WellGroup supports hierarchical organization through the parentGroupId field. When set, a group becomes a child of the referenced WellGroup. This lets compliance teams create multi-level groupings — for instance, nesting zone-specific groups under a top-level monitoring network group. Child groups inherit the site scope of their parent, and nested structures appear as collapsible trees in reports and the site map view.
