Falcon Oil & Gas Ltd has announced the completion of the stimulation programme for the Shenandoah South SS2-1H horizontal well, carried out with its joint venture partner Tamboran (B2) Pty Ltd in Australia’s Beetaloo Sub-basin. The well, drilled over a horizontal section of approximately 3,050 metres, was stimulated across 58 stages within the Amungee Member B Shale formation.
Technical optimisation and cost reduction
The programme employed Liberty Energy’s latest-generation stimulation equipment and achieved wellhead injection rates exceeding 100 barrels per minute. The original design was adjusted to increase stage spacing from 50 to 60 metres, reducing the total number of stages required. This revision is expected to lower costs in future stimulation campaigns.
A technical issue encountered during well cleanout limited approximately 2,632 metres—or 86%—of the horizontal section to contributing to unimpeded flow. A remaining portion of 419 metres may experience flow restrictions.
Testing phase and 2026 schedule
The SS2-1H well will undergo a 30-day soak period followed by a 30-day flow test. Initial 30-day production rates (IP30) are anticipated in the first quarter of 2026. Three additional wells, including the second well from the 2024 drilling campaign, are scheduled for stimulation in the first half of 2026.
These wells are part of the Shenandoah South Pilot Project, which targets the delivery of 40 million cubic feet per day under a gas sales agreement with the Northern Territory Government. Deliveries remain subject to weather conditions and final stakeholder approvals.
Financial position and contractual outlook
Falcon Oil & Gas Australia Limited, a subsidiary of Falcon, holds no financial interest in the three wells drilled in 2025, following a previous decision to reduce its participation to 0%, eliminating its cost exposure. The company also confirmed progress on the definitive agreement with Tamboran Resources Corporation, which is expected to close in the first quarter of 2026.
