Tamboran Resources Ltd (ASX:TBN, OTC:TBNRF) has successfully completed the stimulation program at the Shenandoah South 1H (SS-1H) well in the Beetaloo Basin of Australia’s Northern Territory.
The 10-stage stimulation program was carried out over a 500-metre (1,640-foot) horizontal section of Mid-Velkerri B Shale.
Encouragingly, it delivered a proppant intensity of 2,212 pounds per foot (lb/ft) and achieved rates of 100 barrels per minute (bpm) using slickwater, a first in the Mid Velkerri B Shale and in-line with current US shale basin stimulation designs.
Beetaloo Basin record
Managing director and CEO Joel Riddle said: “The operations team has done an excellent job in completing the stimulation program at the SS-1H well as expected. Thank you to our team and contractors for their efforts in completing the successful program.
“The operations went extremely well with the team achieving injection rates of up to 100 bpm, a Beetaloo Basin rate record, and average proppant injection per stage of 356,000 pounds, in line with our initial design.
"The team engineered a repeatable stimulation formula, which is a significant milestone for Tamboran that is expected to lead to more efficient and lower cost programs in the future.”
What comes next?
Tamboran, on behalf of the Beetaloo Joint Venture (BJV), now plans to install production tubing ahead of the start of flow back of stimulation fluid and 30-day initial production (IP30) testing in mid-December, subject to timing of gas breakthrough.
“Most importantly, the success of the program positions us to announce IP30 flow rates during the first quarter of 2024, subject to timing to flow back stimulation fluid and weather conditions,” Riddle said.
"Delivery of commercial flow rates is expected to allow us to progress towards the sanctioning of the proposed 40 MMcf/d Pilot Project at Shenandoah South during the first half of 2024.”
