This article demonstrates how ownership analysis works for CNOOC.
For an explanation of ownership concepts including Company Level, Company Is Top Level, and Field Interest Is Direct, see the Understanding ownership in Lens Upstream article.

Company Example
Asset Name: Golden Eagle
Golden Eagle is a producing oil field in the UK North Sea operated by CNOOC Petroleum Europe Limited, a wholly owned subsidiary of CNOOC International.
This example demonstrates how the same asset can be attributed to different companies depending on the selected Company Level.
In this example, the results have been filtered to Golden Eagle, with no company filter applied.
Ultimate Company Level
When the Company Level is set to Ultimate, the asset appears under the highest parent company in the ownership hierarchy.
In this view:
Company Is Top Level = Y for CNOOC.
Field Interest Is Direct = N because CNOOC does not directly hold the field interest.
The Company to Field Chain column shows how ownership is attributed through the corporate hierarchy.
This perspective answers the question:
"Which ultimate parent company can this asset be attributed to?"
Direct Company Level
When the Company Level is switched to Direct, the asset is displayed against the entity that directly holds the field interest.
In this case, the result moves from the parent company to the operating subsidiary within the CNOOC organization.
In this view:
Company Is Top Level = N because the entity sits below CNOOC within the hierarchy.
Field Interest Is Direct = Y because the company directly holds the asset interest.
The Company to Subsidiary Chain and Company to Field Ownership Chain columns reveal the ownership path linking the asset back to the ultimate parent.
