The new field contains proven geological reserves of 100 million metric tons of oil & gas equivalent, making it one of biggest crude oil production bases in China.
In May 2020, CNOOC said it would invest $4 billion to increase its production capacity in Tianjin.
The Bozhong 13-2-2 well was drilled and completed at a depth of 5,223 m, and encountered oil pay zones with a total thickness of approximately 346 m.
The well was tested to produce an average of approximately 1,980 barrels of crude oil per day.
The company expects daily crude oil & natural gas generation from the well to reach 300 tons and 150,000 cu m at a later date.
Zhou Xinhuai, CNOOC´s General Manager of Exploration Department said:
- The successful exploration of Bozhong 13-2 structure is another exploration achievement for the company to continuously enhancing its efforts in oil & gas exploration in offshore China
- The new field is expected to play a pivotal role in helping the company produce 40 million tons of crude from the Bohai oilfield during the 5-Year Plan period (2021-25)
- The Bohai oilfield is likely to start production in 2023 and achieve a peak output of 1.2 million tons of oil equivalent
CNOOC began looking for oil & gas in the Bohai Sea half a century ago.
Since 2019, it has discovered the 100-billion-cbm gas field Bozhong 19-6 and the 100-million-ton oilfield Kenli 6-1.
