亮点
— Shenandoah South 2H 侧钻井 (SS-2H ST1) 在 Mid Velkerri B 页岩内 5,483 英尺的受控水平段实现了 Beetaloo 盆地平均 90 天初始生产 (IP90) 流量，即每天 670 万立方英尺 (MMcf/d)，创下了历史新高。
— 在过去 30 天里，SS-2H ST1 井的流量增加了约 2%，无需任何井下干预，并保持 44/64 英寸节流。
— 在 90 天结束时，该井的流量为每天 650 万立方英尺，井口压力约为 700 psi，比第 60 天结束时下降了约 3%。
— SS-2H ST1 井现已暂停生产，以便通过位于预计于2026年中期完成，但需视天气情况和最终利益相关者的批准而定。
” 2025年Shenandoah South的三口井钻探活动继续推进，SS-5H和SS-6H井的中间段已成功钻探。该钻机目前正在钻探SS-4H井的中间段。该活动是Beetaloo盆地首次实施批量钻探的多井钻探项目。
” SS-4H井中间段完工后，该钻机计划开始钻探这三口井的10,000英尺水平段。Tamboran

Resources Corporation董事长兼代理首席执行官Richard Stoneburner表示：
“与我职业生涯中见过的数百口井相比，SS-2H ST1井的性能和特性是独一无二的。”过去30天，在没有井下干预或节流阀调整的情况下，产量已增至650万立方英尺/天，我相信增产项目期间基质连通性有所增强。SS-2H ST1井的成果代表了另一个令人鼓舞的数据点，让我们更好地了解了Velkerri B页岩的最终性能和采收率。

“最重要的是，在90天的测试期结束时，油井继续缓慢地恢复，这表明它本可以在测试期结束后维持目前的产量。这些数据对于我们准备在年底前在Shenandoah South地区完成首个10,000英尺水平段的增产至关重要。

” 这些结果，加上2024年的SS-1H流量，展现了Shenandoah South地区周边大片土地的巨大潜力，我们目前正在该地区开发一个约40万英亩的农场。预计未来几年将开发农场下的土地，以弥补东海岸天然气市场预计出现的缺口。Shenandoah

South 2H ST1 流量结果
坦博兰运营的勘探许可证 (EP) 98 中的 SS-2H ST1 井在 Mid Velkerri B 页岩 5,483 英尺（1,671 米）水平段实施 35 阶段增产计划后，平均 IP90 流量为 6.7 MMcf/d，累计产量为 601.2 MMcf。

在 90 天的期间内，流动井口压力从 4,565 psi 降至 ~700 psi。在从第 61 天到第 90 天的 30 天测试期间，气体产量从 6.4 MMcf/d 增加到 6.5 MMcf/d。在过去 30 天内，该井的平均流量达到 6.4 MMcf/d，累计产量达到 192.8 MMcf。

井口流动压力从722 psi降至700 psi。节流阀尺寸保持不变，为44/64英寸。

Highlights
• The Shenandoah South 2H sidetrack (SS-2H ST1) well achieved a Beetaloo Basin record average 90-day initial production (IP90) flow rate of 6.7 million cubic feet per day (MMcf/d) over a 5,483- foot stimulated horizontal within the Mid Velkerri B Shale.
• Over the last 30 days, flow rates from the SS-2H ST1 well have increased by ~2% without any downhole intervention and maintaining a 44/64” choke.
• At the completion of the 90-day period, the well was flowing at 6.5 MMcf/d with a wellhead pressure of ~700 psi, a ~3% decline from the end of Day 60.
• The SS-2H ST1 well has now been suspended ahead of the commencement of gas sales to the Northern Territory Government via the Sturt Plateau Compression Facility (SPCF) in mid-2026, subject to weather conditions and final stakeholder approvals.
• The three well 2025 Shenandoah South drilling campaign continued to progress with the intermediate section of the SS-5H and -6H wells successfully drilled. The rig is currently drilling the intermediate section of the SS-4H well. The campaign is the first multi-well drilling program implementing batch drilling in the Beetaloo Basin.
• On completion of the intermediate section of the SS-4H well, the rig is planned to commence drilling of the 10,000-foot horizontal sections of the three wells.

Tamboran Resources Corporation Chairman and Interim CEO, Richard Stoneburner, said:
“The performance and character of the SS-2H ST1 well is unique compared to hundreds of wells I have seen in my career. With flow rates increasing over the last 30 days to 6.5 MMcf/d, without downhole intervention or adjustments to choke, I believe we are seeing the enhanced matrix connectivity achieved during the stimulation program. The SS-2H ST1 well represents another encouraging data point as we better understand the Velkerri B Shale’s ultimate performance and recovery.

“Most importantly, at the end of the 90-day period, the well continued to slowly clean up, suggesting that it could have sustained the current rate beyond the testing interval. This data will be important as we prepare to stimulate our first 10,000-foot horizontal section in the Shenandoah South area by the end of the year.

“These results, combined with the SS-1H flow rates in 2024, show the significant potential of the large acreage position surrounding the Shenandoah South area, where we are currently progressing a farm down of ~400,000 acres. The farm down acreage is expected to be developed over the coming years to supply into the anticipated shortfall emerging in the East Coast gas market.”

Shenandoah South 2H ST1 flow results
The SS-2H ST1 well in Tamboran-operated Exploration Permit (EP) 98 achieved an average IP90 flow rate of 6.7 MMcf/d with cumulative production of 601.2 MMcf following the 35-stage stimulation program across a 5,483 feet (1,671 metres) lateral section in the Mid Velkerri B Shale.

Over the 90-day period, the flowing wellhead pressure was drawn down from 4,565 to ~700 psi. During the 30-day testing period from Day 61 to 90, gas rates increased from 6.4 MMcf/d to 6.5 MMcf/d. Over the final 30 days, the well achieved an average flow rate of 6.4 MMcf/d with cumulative production of 192.8 MMcf.

The flowing wellhead pressure was drawn down from 722 to 700 psi. The choke size was unchanged at 44/64”.
