“Results from Tanumbirini flow tests
Modelling of the Tanumbirini flow tests, conducted by independent third-party subsurface experts, Subsurface Dynamics, Inc., demonstrates EURs in-line with Tier 1 and Tier 2 Marcellus Basin acreage in the US. The two wells, which were drilled in the deepest regions of Mid Velkerri “B Shale” in the Beetaloo Basin (true vertical depth of more than 3,400 metres), were deemed to have achieved commercial flow rates in 2022.
The modelling has demonstrated that T3H is capable of delivering a 20-year EUR of approximately 6.1 BCF per 1,000-metrehorizontal section. This implies 20-year EUR per well of approximately 18.5 BCF for a potential 3,000 metres1 Beetaloo Basin development well. Being the first two wells drilled in the deeper ‘Core’ Beetaloo Basin, Tamboran believes that significant improvement in flow rate and EURs can be established with application of learnings to optimise stimulation design.
The T2H and T3H wells achieved 90-day initial production (IP90) flow rates from the Mid Velkerri “B Shale” of 1.6 mmscfd over a 660-metre completed horizontal section (normalised at 2.4 mmscfd over 1,000- metres) and 2.1 mmscfd over a 600-metre completed horizontal section (normalised at 3.5 mmscfd over 1,000-metres) respectively, following the installation of production tubing in August 2022.”
