Highlights

  • Record daily gas production of approximately 570m³ was achieved in December 2025 at the Gurvantes Project.
  • Average daily gas output rose 13% month-on-month to around 526m³ per day, marking the fifth consecutive monthly increase.
  • Gas production in December exceeded four times the level recorded in August 2025, with wells operating above 99% uptime.

TMK Energy Limited (ASX:TMK) has reported its fifth consecutive month of increasing gas production at the 100% owned Gurvantes XXXV Coal Seam Gas Project in Mongolia. December 2025 delivered record daily and monthly production levels, marking continued progress from the company’s Pilot Well Project.

New Daily Gas Production Record

A new daily gas production high of approximately 570 cubic metres per day, equivalent to more than 20,100 standard cubic feet per day (scfd), was achieved on 30 December 2025. Production levels remained at or near this rate through the end of the year, representing the first time daily output has exceeded the 20,000 scfd threshold at the Gurvantes project.

This milestone extends a sequence of increasing gas rates recorded each month since August 2025, with all producing wells operating at greater than 99% uptime during the period.

December Output Shows Month-on-Month Increase

Average daily gas production during December reached approximately 526 cubic metres per day, representing a 13% increase from November’s average of around 466 cubic metres per day, which had previously set a monthly record.

Total gas produced for December amounted to 16,306 cubic metres, compared with 13,981 cubic metres in November. Since August 2025, gas production has increased more than fourfold, reflecting ongoing improvements in well performance across the pilot area.

Water production remained steady throughout the month, averaging 511 barrels of water per day, indicating stable reservoir conditions during the continued ramp-up of gas output.

Pilot Wells Move Toward Integration

Engineering and planning activities are underway to configure the pilot wells so gas production can be combined across the field. The work is focused on enabling the gas to be utilised on-site for power generation, with the potential for excess electricity to be supplied into the local power grid.

This configuration is expected to support continued testing of the reservoir and infrastructure performance while advancing the project toward practical utilisation of produced gas.

Focus Shifts to Commercial Pathways

With consistent increases in production rates recorded over consecutive months, the Pilot Well Project continues to progress toward key operational benchmarks. The sustained rise in output indicates ongoing pressure reduction within the coal seams, a critical step in coal seam gas development.

Planning for 2026 is centred on advancing commercialisation pathways for the Gurvantes resource as gas production continues to scale from the pilot program.
