Power Outages and Well Shut-Ins Challenge TMK’s Production Growth Momentum
TMK Energy reports a significant 60% increase in gas production at its Gurvantes XXXV Pilot Well Project in September 2025, driven by improved drilling techniques and strategic reservoir management despite operational challenges.
- 60% rise in gas production at Pilot Well Project in September 2025
- Stable water production maintained at approximately 500 barrels per day
- LF-07 well shows strong gas output at low pump speeds
- LF-02 well continues gas production during shut-in period
- New Operations Superintendent to start in November 2025
Operational Momentum at Gurvantes XXXV
TMK Energy Limited (ASX, TMK) has delivered a robust update on its Pilot Well Project at the Gurvantes XXXV Coal Seam Gas (CSG) site, revealing a 60% increase in gas production during September 2025 compared to the previous month. This surge comes despite some operational hurdles, including unexpected power outages and a planned shut-in of one of its key wells, LF-02.
The company’s reservoir management plan (RMP), designed to optimise well performance by balancing water and gas production while mitigating coal fines that can block pumps, appears to be yielding positive results. Water production remained steady at around 500 barrels per day, a critical indicator for sustaining future gas output.
Encouraging Well Performance and Technical Advances
Among the standout performers, the recently drilled LF-07 well demonstrated strong gas production rates even at low pump speeds, suggesting that updated drilling and production techniques are enhancing initial well productivity. Meanwhile, LF-02, historically one of the best gas producers, was shut in for a few weeks to assess water production improvements and underwent a pressure build-up test. Notably, LF-02 continued to produce gas at approximately 30 cubic metres per day during this shut-in, indicating ongoing coal desorption and promising reservoir behaviour.
These operational insights are being complemented by the engagement of a seasoned coal seam gas reservoir engineer, who is analysing the collected data to refine forecasts for typical well production. This analysis is expected to inform the broader full field development plan, a critical step as TMK moves from pilot operations toward larger-scale production.
Strengthening the Team and Funding Outlook
In a strategic move to support the project’s next phase, TMK has appointed a full-time Operations Superintendent, set to begin on-site in November 2025. This role will be pivotal in implementing rigorous operational processes and safety protocols essential for a maturing gas production operation.
Additionally, the company secured further funding in September, enabling the commencement of its 2025 exploration program. This financial boost underscores TMK’s commitment to advancing its exploration and development activities, setting the stage for continued operational momentum.
CEO Dougal Ferguson highlighted the active month, noting that the pilot wells are performing near record levels and that the company is well-positioned to optimise production through its updated reservoir management approach and enhanced operational oversight.
Bottom Line?
With production gains and strategic hires underway, TMK Energy is poised to translate pilot success into full-scale development.
Questions in the middle?
- How will the upcoming reservoir engineer’s report adjust production forecasts and development plans?
- What impact will the new Operations Superintendent have on operational efficiency and safety?
- How might ongoing power outages and well shut-ins affect short-term production stability?
