- Sinopec Shengli Jiyang zone cumulative shale oil production exceeded 2 million tonnes, with 59 wells above 100 t/day (peak 263 t/day).
- Annual output is set to reach 700,000 t in 2025 and the zone targets 3 million t/year by the end of the 15th Five‑Year Plan.
- Proven reserves total 327 million tonnes with estimated resources of 1.05 billion tonnes.
- Drilling cycle for 6,000‑meter wells fell from 133 days to 17 days, and average expected cumulative production per well exceeds 43,000 tonnes.
Key achievements
The Shengli Jiyang shale oil demonstration zone has passed cumulative production of over 2 million tonnes; 59 wells have peak daily output >100 t (max 263 t); annual output rose from an initial 131,000 t toward a 700,000 t target for 2025 and completed its demonstration tasks one year early.
Technical progress
The project addressed low‑maturity, deep‑burial, complex‑fracture reservoirs by developing reservoir theories for continental rift shale and six technology series—including three‑dimensional development, optimized fast drilling, and efficient balanced fracturing—cutting the 6,000 m drilling cycle from 133 to 17 days and raising core equipment localization to >95%; average expected cumulative production per well exceeds 43,000 t.
Reserves and discoveries
Reported proven reserves total 327 million tonnes with estimated resources of 1.05 billion tonnes; three shale oil fields (Xinxing, Xinhe, Xinfeng) were discovered within the zone, expanding the resource base for crude replacement in eastern China.
Targets and national context
The zone targets 3 million tonnes per year by the end of the 15th Five‑Year Plan and is positioned alongside other Chinese shale initiatives—Xinjiang Jimusaer, Daqing Gulong and the Qingcheng area in Changqing—to support scaling continental rift basin shale oil development.
