ZIYANG, China, May 13, 2026 /PRNewswire/ — [China Petroleum & Chemical Corporation](http://www.sinopec.com/listco/en/)("
Sinopec", HKG: 0386) has announced a major shale gas exploration breakthrough of
its "Project Deep Earth – Sichuan and Chongqing Natural Gas Base". The Ziyang Dongfeng
shale gas field, operated by Sinopec, has secured official approval for proven geological
reserves of 235.687 billion cubic meters from the Ministry of Natural Resources 
of China. This marks the birth of China’s first ultra-deep, 100-billion-cubic-meter-
level shale gas field, pushing exploration and development beyond 4,500 meters.

Sinopec’s Ziyang Dongfeng Shale Gas Field Reports Proven Reserve of 235.687 Billion
Cubic Meters.

The Ziyang Dongfeng in the Sichuan Basin is a large, integrated shale gas field 
discovered in the Cambrian Qiongzhusi Formation, the earth’s oldest commercial shale
layer, formed 540 million years ago. Buried 4,500–5,200 meters deep, it posed globally
recognized exploration challenges such as unclear reservoir characteristics, complex
accumulation mechanisms, thick difficult-to-drill formations, and extreme heat and
pressure.

The Sinopec team moved beyond conventional exploration models. By integrating AI
into geophysical imaging, they effectively "CT‑scanned" subsurface formations, enabling
clear reservoir identification and gas detection. Combined with breakthroughs in
ultra‑deep drilling and fracturing, these efforts have yielded a fully proprietary
technology system for Cambrian ultra‑deep shale gas exploration.

"After over a decade of persistent effort, we have taken Cambrian shale gas from
zero to a hundred-billion-cubic-meter-scale reserve base. This validates the formation’s
vast potential and gives us a replicable technical pathway to expand China’s shale
gas development frontier," said Liu Wei, director of Sinopec Southwest Petroleum
Bureau and representative of Sinopec Southwest Oil & Gas Company. "Our next step
is to drive high-quality exploration and production, accelerate capacity growth 
at Ziyang Dongfeng, and contribute to secure national energy security."

Sinopec continues to drive the high-quality development of China’s shale gas industry.
In 2012, Sinopec discovered the Fuling shale gas field, launching China’s commercial
shale gas development and making China the third country (after the U.S. and Canada)
to achieve commercial-scale shale gas production. By 2017, Sinopec had built Fuling
into China’s first 10-billion-cubic-meter-capacity shale gas field.

Pushing into deeper formations, Sinopec proved the Weirong shale gas field (2018),
the Qijiang shale gas field (2022), and, in 2025, the Yongchuan and Hongxing fields,
each with reserves exceeding 100 billion cubic meters.
