Overview
- CNOOC says the Qinhuangdao 29-6 discovery in central Bohai Sea holds proved in-place volumes exceeding 100 million tons of oil equivalent.
- The discovery well reached 1,688 meters, encountered 66.7 meters of oil pay, and tested at about 2,560 barrels of crude per day.
- The main reservoir is the shallow-buried Neogene Minghuazhen Formation producing medium‑heavy crude.
- The company calls it the second one‑hundred‑million‑ton‑class lithological oilfield identified in the mature Shijiutuo Uplift and highlights uplifted peripheral slopes as viable traps.
- The announced find is not in production and will undergo further evaluation, and industry reports note it follows CNOOC’s recent shallow‑water project start‑up in the Pearl River Mouth Basin.
