TMK Energy Breaks Gas Production Records at Gurvantes XXXV
TMK Energy has set new daily gas production records at its Gurvantes XXXV Coal Seam Gas Project, with November averages rising 18% over October and further gains in December. The company also completed its 2025 exploration program, confirming promising coal seam extensions.
- Record daily gas production of 527m³ on 14 November
- November average gas production up 18% from October
- Stable water production supports reservoir pressure decline
- 2025 exploration program completed with key coal seam findings
- Planning underway for 2026 drilling to accelerate gas output
Record Production Milestone
TMK Energy Limited (ASX – TMK) has announced a significant operational milestone at its 100% owned Gurvantes XXXV Coal Seam Gas Project, achieving a new daily gas production record of 527 cubic metres on 14 November 2025. This peak is part of a broader trend, with November’s average daily gas production rising approximately 18% to 466 cubic metres compared to October’s record average of 395 cubic metres.
Since the start of December, production rates have continued to climb, averaging around 509 cubic metres per day, indicating sustained momentum in output growth.
Reservoir Management Driving Efficiency
The company attributes these gains to its revised reservoir management plan (RMP), which has been instrumental in reducing downtime and maintaining stable water production, averaging 493 barrels per day in November. Stable water extraction is critical as it helps reduce reservoir pressure, a necessary condition to reach the critical desorption pressure where gas release accelerates.
Importantly, the project has experienced no pump blockages since implementing the revised RMP, significantly cutting operational interruptions and costs. A planned four-day shut-in of well LF-06 in November confirmed ongoing reservoir pressure decline, a positive sign for future gas recovery.
Exploration Program Completion and Future Plans
In November, TMK completed its 2025 exploration program, fulfilling license agreement commitments. Two wells drilled east of the pilot project intersected thick coal seams, extending the known coal seam play fairway. Although gas content was lower in these shallower coals, the data is guiding future drilling to target deeper, more gas-rich seams.
A third well within the pilot area focused on validating gas content data, with core samples now undergoing detailed testing expected to conclude in Q1 2026. These results will be crucial to confirming reservoir quality and informing the next phase of development.
With reservoir simulation modelling providing clear insights, TMK is already planning a 2026 drilling program aimed at accelerating and increasing gas production, leveraging the knowledge gained from recent exploration and operational improvements.
Outlook
CEO Dougal Ferguson highlighted the positive trajectory – “Four successive months of increasing gas production, stable water rates, and no workovers demonstrate the effectiveness of our revised reservoir management plan. The exploration program has expanded our understanding of the resource, setting the stage for growth in 2026.”
As TMK advances toward critical desorption pressure, the coming months will be pivotal in translating operational gains into sustained commercial production increases.
Bottom Line?
TMK’s steady production gains and exploration success position it well for accelerated growth in 2026, but upcoming gas content test results will be key to confirming reservoir potential.
Questions in the middle?
- Will the Q1 2026 gas content testing validate the reservoir’s commercial viability?
- How aggressively will TMK pursue its 2026 drilling program based on current reservoir models?
- What impact will stable water production have on long-term operational costs and output?
