Falcon Oil & Gas and its joint venture (JV) partner Tamboran B2 have completed the stimulation programme at the Shenandoah South SS2-1H well in the Beetaloo sub-basin, Northern Territory (NT), Australia.
The partners stimulated 58 stages along a horizontal section of approximately 3,050m within the Amungee Member B Shale, using an average proppant intensity of 2,206 pounds per foot.

Wellhead injection rates during the operation remained above 100 barrels per minute, and the programme used Liberty Energy’s modern stimulation equipment.
During the campaign, the partners optimised the stimulation design by increasing stage spacing from around 50m to 60m, reducing the total number of stages required.
This change is expected to lower the costs of future stimulation activities.
After an equipment issue encountered during the well clean-out, the partners determined that roughly 2,632m of the horizontal section (86%) will contribute to unimpeded flow.

The well will undergo a 30-day soak period after completion with tubing, followed by a 30-day flow test. The partners expect to report 30-day initial production (IP30) flow rates during the first quarter of 2026 (Q1 2026).
In the first half of 2026 (H1 2026), three wells, including the second well from the 2024 drilling campaign, are scheduled for stimulation ahead of planned gas sales.
All wells in the Shenandoah South pilot project are expected to deliver the contracted 40 million cubic feet per day.
This volume is required under the gas sales agreement with Australia’s NT Government, subject to weather and final stakeholder approvals.
Falcon Australia previously opted to reduce its participating interest in the three wells drilled in 2025 to zero, with no cost exposure.
Falcon CEO Philip O’Quigley said: “This is another major milestone for the BJV partners with the stimulation of the first 3,050m horizontal well.
“With three more wells to be stimulated in H1 2026 and planned gas sales to commence shortly thereafter, 2026 is going to be a very busy and exciting year in the Beetaloo.”
Tamboran B2 is a subsidiary of Tamboran B1, a 50:50 JV between Tamboran Resources and Daly Waters Energy.
O’Quigley added: “The definitive agreement entered into between Falcon and Tamboran Resources Corporation is progressing and is expected to close in Q1 2026.”
Last year, Falcon and Tamboran B2 started drilling the Shenandoah S2-4H well, the second in the Shenandoah South pilot project, targeting the Amungee Member B Shale.
The SS4H well is being drilled from the same pad as the Shenandoah S2-2H ST1 sidetrack, using the H&P super-spec FlexRig Flex 3 rig.
In October this year, Tamboran Resources agreed to acquire Falcon to become a major acreage holder in the Beetaloo basin, with around 2.9 million prospective acres.
Tamboran will acquire all Falcon subsidiaries for 6.5 million shares of its common stock and $23.7m (A$35.61M) in cash, valuing Falcon at approximately $172m (€146.33m).
