Tamboran Resources (ASX:TBN) said that the stimulation program of the Shenandoah South-6H well in the Beetaloo basin in the Northern Territory began in November, with the program up to 60 stages and expected to conclude by the end of the year, according to a Friday Australian bourse filing.

It completed the first batch drilling program at the Shenandoah South Pilot Area, where it holds 47.5% working interest in 20,309 acres, with the Shenandoah South-4H, Shenandoah South-5H, and Shenandoah South-6H wells drilled and cemented with 10,000-foot horizontal sections within the primary Mid Velkerri B shale target.

An issue with the coil tubing in preparation for the stimulation on the Shenandoah South-4H well resulted in the decision to stimulate the Shenandoah South-6H well first. Recovery of the coil tubing is planned to follow the end of the Shenandoah South-6H stimulation. IP30 flow testing of Shenandoah South-6H is expected to be conducted during the first quarter of 2026, subject to weather conditions and soaking duration.

Tamboran expects to stimulate the remaining three drilled and uncompleted wells before the start of gas sales.

Its proposed acquisition of Falcon Oil & Gas is expected to close in the first quarter of 2026.
