TMK Energy sees rising gas flow at its Mongolian project, with production up 18% in November, driven by successful reservoir management.

TMK Energy reports continued progress at its Gurvantes coal seam gas project in Mongolia, with gas flow rising 18% in November and 9% in December, the fourth straight monthly increase since a revised reservoir management plan began in August. Pilot wells now produce 466 cubic meters of gas daily, up from 395 in October, with stable water output and declining bottom-hole pressure indicating successful depressurization toward commercial methane flow. A slower production strategy has eliminated pump issues, and a planned shut-in confirmed ongoing pressure reduction. Exploration confirmed coal seams beyond the main site, with one well intersecting thick, gas-rich coal, and core samples collected. The project, covering 8,400 square kilometers near Mongolia’s border with China, holds a 1.2 trillion cubic feet contingent resource and up to 5.3 trillion cubic feet of prospective resource. TMK plans a 2026 drilling program guided by reservoir modeling to accelerate development.
