Tamboran Resources Corporation has kickoff stimulation activities of the Shenandoah South 2H sidetrack (SS-2H ST1) and the Shenandoah South 3H (SS-3H) wells at its Beetaloo Basin exploration permit EP 98 within the Greater McArthur Basin in the Northern Territory, Australia.
Well stimulation commenced
The company is planning to pump up to 119 stimulation stages across the two wells with reduced spacing between stages.
The SS-2H ST1 well is planned to include 43 stages over a 5,427-foot (1,654-metre) horizontal section and the SS-3H well is planned to include 76 stages over a 9,766- foot (2,977-metre) horizontal section.
Tamboran Resources managing director and CEO Joel Riddle said: “This stimulation campaign is planned to be the largest in the Beetaloo Basin to date, with up to 119 stages over a full lateral length of 15,193 feet (~4,631 meters) across the two wells, an average of ~127 feet per stimulated stage.
“Importantly, these wells are planned to be among the first to provide reliable energy to the Northern Territory, with production expected to feed into the proposed 40 MMcf/d Shenandoah South Pilot Project.
“We have successfully undertaken stimulation programs during the wet season in the Basin over the last two years, with campaigns at Amungee 2H (2022/23) and Shenandoah South 1H (2023/24). This experience gives us confidence in our ability to safely and efficiently conduct these operations year-round.”
The stimulation testing follows the successfully drilling, casing and cementing of the wells late last year.

Modern stimulation equipment
The campaign is being conducted with Liberty Energy modern stimulation equipment, which is the first 80,000 hydraulic horsepower (HHP) frac spread imported into the Beetaloo Basin from the US.
Tamboran expects the increased horsepower from the Liberty equipment will result in a greater than 25% increase in proppant intensity of more than 2,800 pounds per foot, as compared with Shenandoah South 1H well. All stages are being pumped with a slickwater fluid design.
Riddle said: “We are excited to commence the stimulation program for the SS-2H ST1 and SS-3H wells in the Beetaloo Basin with Liberty Energy's modern stimulation equipment.
“The increased horsepower of this equipment is expected to deliver a step change in stimulation efficiency and proppant intensity compared to previous wells completed in the Basin."
