• Odin and Vali gas fields produced 100 MMscf of raw gas in May 2025, 8% higher than April
• Average daily production up 5% from previous month
• Operational measures taken to increase output ahead of Production Uplift Program

Vintage Energy Ltd (ASX: VEN, 'Vintage'), 50% interest-holder and Operator of the PRL 211 and ATP 2021 Joint Ventures, has reported its Southern Flank Gas Fields have recorded their strongest monthly production performance in nearly 6 months. The Odin and Vali gas fields produced 100 MMscf of raw gas in May 2025, 8% higher than the preceding month's comparative of 92 MMscf. Average daily production of 3.23 MMscf was 5% higher than the preceding month's comparative of 3.08 MMscf. Total production from the fields in May were the highest since January 2025 (113 MMscf). The increased output, which occurred counter to natural decline anticipated from depletion, is attributed to operational measures taken in advance of the previously announced Production Uplift Program. The measures taken include back pressure reduction in the gathering system, cycling Odin-2 for pressure build-up and flow, and instrumentation reliability improvements. Production from the Odin gas field rose, with average daily gas production up from 2.30 MMscf/d to 2.47 MMscf/d. Vali recorded a smaller than anticipated decline, with average daily production of 0.76MMscf/d marginally below the April daily average of 0.78MMscf/d. Vintage Energy Managing Director Neil Gibbins said the team has been pursuing initiatives to lift output in advance of the Production Uplift Program, and the results have been pleasing. The Production Uplift Program comprises a range of initiatives at Odin and Vali, including investigation and potential remediation of scale accumulation, opening of additional production intervals in the Toolachee Formation at Vali, and swab and re-perforation at Vali-3. The program has been modelled to provide an uplift in raw gas production of between 2.1 MMscf/d to 5.6 MMscf/d from the company's Odin and Vali gas fields with cash payback of less than three months.

The Production Uplift Program is expected to commence from mid-July and provide an uplift in raw gas production of between 2.1 MMscf/d to 5.6 MMscf/d from the company's Odin and Vali gas fields with cash payback of less than three months.

Vintage Energy is keen to commence the Production Uplift Program for more substantial improvements from both the Odin and Vali gas fields.
