Highlights

  • Bunian-6 drilling identified an additional M-sand oil-bearing interval during 2026.
  • Flow testing produced encouraging initial rates, but short tests do not establish sustained field output.
  • Bass reported a first-half profit alongside positive EBITDA and a debt-free cash position.
  • Vanessa and Kiwi form part of the company’s proposed Australian gas expansion.

Bass Oil Limited (ASX:BAS) is an oil and gas producer with producing assets in Indonesia and South Australia and additional Australian gas development interests. Its 2026 updates have focused on the Bunian-6 development well in Indonesia, the prospect of higher output from the Tangai-Sukananti operation and opportunities to develop gas supply on Australia’s east coast.

Bunian-6 Adds Another Producing Interval

On 26 August 2026, Bass reported oil-bearing intervals in the TRM3 and K1 reservoirs at Bunian-6. Additional analysis subsequently identified oil in the M sandstone, a zone that had not been part of the original two-zone interpretation.

No water was recovered during that test, according to the source announcement described in the supplied material. However, test performance is not equivalent to sustained commercial production.

Production Targets and the Indonesian Interest

Bass holds a 55% interest in the Tangai-Sukananti operation in South Sumatra. Its earlier development objective was to lift gross field production from approximately 250 barrels per day to at least 750 barrels per day, with the company’s corresponding share increasing from around 140 to 410 barrels per day.

The company also presented an internal P50 recovery estimate of approximately 151,000 barrels for the discovery. A P50 figure reflects an estimate with a 50% probability of being exceeded, not a reserve of oil already produced.

Half-Year Financial Performance

For the six months ended 30 June 2026, Bass reported revenue of AUD 3.79 million, EBITDA of AUD 1.03 million and net profit after tax of AUD 0.28 million. The supplied report compares that result with a previous-period net loss of AUD 0.14 million and indicates that EBITDA increased by 80.6%.

At period end, cash was reported at AUD 3.18 million with no debt. These figures provide context for the resources available to pursue field work, although they do not establish that all planned spending can be met without additional funding.

Australian Gas Development Remains a Separate Workstream

Bass completed the Vanessa gas field and facility acquisition in June 2026, positioning itself to investigate a route into Australia’s east coast gas market. It has also progressed the Kiwi gas project in South Australia, with development and funding decisions remaining significant steps.

Gas commercialisation will require technical work, appropriate infrastructure, funding and market arrangements. Bass Oil (ASX:BAS) has described opportunities in its Australian portfolio, but prospective output should not be confused with contracted gas sales or operating cash flow.

What to Watch

The most useful measures of progress are subsequent Bunian-6 operating reports, gross and net production at Tangai-Sukananti, realised oil prices and changes in costs. The September-quarter activities report and later company disclosures will also help clarify the timing and capital needs of the Australian gas projects.

The supplied draft recorded an intraday share-price figure, but also identified conflicting trading-status information and no verified same-day catalyst. For that reason, no causal explanation for a daily share movement is asserted here. Any assessment of Bass Oil (ASX:BAS) should distinguish a trading snapshot from a confirmed exchange closing price.

Key Insights

Bunian-6 provides a possible near-term production catalyst, supported by reported first-half profitability. Sustained flow performance, dependable field output and funding decisions for Australian gas remain the main unresolved operating questions.
