Santos, Tamboran spud final Tanumbirini well

State Gas well starts production test

Tamboran Resources, on behalf of its joint venture partner Santos, has spudded the Tanumbirini 3H well (T3H) in the Beetaloo Basin, Northern Territory.

The drilling of the surface vertical hole section was completed at a depth of 1080m and drilling in the intermediate vertical section is currently ahead of schedule.

Tamboran managing director and chief executive officer Joel Riddle said once it has completed the drilling of the vertical and angle build section to the primary target of the Mid-Velkerri B shale, Tamboran plans to drill a horizontal section of 1000m.

“Similar to our experience in other unconventional shale basins in the US, the learnings and knowledge gained by the recent T2H well are playing a considerable role in improving drilling efficiencies and reducing costs,” he said.

“Following the drilling of the T3H horizontal section, both T2H and T3H wells will be fracture stimulated and flow tested, with results expected to be available prior to year-end 2021. Our team will incorporate the learnings and information from T2H and T3H into the well design for Maverick 1H, the well that Tamboran intends to drill in EP 136, its 100 per cent owned and operated permit, in 2022.”

In July the joint venture completed drilling the vertical hole and build section of the T2H well, which the vertical well and build section completed at 3800m target depth after encountering the Mid-Velkerri B shale.

Preliminary flow tests results from T2H and T3H are set to be available from the fourth quarter of this year.

Subject to final approvals, the company intends to acquire seismic on EP 136 in the second half of 2021 and, based on information gained from this and the EP 161 drilling program, will be in an position to drill its first operated well in 2022.
