Tamboran Resources reports robust and stable gas production from its Shenandoah South 6H well, marking a key milestone ahead of planned gas sales in late 2026.
- SS-6H well achieves 10.3 MMcf/d average initial 20-day flow rate
- Normalized flow rate of 11.9 MMcf/d per 10,000 feet lateral
- Testing concluded early to preserve reservoir pressure and reduce emissions
- 2026 stimulation campaign planned for three additional wells
- Performance compares favourably with established Marcellus Shale wells
Strong Production from SS-6H Well
Tamboran Resources Corporation has announced encouraging results from its Shenandoah South 6H (SS-6H) well in the Beetaloo Basin, Northern Territory. The well delivered an average initial 20-day production (IP20) flow rate of 10.3 million cubic feet per day (MMcf/d) from an 8,635-foot horizontal section within the Mid Velkerri B Shale. When normalised to a 10,000-foot lateral, this equates to an impressive 11.9 MMcf/d, underscoring the well’s strong productivity.
The flow test, conducted over 20 days, showed stable gas rates with a gradual decline from a peak of 15.9 MMcf/d to 8.8 MMcf/d by the end of the period. Notably, the well continued to unload water at around 270 barrels per day, indicating ongoing cleanup and potential for sustained production.
Strategic Testing and Environmental Considerations
Todd Abbott, Tamboran’s CEO, highlighted that testing was intentionally curtailed to preserve reservoir energy and minimise flaring and carbon emissions ahead of the well’s integration into the Sturt Plateau Compression Facility (SPCF). Gas sales are expected to commence in the third quarter of 2026, marking a significant step towards commercialisation.
The SS-6H well’s performance aligns closely with Tamboran’s earlier SS-2H ST1 well, suggesting a consistent and reliable production profile with low decline rates. This bodes well for the company’s broader development plans in the Beetaloo Basin.
Looking Ahead: Expansion and Gas Sales
Tamboran plans to initiate a stimulation campaign in the second quarter of 2026 targeting three additional wells; Shenandoah South 3H, 4H, and 5H. These wells are expected to be tied into the SPCF and contribute to the company’s gas sales agreement, which aims to deliver approximately 40 MMcf/d to the Northern Territory gas network.
Comparisons with the prolific Marcellus Shale in the United States show that Tamboran’s wells are performing favourably, reinforcing confidence in the Beetaloo Basin’s potential as a significant natural gas resource.
Technical Details and Challenges
The SS-6H well was stimulated with 57 fracture stages over a lateral length of nearly 10,000 feet. However, an obstruction remains in the wellbore affecting flow from eight stages and the toe section, which may limit total production capacity. Despite this, the gas contribution from the effective 49 stages has demonstrated strong flow rates.
Tamboran holds a 44.375% interest in the well and continues to focus on operational efficiency and environmental stewardship as it advances its development program.
Bottom Line?
Tamboran’s SS-6H results set a solid foundation for upcoming production and underline the Beetaloo Basin’s growing significance in Australia’s gas landscape.
Questions in the middle?
- How will the obstruction in the SS-6H wellbore impact long-term production forecasts?
- What are the risks and timelines associated with the upcoming stimulation campaign for the three additional wells?
- How will infrastructure developments like the Sturt Plateau Compression Facility influence gas sales and market access?
