5.2.1 Reporting Entity Defined

A reporting entity refers to a physical, organizational or geographic “thing” that production data is reported against. For example: wells, fields, leases, business units, countries or states are reporting entities.

At its basic level, the reporting entity data object is simply a “placeholder” object, which all other Simple Product Volume data objects reference. That is, the object identifies the name or ID of the entity against which production data is being reported, but not much other information about it.

Optionally, you can provide other additional data for a reporting entity, using one or both of these methods:

• Define hierarchies to give appropriate context. For example, a hierarchy might be: business unit, fields within a BU, wells within a field, and wellbores within a well (see 5.2.2 Reporting Entities can be Organized into Hierarchies ).

• Reference a physical data object. For example, a reporting entity that is a well or wellbore can reference a fully defined well or wellbore in WITSML (see 5.2.3 Reporting Entities Can Reference “Full” Data Objects ).

Additional information:

• Reporting entities may be of different kinds, which are enumerated in the model (for list of enumerations, see 7.2 Reporting Entity Kinds ):

• Physical asset, e.g. well
• Geographical, e.g. State
• Organizational, e.g. Company

• The behavior of reporting entities according to Kind is not enforced; for example, the schema has no mechanism to restrict well tests being associated only to reporting entities whose kind is “well”.

• Aliases can be used within a reporting entity to enable alternative identifiers to be used (e.g., a well’s name in multiple systems, if they differ).
