CNOOC Limited announced on Monday that it has made a new oil and gas discovery at the Bozhong 13-2 field in Bohai Bay. China’s largest offshore operator said the exploration well produced an average of about 1,980 B/D and 5.25 Mmscf/D during initial testing.

The BZ13-2-2 well was drilled in area with an average water depth of about 23.2 m and to a total depth of 5,223 m. CNOOC said the well intersected oil pay zones with a combined thickness of 346 m.

“The successful exploration of Bozhong 13-2 structure is another remarkable exploration achievement for the company to continuously enhancing its efforts in oil and gas exploration and production in offshore China,” Zhou Xinhuai, the general manger of CNOOC’s exploration department, in a statement.

Zhou added that the latest discovery comes after CNNOC began production at the Bozhong 19-6 gas condensate field last October and demonstrations the “promising” exploration opportunities of Bohai.

CNOOC plans to produce up to 555 million BOE in 2021, about 68% of which will come from its domestic operations. Throughout the year, the operator plans to drill a total of 217 exploration wells, bring on stream 19 new developments, and collect nearly 17,000 km2 of 3D seismic.
