5.1 Overview of the Simple Product Volume Data Object

Figure 5.1-1 shows the main data types and relationships between them that comprise the Simple Product Volume data objects; this set of objects works together to cover these capabilities:

• Describe the reporting entities:

• List of entities,
• Any arrangement of hierarchies,

• Reference the data for the physical entity

• Report volumes per reporting entity:

• Production, injection, dispositions, deferred production and inventories, transfers to other entities, and terminal lifting
• For any time period, any type of produced or service fluid

• Transfer supporting data:

• Well tests, well production parameters

The Reporting Entity object is important because all the volume and event-driven data transfers use it to refer to the “thing” whose properties they are reporting. Figure 5.1-2 shows a UML diagram of the data model (simplified to the top levels); it shows how the other types of data objects reference back to the reporting entity for identity. (NOTE: The UML model is used to produce the PRODML schemas and is provided (as an XMI file) when you download the standard.)
