Tamboran Resources Corporation (ASX:TBN, NYSE:TBN, OTC:TBNRL) has completed its 2025 Shenandoah South campaign — the largest drilling program undertaken in the Beetaloo Basin — delivering three horizontal wells with 10,000-foot laterals and setting a new operational speed benchmark.
The program comprised batch drilling of Shenandoah South-4H (SS-4H), SS-5H and SS-6H. All three wells reached total depth and were successfully cased and suspended ahead of stimulation activities. Average spud-to-total depth was 26.7 days, inside the 35-day forecast.
Operational efficiency improved through the use of new Baker Hughes anti-vibration drilling technology, enabling Tamboran to achieve its fastest horizontal section to date in the Mid Velkerri B Shale on SS-6H, at more than 1,100 metres (m) (3,603 feet) drilled in a single day.

“We are proud to have delivered the largest drilling program ever conducted in the Beetaloo Basin, which included batch drilling of three wells at the Shenandoah South 2 well pad. The wells are crucial to supplying gas to the Northern Territory network under the long-term Gas Sales Agreement with the Northern Territory Government, with first gas sales on track for mid-2026,” Tamboran Resources Corporation chairman and interim CEO Richard Stoneburner said.
“The three wells were drilled efficiently, with an average drilling time of less than 27 days from spud to TD and spud to completion of cementing time within the AFE of 35 days. Importantly, we have accelerated learnings in the Beetaloo Basin through the use of modern US drilling technologies, which has resulted in record performance throughout this campaign.
What’s next?
Next steps include completing SS-4H in the fourth quarter of 2025 with up to 60 stimulation stages across the full 10,000-foot horizontal section in the Mid Velkerri B Shale, using Liberty Energy’s modern stimulation equipment.
“The three wells have now been cased and suspended. The SS-4H well is planned to be stimulated in 4Q 2025, with the remaining two wells, plus the reinforced SS-3H well, to be stimulated in 1H 2026.
“We are excited to welcome back the team from Liberty Energy to the Beetaloo Basin to conduct a 60-stage stimulation program within the SS-4H well. We are looking forward to delivering an IP30 flow test from our first two-mile (10,000-feet) lateral well in the coming months.”
Tamboran plans a 30-day flow test of SS-4H before the well is shut-in for future gas sales.
