Highlights
- D3 Energy reports a 35% boost in gas flow at RBD03 well
- Expansion underway with new permits in Arckaringa Basin
- Stronger prospects align with helium-hydrogen exploration drive
D3 Energy Ltd (ASX:D3E) has reported a notable increase in production at its RBD03 gas well in South Africa, signaling operational momentum as it simultaneously expands its footprint into Australia’s promising helium and hydrogen territories.
Stronger Gas Flow at South African Well
The RBD03 well, originally drilled in 1982, is part of D3 Energy's broader production testing strategy within the ER315 permit in South Africa’s Free State region. A recent workover operation conducted on May 7, 2025, successfully removed legacy borehole obstructions. Although some limitations were encountered due to undocumented hole size variations, the intervention paved the way for retesting.
Testing resumed on June 13, 2025, and the well delivered a 35% increase in gas flow, reaching an average of 201 Mscfd over a seven-day period—an improvement from the earlier 149 Mscfd. In total, 1,396 Mscf of gas was produced during the test window. Testing will continue for another week before a pressure build-up analysis is conducted.
This performance update adds confidence to D3 Energy’s operational capabilities in a region with long-standing gas potential, while also setting the stage for more consistent output in future development stages.
Strategic Entry into Australia’s Emerging Helium-Hydrogen Corridor
In parallel with its success in South Africa, D3 Energy recently announced its acquisition of two exploration permits in South Australia's Arckaringa Basin—an area spanning approximately 80,000 square kilometres. This region is one of the least explored zones within the country’s emerging helium and hydrogen corridor, making it an attractive opportunity for forward-looking energy ventures.
Geological similarities between the Arckaringa Basin and the adjacent Amadeus Basin strengthen the strategic rationale behind this move. Notably, the Mt Kitty-1 and Magee-1 wells in the Amadeus region revealed high levels of helium (up to 9%) and hydrogen (up to 11.5%), indicating untapped sub-salt potential. These results offer a promising geological framework that D3 Energy aims to leverage in the Arckaringa Basin.
Future Prospects and Market Context
This dual-pronged operational update—enhanced output in South Africa and new exploration in Australia—comes at a time when resource companies are seeking cleaner and high-value gas alternatives like helium and hydrogen. It also aligns with broader interest in energy transition assets and growth themes visible on indices such as ASX200.
With solid testing results and new exploration acreage in hand, D3 Energy is positioning itself as a key participant in the next wave of sustainable energy development.
