Highlights

  • Buru Energy (ASX:BRU) announced maiden proven and Probable Reserves for the Rafael gas and condensate field.
  • The reserves milestone provides further definition of the project’s commercial development pathway.
  • Rafael remains central to Buru’s growth strategy, with first gas targeted for 2028.
  • Investors are monitoring funding, offtake arrangements and progress towards a final Investment decision.

Rafael has been a discovery for several years without being classified as a reserve. That distinction is important, as contingent resources describe discovered Hydrocarbons while proven and probable reserves represent volumes considered commercially recoverable under defined development assumptions.

Buru Energy has now booked maiden 1P and 2P reserves for the Rafael gas and condensate field, marking an important step as the company progresses towards potential development.

Latest Development

Buru Energy lodged its maiden proven and probable reserves statement for the Rafael gas and condensate field in September 2026, following a Trading halt on 8 September 2026.

Reserves classification requires confidence not only in the presence of hydrocarbons but also in the development concept, commercial pathway and market opportunity.

The reserves statement provides additional project definition as Buru evaluates the next stages of Rafael development.

Company Overview

Buru Energy is a Perth-based onshore energy company focused on the Canning Basin in Western Australia’s Kimberley region.

The company holds more than 22,500 square kilometres of permits, with working interests ranging from 60% to 100%.

Its key Assets include the Rafael gas and condensate discovery and the Ungani oilfield.

Rafael is a wet gas discovery containing gas, condensate and liquefied petroleum gas and represents the company’s main growth opportunity.

The Ungani oilfield, held at 100%, is a legacy producing asset that has been under care and maintenance since August 2023.

Buru also holds non-hydrocarbon interests, including the GeoVault carbon capture and storage concept.

Recent Developments

Buru has partnered with Clean Energy Fuels Australia (CEFA), under which CEFA would finance and operate Midstream infrastructure while Buru retains 100% ownership of the Upstream interest.

The arrangement is designed to reduce Buru’s direct Capital requirements for infrastructure development.

Engineering optimisation work identified additional liquids and LPG streams that were not previously included, increasing indicative annual pre-tax Cash Flow by 20% to 47% compared with 2025 screening estimates.

The updated modelling expanded the internal rate of return range to 42% to 80%.

The development schedule has also evolved, with Rafael 2H verification, appraisal drilling and Rafael 1 recompletion planned for the June quarter of 2027, while first gas is targeted for 2028.

At Ungani, an independent reservoir engineering review announced on 19 August 2026 increased 2C contingent resources to 660,000 barrels from 220,000 barrels.

The company is also assessing a micro-refinery concept aimed at supplying regional diesel Demand instead of transporting crude more than 1,000 kilometres to Wyndham.

Financial and Operational Position

Buru completed a two-tranche institutional placement, raising A$5.3 million through approximately 355 million shares issued at A$0.015 each.

The Placement included one free option for every two shares, exercisable at A$0.022 over three years.

Approximately A$1.3 million was allocated towards Working Capital and offer costs, with the remaining funds directed towards pre-final investment decision activities.

Buru lodged its 2026 half-year financial report on 7 September 2026.

What Investors May Watch Next

The maiden reserves booking moves Rafael closer towards a potential final investment decision.

Key areas for investors to monitor include the project funding structure, offtake arrangements, 2027 appraisal activities and Rafael recompletion work.

Progress on the Ungani restart assessment and the micro-refinery concept will also remain separate areas of interest.

Risks

Reserve estimates remain subject to technical assumptions and may be revised as further information becomes available.

Rafael’s first gas timeline has shifted to 2028, and additional delays remain possible.

Developing a gas project requires significant capital, creating potential funding and dilution considerations.

The CEFA arrangement remains dependent on execution, while remote Kimberley operations present cost, logistics and infrastructure challenges.

Conclusion

The maiden proven and probable reserves classification moves Rafael from a discovered resource towards a defined commercially recoverable asset.

While the milestone strengthens Buru Energy’s development case, it does not remove the need for funding, approvals and execution before production can begin.

For investors following ASX:BRU, the next focus will be whether a reserves-backed Rafael project can secure the capital and commercial arrangements required to progress towards first gas in 2028.
