Why Did D3 Energy’s RBD10 Well Boost Gas Flow by 39% After Shut-In?
D3 Energy has reported a significant 39% increase in gas flow rates at its RBD10 well in South Africa following a re-test, highlighting strong reservoir recharge and connectivity.
- RBD10 well flow rate averages 276 Mscfd over 6.9 days
- 39% increase compared to initial 2024 testing
- Unusual pressure rise indicates reservoir recharge from deeper source rocks
- Testing ongoing with further pressure analysis planned
- ER315 permit remains a key asset for D3 Energy’s helium and methane production
Strong Reservoir Signals from RBD10
D3 Energy Limited (ASX, D3E) has delivered encouraging results from its RBD10 well, part of the ER315 permit in South Africa’s Free State Province. After a period of being shut in, the well was re-tested and demonstrated a 39% increase in average gas flow rate compared to its initial test in 2024. The recent 6.9-day flow test recorded an average of 276 million standard cubic feet per day (Mscfd), up from 199 Mscfd previously.
Unusual Pressure Trends Suggest Recharge
What makes these results particularly noteworthy is the unusual pressure trend observed during the shut-in period. Instead of declining, reservoir pressure increased beyond initial levels, a rare phenomenon that suggests active recharge from source rocks beneath the reservoir. This connectivity was also observed in other wells within the permit, reinforcing the potential for sustained production.
Implications for ER315 and Broader Strategy
The ER315 permit, operated through D3 Energy’s subsidiary Motuoane Energy Pty Ltd, is a cornerstone of the company’s helium and methane exploration efforts. These improved flow rates and reservoir dynamics could enhance the project’s commercial viability, supporting D3 Energy’s positioning in the global energy transition, particularly in critical gases like helium.
Moreover, the company’s recent expansion into Australia’s Arckaringa Basin complements its South African operations, broadening its resource base and strategic footprint in helium and hydrogen markets.
Next Steps in Testing and Analysis
The current testing phase at RBD10 will continue for another week before the well is shut in again to analyze pressure buildup data. This next phase will be critical to understanding reservoir behavior and refining production forecasts. Investors and analysts will be watching closely for updates that could influence D3 Energy’s development timeline and financing plans.
Bottom Line?
D3 Energy’s RBD10 re-test underscores promising reservoir dynamics, but further data will be key to confirming long-term production potential.
Questions in the middle?
- Will the ongoing pressure buildup analysis confirm sustained reservoir recharge?
- How might these improved flow rates impact D3 Energy’s production forecasts and valuation?
- What are the implications for development timelines and potential financing needs?
