EP 98 Operational Update: SS-2H ST1 Stimulation Delivers Material Step Change in Beetaloo Completion Efficiency

In This Article:

Highlights

  • Tamboran Resources successfully completed stimulation activities over 35 stages across a 5,483-foot (1,671-metre) horizontal section in the Mid Velkerri B Shale within the Shenandoah South 2H sidetrack (SS-2H ST1) well. The stimulation was conducted using the Liberty Energy (NYSE: LBRT) modern stimulation equipment.

  • The SS-2H ST1 completion operations achieved five stages over a 24-hour period on multiple days, exceeding previous Beetaloo Basin records.

  • Average proppant intensity of 2,706 pounds per foot (lb/ft) across the 35 completed stages exceeded all previous completion activities in the Beetaloo Basin to date and achieved wellhead injection rates above 100 barrels per minute (bpm).

  • The SS-2H ST1 well will be completed ahead of clean out activities and the commencement of initial flow back and extended production testing.

  • Further updates on the completion of the Shenandoah South 3H (SS-3H) well will be provided in due course.

NEW YORK, February 07, 2025--(BUSINESS WIRE)--Tamboran Resources Corporation (NYSE: TBN, ASX: TBN):

Tamboran Resources Corporation Managing Director and CEO, Joel Riddle, said:

"The SS-2H ST1 stimulation operations were successfully completed across 35 stimulated stages over the 5,483-foot horizontal section in the Mid Velkerri B Shale.

"The increased efficiency from the Liberty stimulation equipment has delivered Beetaloo Basin completion records for average proppant injection intensity and treating rates over 100 bpm.

"The decision was made during the completion activities to optimize the stimulation design by increasing the spacing between stages to ~168 feet, which resulted in improved efficiency.

"We will now focus on completing and cleaning out the SS-2H ST1 well ahead of the commencement of initial flow back and extended production testing."
