Highlights
锟� The Shenandoah South 6H (SS-6H) well delivered a record average 20-day initial production (IP20)
flow rate of 10.3 million cubic feet per day (MMcf/d) from an 8,635-foot (2,632-metre) horizontal
section within the Mid Velkerri B Shale.
锟� On a normalized basis, SS-6H achieved a flow rate of 11.9 MMcf/d per 10,000 feet, which compares
favorably to the average performance of more than 11,000 producing wells in the Marcellus Shale
dry gas fairway with over 12 months of production history.
锟� The flow test has now been concluded, with the well delivering a stable rate of
8.8 MMcf/d (normalized to 10.2 MMcf/d per 10,000 feet) at a flowing wellhead pressure of
approximately 580 psi.
锟� At the conclusion of the flow test, water was continuing to unload at a rate of ~270 barrels per
day (bbl/d), indicating the well was still in the process of cleaning up.
锟� All key technical objectives of the flow test have been achieved, with the well demonstrating
sustained, stable rates over the last five days of testing, similar to that observed at the SS-2H ST1
well.
锟� Testing has been intentionally curtailed to avoid unnecessary flaring and carbon emissions, and
preserve reservoir energy ahead of tie-into the Sturt Plateau Compression Facility (SPCF) and
the commencement of gas sales in 3Q 2026.
锟� The 2026 stimulation campaign for the Shenandoah South 3H, 4H and 5H wells is planned to
commence in the second quarter, with all three wells expected to be tied into the SPCF and
brought into production during 3Q 2026.
Tamboran Resources Corporation Chief Executive Officer, Mr. Todd Abbott, said:
锟絋he SS-6H flow test has safely and successfully delivered the technical information we were seeking, with
the well demonstrating strong, stable performance and low decline characteristics.
锟絆ver the last five days of the test, we noted behavior of the gas rate similar to the performance of the SS2H ST1 well. This aligns with our view that these wells will continue to clean up with extended production
testing and deliver shallower decline profiles in early production.
锟紿aving met these key objectives and given the well will be used to sell gas to the Northern Territory gas
network later this year, we have concluded testing in order to preserve reservoir pressure and reduce
flaring and unnecessary carbon emissions. At the conclusion of testing, the well was continuing to unload
water at ~270 bbl/d.
We are now preparing to commence the 2026 stimulation program, which includes completing the three
remaining 10,000-foot wells required to deliver the ~40 MMcf/d under the Gas Sales Agreement to the
Northern Territory.锟�
Shenandoah South 6H flow results
The SS-6H well achieved average IP20 flow rates of 10.3 MMcf/d from an 8,635 feet (2,632 metres) lateral
section in the Mid Velkerri B Shale. The well was stimulated with 57 stages and a toe stage covering over
3,030 metres (9,943 feet) at an average of 50 锟� 60-metres (164 - 197-foot) interval spacing within the Mid
Velkerri B Shale.
An obstruction has been left in the wellbore obstructing flow from 8 stages and the toe over 397.7 metres
(1,305-foot). Given this impediment, it is expected that the gas contribution is from 49 stages across 2,632
metres (8,635 feet).
During the 20-day production testing period, the choke was opened from 20/64锟� to 60/64锟� at staged
intervals and held constant over last 15 days. Gas rates declined from 15.9 MMcf/d to 8.8 MMcf/d, with an
average IP20 flow rate of 10.3 MMcf/d and cumulative production of 205.6 MMcf over that period. Flowing
wellhead pressures were drawn down from 4,499 to 582 psi.
This ASX announcement was approved and authorised for release by Mr. Todd Abbott, the Chief
Executive Officer of Tamboran Resources Corporation.
