Whitebark Energy Launches Comprehensive Warro Gas Field Re-evaluation Studies
Whitebark Energy Limited (ASX: WBE) has announced the commencement of four critical technical and commercial studies on its strategically located Warro Gas Field in Western Australia's Perth Basin. The Whitebark Energy Warro Gas Field studies represent a significant step forward in the company's efforts to unlock the commercial potential of this 7,000-hectare gas asset located just 30 kilometres from the Dampier-to-Bunbury Natural Gas Pipeline.
The studies, enabled by Whitebark's recently completed capital raising, will consolidate and reinterpret the field's substantial legacy dataset to establish a modern, integrated understanding of Warro's reservoir behaviour and commercial viability. Furthermore, with Western Australia's domestic gas market tightening and supply becoming increasingly valuable, the timing of this comprehensive re-evaluation could prove pivotal for the company's growth trajectory.

Understanding Gas Field Commerciality Assessment
A commerciality study evaluates whether a gas discovery can be economically developed into a producing asset. This assessment considers multiple factors including reservoir quality, production rates, development costs, infrastructure requirements, and market conditions.
For Warro, RISC Advisory's evaluation will be particularly valuable given the field's proximity to existing pipeline infrastructure and the current supply-demand dynamics in Western Australia's domestic gas market. In addition, the study will model various development scenarios, from simple tie-ins to more complex field development programmes, providing Whitebark with a clear roadmap for potential monetisation strategies.
Key Components of Commerciality Studies:
- Reservoir Engineering: Assessment of production potential and decline rates
- Economic Modelling: Net present value calculations under various commodity price scenarios
- Infrastructure Requirements: Capital expenditure estimates for field development
- Market Analysis: Evaluation of gas sales opportunities and pricing mechanisms
- Regulatory Framework: Assessment of approval pathways and environmental considerations
Strategic Location Advantage in Tightening Market
| Asset Highlights | Details |
|---|---|
| Field Size | 7,000 hectares |
| Pipeline Distance | 30 kilometres to Dampier-to-Bunbury Pipeline |
| Historical Investment | >$100 million in 3D seismic and drilling |
| Previous Test Results | 1-2 MMscf/d flows confirmed |
| Wells Drilled | 4 vertical wells completed |
Warro's strategic positioning becomes increasingly valuable as Western Australia's domestic gas market tightens. The field's close proximity to major pipeline infrastructure provides a significant competitive advantage, enabling rapid tie-in and delivery to market once commercial production is established.
Previous operators invested over $100 million in exploration and development activities, including 3D seismic surveys and drilling four vertical wells. Consequently, these efforts confirmed a large gas resource with test flows of 1-2 MMscf/d, despite limited reservoir stimulation and high water cut challenges.
The Yarragadee Formation, which hosts the Warro gas field, is a proven gas-bearing reservoir throughout the Perth Basin. Historical production from similar formations in the region demonstrates the commercial viability of these geological structures when properly developed with modern completion techniques.
Near-Term Catalyst Timeline
The integrated study results are expected in the short term, with Whitebark planning to progress to a selective re-completion and re-testing programme if results prove positive. However, the company's approach focuses on:
- Immediate Phase: Completion of four technical studies
- Integration Phase: Synthesis of results into development strategy
- Execution Phase: Targeted re-completion programme focusing on highest-confidence dry-gas intervals
- Production Phase: Commercial gas production targeting Western Australia's domestic market
Management Perspective:
"We are applying the best capability and modern technology to Warro to try and understand what this reservoir is capable of commercially delivering in the long term. We are cautiously optimistic that this work will lead to an asset that has the potential to material change the scale of the Company, however we will let the science guide us." – Nik Sykiotis, COO
Technical Advantages of Modern Interpretation
Whitebark's approach leverages significant technological advances that were not available to previous operators. Furthermore, modern petrophysical analysis techniques, enhanced fracture stimulation methods, and improved completion technologies provide new opportunities to optimise gas recovery whilst minimising water production.
The Whitebark Energy Warro Gas Field studies incorporate these technological improvements to maximise the field's potential. For instance, the borehole image log analysis by Imagestrat will be particularly valuable, as these logs can identify natural fracture networks that may control both gas flow and water inflow.
Key Technical Improvements:
- Advanced Logging: Modern logging tools provide better formation evaluation and fracture identification
- Fracture Stimulation: Regulatory support for enhanced completion techniques in Western Australia
- Water Management: Improved understanding of water-bearing zones enables selective completion strategies
- Reservoir Modelling: 3D geological models incorporate all historical data with modern interpretation methods
Understanding these features is essential for designing completion programmes that maximise gas production whilst controlling water cut.
Investment Thesis: Positioned for Market Transformation
Whitebark's re-evaluation of Warro represents a calculated approach to unlocking significant value from a strategically positioned gas asset. The Whitebark Energy Warro Gas Field studies provide the foundation for this value realisation strategy.
Several factors support the investment case:
Market Dynamics: Western Australia's tightening domestic gas market creates favourable conditions for new supply sources, particularly those with existing infrastructure advantages.
Technical Advancement: Modern interpretation techniques and renewed regulatory support for fracture stimulation provide tools that were not available to previous operators, potentially unlocking previously constrained resources.
Infrastructure Advantage: The field's proximity to the Dampier-to-Bunbury Pipeline eliminates major infrastructure development costs and accelerates potential time-to-market.
Proven Resource Base: Over $100 million in previous investment has confirmed the presence of significant gas resources, with the current studies focused on optimising extraction and commercialisation strategies.

The company's diversified portfolio, including projects in South Australia's Officer Basin alongside the Warro opportunity, provides multiple avenues for growth whilst maintaining focus on high-impact energy assets.
Financial Considerations
The recent capital raising provides Whitebark with sufficient funding to complete the technical studies and potential re-completion programme. This removes near-term funding risk and allows the company to focus on technical execution rather than capital constraints.
Market Context
Western Australia's gas market benefits from strong domestic demand and limited new supply sources. The state's industrial base, including mining operations and LNG processing facilities, provides a stable customer base for domestic gas production.
Investment Takeaway:
Whitebark Energy has positioned itself strategically in Western Australia's tightening gas market with a near-term opportunity to unlock significant value from the Warro Gas Field. With technical studies underway and a clear development pathway emerging, investors should closely monitor the upcoming results that could transform the company's scale and market position.
