ONGC
ONGC has companies with stakes, operatorships or plants in India and Vietnam 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 ONGC 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 1 field or licence. 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%. Not included in the sum: 6 fields or licences where the production does not cover the whole period or applies to another period. The figure applies in India 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.

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.
