TMK Energy Limited (ASX:TMK) has reported record gas production at its 100%-owned Gurvantes XXXV Pilot Well Project in Mongolia for September 2026, alongside progress on its 2026 Work Program.
Record Production at the Pilot Well Project
September production averaged about 30,800 standard cubic feet per day (872 cubic metres per day), an 8% increase from August's 810 cubic metres per day. The final week of September averaged 33,400 scfd.
Production has grown by more than 300% since a revised reservoir management plan was introduced in August 2025. CEO Dougal Ferguson noted that gas rates continue to rise, with no pump blockages over the past 14 months.
Reservoir Performance and Work Program
Increased gas rates from multiple wells, not only LF-07, indicate desorption is occurring both near wellbores and deeper in the reservoir. Water production remained stable at about 425 barrels per day.
Long lead items have begun arriving, with deliveries expected to finish by mid-October. A workover rig is being mobilised, starting with idle well LF-03, while the drilling rig for production well LF-08 is expected to mobilise within weeks after minor repairs.
Government Support and Gas to Power Project
Management visits to Mongolia confirmed political support for coal seam gas development as a pathway to greater energy independence. Meetings were held with the regulator MRPAM, the Ministry of Heavy Industry and potential offtake partners.
TMK and partner Dashvaanjil Group LLC remain on track to finalise commercial arrangements and reach a final investment decision on the Gas to Power project by the end of October 2026.
Key Takeaways
