Tamboran (B2) Pty Ltd. observed strong dry gas shows in the Shenandoah South 1H (SS1H) pilot hole in exploration permit 117 in in the Beetaloo sub-basin, Northern Territory, Australia, partner Falcon Oil & Gas Ltd. said in a release Aug. 30.

The well, the first of two horizontal wells to be drilled in 2023, is about 60 km south of the A2H well site (OGJ Online, Aug. 2, 2023). The Helmerich & Payne rig reached 3,300 m TVD in 21.5 days, drilling at 153 m/d, setting a record for wells drilled below 3,000 m in the sub-basin.

The well intersected 90 m of the Amungee Member B-shale, which is the thickest section seen in the Beetaloo sub-basin depocenter to date. Logging of the formation indicates potentially higher porosity and gas saturation relative to offset wells.

Initial evaluation confirms reservoir continuity of the Amungee Member B-shale over 150 km between Amungee NW-2H and Beetaloo W-1 wells. This includes a target development area of about 1 million acres where the shale depth exceeds 2,700 m.

Tamboran will commence a 1,000-m horizontal section within the shale formation ahead of a stimulation program of up to 10 stages over a 500-m section, which is planned for fourth-quarter 2023.

Tamboran is operator of EP117 (77.5%). Falcon Oil & Gas holds the remaining 22.5%.
