Tamboran (B2) Pty Ltd. confirmed reservoir continuity in Beetaloo sub-basin, 600 km south of Darwin, after drilling the Shenandoah South 1H (SS1H) well in the Northern Territory, Australia, partner Falcon Oil & Gas Ltd. said in a release Sept. 18.

The well is in exploration permit (EP) 117 and has been drilled to a total measured depth of 4,300 m, including a horizontal section over 1,074 m in length in the Amungee Member B-shale, with casing and cementing also complete (OGJ Online, Aug. 30, 2023).

Logging of the Amungee Member B-shale formation indicates potentially higher porosity and gas saturation relative to other wells drilled targeting the same formation. Initial evaluation confirms reservoir continuity of the Amungee Member B-shale over 150 km between Amungee NW-2H (A2H) and Beetaloo W-1 wells. This includes a target development area of about 1 million acres where the shale depth exceeds 2,700 m. A stimulation program of up to 10 stages over a 500-m section is expected to begin in fourth-quarter 2023.

The Helmerich & Payne super spec Flex 3 rig will now be mobilized to the Amungee NW-3H (A3H) well site which will be drilled from the same pad as A2H.

A3H is the second of the two-well program in 2023 and will target the Amungee Member B-Shale at an estimated depth of 2,450 m TVD (total vertical depth), with spudding of the well expected by end-September.

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