Sinopec’s first deep coal‑seam gas well surpasses 50 million m³ cumulative production
- Sinopec Huabei's Da Niudi Yangmei 1HF deep‑coal‑seam gas well has exceeded 50 million m³ cumulative production and yields ~27,000 m³/day.
- Well was deployed in 2022 and entered production in 2023 after fracturing delivered high initial flow.
- Operations use data‑driven optimization plus wellhead liquid separation, coal‑fines and sand removal, and intelligent injection to stabilize output.
Overview
As of May 8, the Da Niudi Yangmei 1HF deep coal‑seam gas well achieved cumulative production exceeding 50 million cubic meters and currently produces about 27,000 m³/day, demonstrating sustained, controllable wellhead pressure.
Timeline and performance
The well was deployed in 2022, underwent fracturing to attain high initial flow, and entered commercial production in 2023; since then operators have focused on maintaining rapid early output, stable mid‑term succession and managed long‑term decline.
Operational measures
Field practice emphasizes detailed on‑site data collection and production research, stage‑specific optimization standards, dynamic regime adjustments, and technologies including wellhead liquid separation, coal‑fines removal, sand removal and intelligent injection to stabilize production and control solids and fluids.
