Highlights
- EP 161 Tanumbirini 3H (“T3H”) vertical well and build section was completed at approximately 3,760 metres after encountering the target Mid-Velkerri ‘B’ shale.
- Drilling time in the T3H vertical and build section was reduced by 20% due to learnings from Tanumbirini 2H (“T2H”).
- Drilling of the approximately 1,000 metre horizontal section in the Mid-Velkerri ‘B’ shale target will commence shortly with the well is anticipated to reach total depth (TD) by the end of October.
- T2H and T3H wells are planned to be fracture stimulated and flow tested prior to the end of calendar year 2021.
Current Operations
Santos QNT Pty Ltd, the operator of EP 161 (75% working interest) and Tamboran (25% working interest)
spudded the T3H well on 23 August 2021. Drilling of the vertical hole and build section was completed at
the target depth of approximately 3,760 metres after encountering the Mid-Velkerri ‘B’ shale in line with pre-drill expectations. T3H drilling performance improvements through the vertical section resulted in a 20% reduction in the drilling time at T3H in the vertical and build section to a similar depth as 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. Drilling of the approximately 1,000 metre horizontal section will commence once the 7” casing has been run and cemented and the final angle build to 90 degrees is achieved.
Forward Plan
T3H is anticipated to reach TD at approximately 4,900 metres depth by the end of October. After the completion of T3H, the rig will demobilise from the EP 161 location and a fracture stimulation operation will be conducted on the T2H and T3H wells. Preliminary flow test results from both wells are anticipated to be
available prior to the end of calendar year 2021.
Tamboran Resources Limited (ASX: TBN) Managing Director and CEO, Joel Riddle, said:
“Similar to our experience in other unconventional shale basins in the US, the learnings and knowledge gained by the recent T2H well have resulted in a considerable improvement in drilling efficiencies for T3H. Our operations team will incorporate these valuable learnings and information from the T2H and T3H wells
into the well design for our Maverick 1H well, which Tamboran plans to drill on EP 136, our 100% owned and operated permit, in 2022.”
