Lakes Blue Energy has progressed production testing at its Wombat-5 gas well, confirming multi-zone gas flow and entering a critical pressure build-up phase ahead of planned well stimulation. The company also advances regulatory preparations for drilling at its Portland Energy Project, while strengthening its technical team.

Wombat-5 Testing Progresses Toward Commercial Evaluation
Lakes Blue Energy (ASX:LKO) has moved its Wombat-5 appraisal well into the pressure build-up and data acquisition phase, a pivotal step in assessing reservoir performance. Gas flow has been confirmed from all three principal gas sand packages intersected by the well, supporting the presence of multiple productive zones. This follows a series of initial flow, clean-up, and fluid recovery operations that have provided encouraging reservoir pressure responses.
The testing program, designed as a staged sequence, has revealed the need for additional well optimisation. As a result, Lakes plans to undertake a perforation and propellant enhancement program across the horizontal section to boost gas flow, with potential acid washing also under consideration. These activities are subject to regulatory approval and expected to occur within the next two months. The company’s approach aligns with conventional techniques for wells of this nature and aims to advance Wombat toward potential commercialisation within its Victorian gas portfolio.
The significance of these developments is underscored by the well’s confirmation of gas contribution from all zones, including the lowest interval below the sliding sleeve. This multi-zone productivity could enhance the field’s overall resource potential. The phased testing and optimisation strategy follows the company’s earlier decision to pause flow and clean-up activities to focus on pressure analysis, as detailed in the previous quarter’s suspension of well flow and equipment demobilisation. This measured approach reflects the complexities of tight gas reservoirs and the need for detailed reservoir characterisation prior to commercial decisions.
Portland Energy Project Advances Toward Drilling
Alongside Wombat, Lakes is progressing its Portland Energy Project in Victoria’s Otway Basin, where it holds 100% interest and operatorship. The project targets the Eumeralla Formation, an unconventional gas play with a P50 prospective resource estimated by SRK Consulting at approximately 11 trillion cubic feet recoverable gas. The company is refining well locations through reprocessing of 2D seismic data and advancing regulatory, environmental, and stakeholder engagement activities in preparation for drilling.
Planning is underway for up to two proof-of-concept wells in the second half of 2026, contingent on regulatory approvals and portfolio priorities. This drilling program aims to evaluate gas mobility and deliverability within the Eumeralla Formation and possibly the Waarre Sandstone, a conventional reservoir. The Portland Energy Project represents a key longer-term growth opportunity, offering exposure to a large, under-explored Victorian gas system that complements Lakes’ existing assets.
Nangwarry CO₂ Project Feasibility Study Continues
In South Australia’s Otway Basin, the Nangwarry CO₂ Project remains a strategic part of Lakes’ portfolio, focusing on a naturally occurring high-purity CO₂ resource. Under a collaboration with Maison Group Pty Ltd, technical and commercial evaluations are ongoing, including a feasibility study for a 100 tonnes per day plant aimed at reducing operational and capital costs. This project offers exposure to industrial gas markets distinct from Lakes’ natural gas ventures and is being advanced in line with study outcomes and broader company priorities.
Strengthened Technical Team and Financial Position
Reflecting its transition into more advanced appraisal and development phases, Lakes has expanded its exploration and operations team to four technical personnel. Notably, Michael McGowan joined as General Manager of Operations in January 2026, bringing over 35 years of international upstream oil and gas experience. Additional hires include geoscientist Lucas McLean-Hodgson and petroleum engineer John Mackintosh, whose combined expertise enhances the company’s reservoir engineering, geophysics, and field operations capabilities.
Financially, Lakes reported $1.74 million in operating expenditures during the quarter, including $1.34 million on exploration and evaluation. Cash reserves stood at $3.95 million at quarter-end, providing a runway of approximately 2.3 quarters at current burn rates. This funding supports ongoing testing, exploration, and preparatory activities across the portfolio.
The company’s strategic focus on operational capability and disciplined technical evaluation positions it to navigate the complexities of onshore gas development. The staged approach at Wombat, combined with advancing drilling plans at Portland and ongoing CO₂ project assessments, underscores a diversified growth pathway within the Victorian and South Australian energy landscapes.
These developments build on the company’s recent operational milestones, including the completion of Wombat-5 drilling and earlier phases of production testing, as chronicled in prior reports such as the Wombat-5 flow suspension and pressure build-up phase and the commencement of Wombat-5 production testing. The company’s ability to translate these technical advances into commercial outcomes will be a key watchpoint for investors and market observers.
Bottom Line?
Lakes Blue Energy’s methodical testing and team expansion lay groundwork for commercialisation, but regulatory and technical hurdles remain ahead.
Questions in the middle?
- Will regulatory approvals for Wombat-5 stimulation and Portland drilling be secured on schedule?
- How will the planned perforation and stimulation activities impact gas flow rates and commercial viability at Wombat?
- Can the Nangwarry CO₂ Project achieve cost reductions sufficient to support industrial gas market entry?
