SubsurfaceResourceInteractionFunction
⊑ DesignedFunction
Realized in
SubsurfaceResourceInteractionProcess
⊑ PlannedProcess
The identity-giving function encompasses the full scope of well operations: obtaining/producing resources from the earth, or storing/injecting materials into the earth. This is what distinguishes a well from other equipment - its designed purpose to interact with subsurface formations and resources.
2 Genus DeterminationDeterminação do Gênero
EngineeredSystembfo:ObjectAggregate (BFO_0000027)
A well is fundamentally a collection of interacting components (wellbore, casing, completion equipment, surface facilities) that work together but lack a single causal boundary. The CFIHOS definition explicitly states 'collection of holes' and 'services related to production', indicating an aggregate system rather than a single unified object. Wells span from surface to subsurface with multiple distinct subsystems.
3 Differentia SpecificaDiferença Específica
∃bearerOf.SubsurfaceResourceInteractionFunctionAn engineered system that interacts with subsurface resources through a drilled wellbore penetrating the earth.
The specific function of subsurface resource interaction combined with the physical requirement of a wellbore are the minimal conditions that distinguish wells from other engineered systems. The wellbore is the essential physical component that enables the subsurface interaction function.
4 Necessary PartsPartes Necessárias
No necessary parts recorded.
The wellbore is the only universal component - all other parts (casing, completion equipment, surface facilities) vary significantly by well type, purpose, and completion design. Used hasComponentPartAtSomeTime because wells may be temporarily without surface equipment during drilling or workover operations.

TransformationTransformação
subsurface material extraction or injection - transfer between surface and underground formations
Wells can operate in production mode (outputs), injection mode (inputs), or service mode (bidirectional). The signature is highly flexible as wells serve diverse purposes from exploration to disposal.

Pipeline StorageTank
C2: Pipeline. C4: StorageTank. Wells interact with subsurface formations through vertical penetration, which is incompatible with horizontal fluid transport (pipelines), surface material transformation (processing plants), or contained surface storage (tanks).
