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.
Its located 140 km off the coast of Tianjin at an average water depth of 23.2 m.
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.
