloo Basin,” Tamboran Resources Corporation chairman and interim CEO Richard Stoneburner said.
“An equipment issue has meant that it is likely that 86% of the horizontal section will be usable and have unimpeded flow. We plan to implement the lessons learned ahead of the three well stimulation campaign, which is planned to commence in 1H 2026.
“We have ensured that all critical equipment is on site ahead of the wet season to complete the construction of the SPP and the SPCF, and construction remains on schedule for first gas sales in mid-2026.”

About the stimulation
Across the 58 stages, proppant intensity averaged 2,206 pounds per foot, with wellhead injection rates consistently above 100 barrels per minute. The SS-6H completion was designed to mirror the earlier SS-1H program, which Tamboran has previously described as technically successful.
During clean-out operations, Tamboran determined that 8,635 feet (~2,632 metres), or 86% of the SS-6H lateral, is expected to contribute to unimpeded flow. An equipment issue may impede flow from the remaining 1,374-foot (~419-metre) section at the toe, although the company still anticipates the bulk of the lateral to perform as planned.
What’s next?
Tamboran is now preparing to complete SS-6H with tubing ahead of initial flowback. The well is planned to be soaked for about 30 days before a 30-day flow test, currently scheduled for 1Q 2026.
Stimulation of the remaining three drilled wells at Shenandoah South — SS-3H, SS-4H and SS-5H — is planned for the first half of 2026, subject to wet season conditions. Following stimulation, those wells are expected to be completed with tubing and tied into the Sturt Plateau Compression Facility (SPCF) ahead of the start of production.
As at the end of November 2025, the SPCF was about 74% complete. On the midstream side, APA Group’s (ASX: APA) Sturt Plateau Pipeline (SPP) had reached 98% of welding, 74% of trenching and 71% of pipe installation, positioning the project for connection once the upstream wells are brought online.
