Tamboran completes T3H vertical section

Operations at EP 161 for T3H

Tamboran Resources has announced that the vertical section on EP 161 Tanumbirini 3H (T3H), in the Northern Territory, is complete, with drilling of the horizontal section to commence shortly. 

The vertical well and build section was completed at around 3,760 m after encountering the target Mid-Velkerri ‘B’ shale, in line with pre-drilling expectations. 

According to Tamboran managing director and chief executive officer Joel Riddle, the drilling time of the vertical and build section was reduced by 20 per cent due to learnings from Tanumbirini 2H. 

 “The learnings and knowledge gained by the recent T2H well have resulted in a considerable improvement in drilling efficiencies for T3H,” Riddle said. 

“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.” 

Drilling of around 1,000 m of horizontal section will commence once the casing has been run and cemented and the final angle build to 90 degrees is achieved. 

T3H is anticipated to reach total depth at 4,900 m by the end of October. 

After the completion of T3H, the rig will demobilise from the EP 161 permit and a fracture stimulation operation will be conducted on both the T2H and T3H wells. 

Preliminary test flow results from both wells are anticipated to be available by the end of the year. 

Santos operates EP 161 with a 75 per cent working interest, while Tamboran holds 25 per cent.

Tamboran spudded the T3H well on 23 August.
