West Erregulla Gas

The Erregulla gas fields are situated within the Perth Basin, Mid-West region of Western Australia, in the South West Mining Field district. The terrain is characterised by flat to gently undulating semi-arid plains, typical of the northern Perth Basin's onshore stratigraphy. Surface conditions present low topographic relief, which simplifies pad construction and heavy equipment mobilisation. However, shallow aquifer sensitivity and sandy alluvial soils demand rigorous civil engineering controls during well pad earthworks and access road construction to prevent subsurface contamination and structural instability.

Erregulla operates under a FIFO rotational roster model, with personnel mobilised primarily from Perth Airport (PER). The asset is in active appraisal-to-development transition, requiring sustained B2B engagement across:

• Drilling and completions contractors for deep tight-gas well programs
• Wellsite accommodation and camp logistics providers
• Specialist wireline, coiled tubing, and stimulation service vendors
• Pipeline and gas processing infrastructure EPC contractors

Geraldton serves as the nearest regional supply hub for consumables and crew rotation staging.

Erregulla targets the Kingia and High Cliff Sandstone formations at depths exceeding 3,500 metres, requiring high-pressure hydraulic fracture stimulation. Key engineering parameters include:

• Directional and horizontal well drilling with multi-stage frac completions
• High-specification wellhead pressure management systems
• Modular gas processing and dehydration units at surface
• Pipeline tie-in infrastructure targeting the DBNGP (Dampier to Bunbury Natural Gas Pipeline)

No conventional milling or flotation circuits apply; extraction is purely petroleum-phase subsurface engineering.

Strike Energy positions Erregulla within a domestic gas supply decarbonisation narrative, targeting displacement of higher-emission coal-fired generation in Western Australia's SWIS grid. ESG commitments include:

• Environmental approvals process led by a dedicated Environmental Approvals Lead (Stephen Lloyd)
• Groundwater and surface impact monitoring under WA DER/DWER regulatory frameworks
• Alignment with WA Government's domestic gas reservation policy
• Scope 1 emissions reduction through lean-burn gas engine selection for compression facilities

Renewable energy integration at wellsite level remains under evaluation for future development phases.
