Tamboran Resources Ltd (ASX:TBN) has encountered significant gas shows that are indicative of strong commercial flow rates from drilling at Tanumbirini 3H (T3H) well within the Beetaloo Sub-basin in the Northern Territory.
The company has drilled up to a total measured depth of 4,857 metres, with the horizontal section once again intersecting over 1,000 metres of Mid-Velkerri ‘B’ shale.
Results are consistent with Tamboran’s T2H well, with both wells set to be fracture stimulated and flow tested with initial results expected by the end of 2021.
“Strong gas shows”
Tamboran managing director and CEO Joel Riddle said: “The drilling information gained from T2H and T3H supports our pre-drill understanding that natural fractures are present at this location, the deepest part of the core Beetaloo Sub-basin.
“Coupled with strong gas shows encountered during drilling, we are confident the wells have intersected shale that will respond positively to fracture stimulation.
“Casing in T3H will be set and cemented shortly.”
Drill program
The T3H well, situated in EP 161 and operated by Tamboran''s joint venture partner Santos QNT Pty Ltd, was successfully drilled to a total measured depth of 4,857 metres.
Santos, the operator of EP 161 (75% working interest) and Tamboran (25% working interest) spudded the T3H well on August 23, 2021.
Notably, drilling time in the T3H vertical and build section was reduced by 20% due to learnings from T2H.
The mud gas response logged and encountered within the Mid-Velkerri ‘B’ shale in T3H is consistent with data collected in the Tanumbirini 1 and T2H wells.
Forward plan
Riddle adds: “The release of Easternwell Rig 106 after casing operations on the T3H well will represent the completion of our 2021 drilling program.
"Both wells will now be re-entered, fracture stimulated and flow tested with initial results expected to be announced by the end of 2021.
“The information gained from drilling and flow testing T2H and T3H will be incorporated into the well design for Maverick 1H, the well that Tamboran intends to drill in EP 136, its 100% owned and operated permit, in 2022.”
