Today (10th), Yuanba—the world’s first ultra‑deep, high‑sulfur bioreef gas
field—exceeded 40 billion cubic meters of cumulative natural gas production. Gas
is delivered via the Sichuan–East pipeline to six provinces and two
municipalities along the Yangtze, serving nearly 200 million residents and
adding clean‑gas supply to support national energy security and the Yangtze
Economic Belt.
