Key Highlights

  • Weekly pilot production averaged more than 900 cubic metres of gas per day.
  • The latest rate exceeded the August daily average by approximately 11%.
  • Wells LF-02, LF-05 and LF-06 joined LF-07 in recording new output highs.
  • Management is discussing reserve progression and an exploitation licence with Mongolian regulators.

TMK Energy Limited (ASX:TMK) has reported broader production participation across its wholly owned Gurvantes XXXV Pilot Well Project in Mongolia. Average gas output exceeded 900 cubic metres a day, or about 32,000 standard cubic feet a day, during the latest week, while several wells reached their highest recorded rates.

Production Extends across Several Wells

The weekly average stood approximately 11% above the August daily rate. LF-02, LF-05 and LF-06 recorded new highs alongside LF-07, showing that the pilot’s output was no longer concentrated in one leading well. TMK linked the pattern to continuing gas desorption across the field as dewatering and pilot operations progressed.

Pilot Data Builds the Reservoir Picture

Production from the pilot allows TMK to observe how the coal-seam system responds over time before a broader development decision. A weekly average offers a current operating measure, but longer histories are required to evaluate repeatability. Water production, reservoir pressure, well uptime and decline behaviour will also inform modelling and estimates of recoverable gas.

Resource Conversion Requires More Evidence

TMK is preparing its 2026 drilling and recompletion program while maintaining pilot production. Management has been discussing how the project’s 2C contingent resources could progress towards initial reserves and an exploitation licence. Contingent resources are discovered quantities that are not yet considered commercially recoverable under present conditions. Conversion requires technical, commercial and regulatory support.

Commercial Flow Must Be Sustained

The announcement did not establish that a full-field commercial threshold had been reached. Well variability, sustained productivity, water handling, infrastructure requirements and gas-sales arrangements will affect development economics. Regulatory approval and an exploitation licence are also necessary. The proposed gas-to-power pathway adds equipment, commissioning and offtake considerations beyond the current pilot.

The Work Program Adds the Next Context

Results from drilling and recompletions, supported by longer-duration production data for each well, will be the next indicators to assess. Updates on gas-to-power implementation and regulatory discussions may clarify the route towards reserve classification and licensing. Any 2027 appraisal campaign will depend on the technical conclusions drawn from the present work.
