D3 Energy advances multi-well testing at ER315, with latest RBD10 flow rates showing significant uplift
Results support robust reservoir connectivity and feed into the company’s broader helium and methane development strategy
Improved flow rates from RBD03 and RBD10 bolster ongoing reserve certification and production right applications
D3 Energy Ltd (ASX:D3E), listed on the ASX 200, is moving forward with production testing at its flagship ER315 project in South Africa’s Free State. The company has reported a notable performance uplift at its RBD10 well, signalling reservoir recharge and strong geological continuity. The latest results feed into a broader strategy to transition from appraisal to full-scale development across its helium and methane portfolio.
RBD10 Re-Test Yields Encouraging Flow Rates
Re-testing of the RBD10 well commenced following a shut-in period to facilitate pressure buildup and allow testing of other boreholes. The subsequent flow test, which resumed mid-July, has shown a marked improvement in gas output, pointing to favourable subsurface dynamics and potential reservoir recharge from deeper source rocks.
This phase forms part of D3 Energy’s multi-well testing initiative, aimed at verifying productivity and resource quality across legacy wells within the ER315 permit. The response at RBD10 is now under further observation, with additional testing planned over the coming week to validate sustained production capability.
Advancing Strategy Toward Development and Reserve Recognition
The performance at RBD10 builds on recent progress at the RBD03 well, where a clean-out operation resulted in higher flow rates. These advancements contribute directly to D3 Energy’s geological model and support key milestones including reserve certification and the company’s application for a Production Right.
Collaboration with independent consultancy Sproule ERCE has recently culminated in the completion of D3 Energy’s maiden reserve certification for ER315. This development marks a critical step as the company looks to unlock commercial value from its resource base.
Expanding International Presence and Strategic Focus
While ER315 remains the centrepiece of D3 Energy’s operations, the company is broadening its footprint through targeted acquisitions and exploration activity. This includes progress in Australia’s Arckaringa Basin, where D3 Energy is exploring further opportunities across the helium and hydrogen sectors.
The success at RBD10 reinforces D3 Energy’s position in the critical gases landscape. With flow rates supporting the company’s exploration model and reserve strategy, the ER315 project continues to evolve as a key component in its expansion across emerging energy markets.
What is the ER315 project operated by D3 Energy?
The ER315 project is a helium and natural gas development in South Africa’s Free State, serving as D3 Energy’s primary exploration and production asset.
What results have been observed at the RBD10 well?
The RBD10 well showed improved gas flow following a re-test, indicating good reservoir connectivity and recharge from deeper source rocks.
How does the RBD10 performance affect D3 Energy's development plans?
The flow results contribute to reserve certification and support D3 Energy’s transition from appraisal to development at the ER315 project.
