CNOOC
CNOOC has companies with stakes, operatorships or plants in Canada, China, Indonesia, Iraq, Nigeria and United Arab Emirates in OESA's data. The figures apply to each country separately and are not the group's global production.
In other countries
The companies that belong to CNOOC outside the Norwegian shelf, according to OESA's data. Each country has its own source and period, so the figures apply to each country separately. They are not the company's global production, and they are not added up.

Estimate: Calculated by OESA, not figures from the company: for each field the share that applied in each period is multiplied by the production from GEM (2025), converted to oil equivalent and summed over 4 fields and licences. Some shares are stated as of 2 Mar 2026 and may have differed earlier in the period. Some shares are rounded by the source to whole percent. Oil equivalent by the Norwegian Offshore Directorate's rule: oil, condensate and NGL in Sm³ count equally, 1,000 Sm³ of gas = 1 Sm³ o.e. and 1 tonne of NGL = 1.9 Sm³ o.e. Estimate: the source gives m³ without reference conditions, and the figure is treated as Sm³. The error can be up to about 5%. Oil equivalent by the Norwegian Offshore Directorate's rule: oil, condensate and NGL in Sm³ count equally, 1,000 Sm³ of gas = 1 Sm³ o.e. and 1 tonne of NGL = 1.9 Sm³ o.e. Converted from barrels: 1 barrel = 0.158987 m³ (42 US gallons). The source's barrels are at 60 °F and Sm³ at 15 °C; the difference is under 0.1%. Not included in the sum: 38 fields or licences where the production does not cover the whole period or applies to another period. The figure applies in China and is not the company's global production. Per day: Sm³ o.e. × 6.29 barrels per Sm³ divided by the number of days in the period. Rounded to the nearest 10 below 1,000, the nearest 100 below 10,000 and the nearest 1,000 above that.

Estimate: Calculated by OESA, not figures from the company: for each field the share that applied in each period is multiplied by the production from GEM (2025), converted to oil equivalent and summed over 1 field or licence. Iraq: EITI describes the agreements with the international oil companies as service contracts with the state oil companies, and in the Kurdistan region as production sharing contracts. A share in Iraq is therefore a share in the contract, not ownership of the field or the oil, and production by share is production by contract share. OESA reads GEM's shares for Iraq the same way. Some shares are stated as of 2 Mar 2026 and may have differed earlier in the period. Some shares are rounded by the source to whole percent. Oil equivalent by the Norwegian Offshore Directorate's rule: oil, condensate and NGL in Sm³ count equally, 1,000 Sm³ of gas = 1 Sm³ o.e. and 1 tonne of NGL = 1.9 Sm³ o.e.

The production by share is not calculated for 2025. The reason: 2 fields or licences where the production does not cover the whole period or applies to another period.

Notes
- The companies in each country are linked to the group by LEI, registration number or curated with a source, never by name similarity. GLEIF consolidation concerns the accounts, not ownership shares, and never moves production.
- The figures apply to each country separately, with that country's period and source. They are not the company's global production, and they are not added up.
