Beetaloo Energy’s Carpentaria-5H Delivers Stable 6.9 TJ/Day in 30-Day Flow Test

Carpentaria-5H Sustains Strong Gas Flow Rates

Beetaloo Energy (ASX:BTL) has completed a 30-day IP30 flow test on its Carpentaria-5H horizontal shale gas well, achieving an average gas flow rate of 6.9 terajoules per day (TJ/day) with a peak exceeding 14 TJ/day. The well maintained a stable exit rate of 6.7 TJ/day, slightly higher than the 6.3 TJ/day exit rate recorded in the previous test phase, indicating consistent reservoir performance over an extended period.

This sustained production profile bolsters confidence in the quality of the Velkerri Shale at Carpentaria and supports Beetaloo’s previously estimated recoverable gas resource of approximately 10 petajoules (PJ) at the well location. The test's stability across consecutive 30-day periods demonstrates the well’s resilience and potential for long-term gas deliverability.

Extended Cleanup Reduces Water Production

Since hydraulic stimulation completion in July 2025, Carpentaria-5H has undergone a prolonged cleanup phase, reflecting its larger lateral section and higher stimulation fluid intensity compared to earlier wells Carpentaria-2H and 3H. Water production during the IP30 test declined markedly from around 1,300 barrels per day to approximately 440 barrels per day, though it remains elevated relative to the other wells, suggesting ongoing cleanup is still in progress.

This extended flowback period is necessary due to the well’s design, which involved 67 slickwater fracture stimulation stages over a nearly 3-kilometre horizontal section, placing about 11,000 tonnes of proppant. The gradual reduction in water rates alongside stable gas output provides valuable data on reservoir behaviour and completion effectiveness.

Transition to Production and Pilot Project Progress

Following the IP30 testing, Carpentaria-5H has been shut in and will soon be tied in for production alongside Carpentaria-2H and Carpentaria-3H wells. This integration is timed with the anticipated commissioning of the Carpentaria Gas Plant in the fourth quarter of 2026, marking a significant milestone as Beetaloo advances from exploration towards commercial gas production.

Managing Director Alex Underwood highlighted the importance of these results, noting that the well’s stable performance strengthens confidence in the Velkerri Shale’s quality and the company’s recoverable gas estimates. As the Carpentaria Pilot Project moves closer to first gas sales, these developments are critical for converting resource potential into shareholder value.

Reservoir Composition and Testing Details

The Carpentaria-5H well tested the B Shale of the Velkerri Formation at depths between 1,595 and 1,626 metres true vertical depth. Gas composition analysis showed a high-calorific mix dominated by methane (82.77%) and ethane (12.25%), with minor heavier hydrocarbons and inert gases. Wellhead pressures ranged from approximately 1,380 psig to 240 psig during the 30-day test, with choke sizes adjusted between 56/64” and 80/64” to manage flow rates.

These technical results provide a foundation for future development planning and support Beetaloo’s strategy to scale production in the Beetaloo Sub-basin, where it holds a 100% working interest and operatorship in the Carpentaria-5H well.
