Strike Energy’s Walyering West-1 well delivered a stabilised gas flow of 11 MMscf/d from the C1 sand, confirming a clean, condensate-rich gas accumulation near existing infrastructure in the Perth Basin.
- Stabilised flow rate of 11 MMscf/d from C1 sand
- Low CO2 content of 1-2%, matching existing Walyering production
- Higher condensate yield than current field levels
- Potential for development using nearby Walyering facilities
- Further evaluation to update reserves and resources
Strong Gas Flow Validates Walyering West-1 Potential
Strike Energy (ASX:STX) has confirmed a stabilised gas flow rate of 11 million standard cubic feet per day (MMscf/d) from the C1 sand at its Walyering West-1 exploration well in the Perth Basin. The flow test, conducted over 12 days, demonstrated a low-impurity gas stream with CO2 levels between 1-2%, consistent with the company’s existing Walyering production. This result underscores the reservoir’s quality and hints at a promising near-field development opportunity.
Condensate-Rich Gas and Infrastructure Proximity
Notably, the gas condensate ratio during testing was higher than current Walyering field production, with approximately 15 barrels of condensate per million cubic feet of gas. Water production was minimal, at just 1.5 barrels per million cubic feet, indicating favourable reservoir conditions. The well sits roughly 3 kilometres from the Walyering Gas Facility, positioning it well for low-cost commercialisation if reserves are confirmed through ongoing analysis.
Mixed Results from Other Reservoir Sands
Testing of other reservoir intervals yielded varied outcomes. The Asub1 sand flowed at a lower stabilised rate of 2.8 MMscf/d but showed limited reservoir connectivity. The D1 sand failed to produce hydrocarbons at measurable rates, aligning with petrophysical data indicating lower quality. Meanwhile, testing of the D2 to D4 sands was curtailed due to water production, with the D4 sand identified as the likely source. Strike may revisit these zones via recompletion to isolate water-producing intervals and retest the gas-bearing sands.
Reserves and Resources Update Pending Further Analysis
Strike’s Managing Director Shelley Robertson highlighted the test’s implications for expanding gas supply to support existing production and future contracts. The company is integrating pressure transient data and gas composition analyses into its reserves and resources assessments, due with its annual reporting. This flow test follows the well’s successful drilling results announced earlier in April 2026, confirming the presence of a new gas accumulation within the Walyering field area.
Strategic Fit Within Strike’s Perth Basin Portfolio
The Walyering West-1 results arrive amid broader progress at Strike, including the commissioning of the South Erregulla Power Station scheduled for October 2026. The proximity of Walyering West-1 to existing infrastructure could accelerate development timelines compared to greenfield projects, complementing Strike’s strategy to grow near-field gas supplies efficiently. The company’s ongoing evaluation will be closely watched for indications of how this new accumulation might influence production forecasts and reserves growth.
Bottom Line?
Walyering West-1’s clean, condensate-rich gas flow near existing infrastructure opens a pathway for incremental production, but further analysis will determine its commercial scale.
Questions in the middle?
- Will post-test analysis confirm commercially viable reserves to support development decisions?
- Could recompletion of water-bearing sands unlock additional gas volumes in the Walyering West-1 well?
- How might this new accumulation influence Strike’s near-term production guidance and infrastructure utilisation?
