Australian Oil Company Limited has announced a comprehensive reinstatement strategy for its Surat Basin assets, marking a significant step to enhance production capacity and streamline its asset portfolio amid shifting market dynamics.
Key Points
- Australian Oil Company Limited (ASX:AOK)
- Initiation of Phase 1 development activities in the Surat Basin
- Emphasis on reinstating Major Gas Field, Riverslea-3, and Emu Apple Oil Field
- Investors advised to monitor progress on resource mapping and commercial gas sales negotiations
Surat Basin Phase 1 Development Progresses
Australian Oil Company Limited has commenced Phase 1 of its development projects in Queensland's Surat Basin, where it holds a 100% working interest. This region is targeted due to its underexplored, high-quality oil and gas prospects. The company’s development plan centers on a phased reinstatement approach, starting with the Major Gas Field, then advancing to Riverslea-3 and the Emu Apple Oil Field.
The strategy focuses on maximizing production efficiency and utilizing existing infrastructure. Prioritizing the Major Gas Field reflects its suitability for cyclical reinstatement and the current favorable gas pricing environment. This aligns with Australian Oil’s goal to address east coast gas supply challenges and capitalize on emerging market opportunities.
Major Gas Field: Central to Reinstatement Efforts
Located within PL 512, the Major Gas Field is the initial asset in the Surat Basin reinstatement plan. Historically, it has yielded approximately 4.5 billion cubic feet of gas. Recent evaluations suggest further development potential, with geological mapping and resource assessments nearing completion and identifying upside opportunities.
Commercial gas sales discussions are advancing to support near-term development. The PPL 22 pipeline, linking to the Silver Springs Gas Plant, remains in good condition, negating the need for new infrastructure. Engineering studies are underway to reconnect gas to the Boxley pipeline and to evaluate operating strategies for reinstating Major-4, a well positioned near the gas-water contact.
Emu Apple Oil Field: Intervention and Production Status
The Emu Apple Oil Field, under PL 264, recently underwent intervention to enhance production. Two liftings totaling 844 barrels were completed in late March and early April 2026, averaging around $151 per barrel. Following an acid and condensate intervention, the well is currently shut-in to optimize treatment before resuming operations.
New exploration targets north of the field have been identified, with anomalies indicating additional potential. The field’s renewal application (APL 1170) is currently under regulatory review, which may influence future development timelines. Investors should watch for updates on the field’s restart and regulatory outcomes.
Riverslea and Yapunyah Fields: Updated Restart Strategy
The Riverslea and Yapunyah fields, included in PL 30, have a revised restart plan focusing initially on Riverslea-3. Historically, these fields produced 564,000 barrels with test rates between 15-17 barrels of oil per day. The company intends to restart Riverslea-3 using a free-flow approach, followed by evaluation of artificial lift options.
Crude assays are being conducted with IOR to support an offtake agreement. Future plans include restarting Riverslea-1 and pursuing step-out drilling at Yapunyah, aiming to boost production and align with Australian Oil’s broader regional strategy.
California Operations: Efficiency Enhancements and Outlook
In addition to Surat Basin activities, Australian Oil operates natural gas assets in California’s Sacramento Basin. The company has implemented cost-saving and efficiency initiatives across assets such as Dempsey, Malton, Rio Vista, and Dutch Slough.
Plans are underway to bring Rec Board Wells back online within roughly two months, contingent on PG&E pipeline maintenance. Ongoing discussions with CRC regarding VBC and Malton well integration highlight potential for growth and operational synergies in this secondary focus area.
Experienced Leadership Driving Strategic Growth
Australian Oil’s leadership team, including Managing Director Kane Marshall and Non-Executive Directors Piers Lewis and Bill Ashby, brings extensive industry expertise. Supported by specialists in exploration, development, and frontier exploration, the team is well-positioned to execute the company’s growth strategy.
The company remains committed to exploring new venture opportunities beyond its core regions, aiming to capitalize on underexplored markets and enhance shareholder value through focused development efforts.
Market Environment and Future Prospects
The energy sector continues to experience volatile oil and gas prices, influencing operational approaches. Australian Oil’s emphasis on optimizing its asset base and leveraging existing infrastructure positions it to effectively manage these market challenges.
Investors should monitor updates on resource mapping completion, commercial gas sales progress, and regulatory decisions affecting Surat Basin assets, as these will significantly impact the company’s growth trajectory.
Investor Risks and Considerations
Despite strategic progress, investors should consider risks including regulatory approvals, market volatility, and operational uncertainties. Dependence on existing infrastructure and partnerships also presents potential vulnerabilities.
Prospective investors are advised to conduct thorough research and seek independent professional guidance before making investment decisions, ensuring a comprehensive understanding of market conditions and company-specific factors.
