Oil Reserves

Identifies companies and other entities that own or control economically recognized reserves or resources of crude oil, condensate, bitumen, or other liquid hydrocarbons through direct ownership or extractive rights. Reserve class, development status, conventional or unconventional type, geography, and ownership basis must be recorded. Service provision, refining or transport without reserve interests, passive financial exposure, mere exploration without an established economic resource, and fully divested or abandoned assets are excluded.
