Tamboran (B2) Pty Ltd. flow tested the Shenandoah S2-2H ST1 well and started the 2025 horizontal well drilling campaign in Beetaloo sub-basin, Northern Territory, Australia, said partner Falcon Oil & Gas Ltd. in a July 14 release.
Well S2-2H ST1 achieved an average 60-day initial production (IP60) flow rate of 6.8 MMscfd in a 5,483 ft interval across a 35-stage stimulated horizontal within the Amungee Member B-Shale in the sub-basin. It is the highest IP60 result in Beetaloo to date.
The exit rate maintains a steady, low-declining curve at 6.4 MMcfd with a flowing wellhead pressure of about 720 psi and has exhibited less decline than that of the Shenandoah South 1H well (SS-1H) over the last 30 days of testing.
The 2025 drilling campaign has now commenced targeting up to three 10,000-ft horizontal wells to be drilled back-to-back over the next few months. This will complete the drilling phase of the five-well Shenandoah South pilot program.
Beetaloo is an onshore Proterozoic and Cambrian tight oil and gas exploration basin covering about 8.7 million acres and is relatively underexplored.
