• Tamboran successfully completed the 2025 Shenandoah South drilling program, the largest ever in the Beetaloo Basin
• The program included batch drilling of three wells with 10,000-foot laterals, delivered within the 35-day forecast
• Tamboran used new Baker Hughes anti-vibration drilling technology, resulting in record performance

Tamboran Resources Corporation has successfully completed the 2025 Shenandoah South drilling program, the largest program ever conducted in the Beetaloo Basin. The program included the batch drilling of the Shenandoah South -4H (SS-4H), -5H and -6H wells, each successfully completed with a target lateral length of 10,000-feet. The three wells have been successfully cased and suspended ahead of stimulation activities. The average spud-to-TD (total depth) across the program was 26.7 days, with the drilling and casing time delivered within the 35-day forecast. The program saw an increase in efficiency driven by the application of new Baker Hughes (NASDAQ: BKR) anti-vibration drilling technology. This resulted in Tamboran drilling its fastest horizontal section in the Mid Velkerri B Shale to date in the SS-6H well, reaching over 1,100 metres (3,603 feet) in a day. Tamboran plans to complete the SS-4H well in 4Q 2025, which includes up to 60 stages across the full 10,000-foot horizontal section within the Mid Velkerri B Shale using the imported Liberty Energy (NYSE: LBRT) modern stimulation equipment. The SS-4H well is planned to be flow tested for 30 days ahead of being shut-in for future gas sales.

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.
