POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
This defines a set of fluid phase properties. These include data for aqueous, oleic and vapor phases. This set of properties is unordered and each property in the set should be defined with a pressure and temperature, with bubble point pressures for oleic phases and dew point pressures for vapor phases.
- fluid_system (M, K: fluid_system(fluid_property_set)) (C128)
- This is the fluid system for which this set of fluid properties is defined. Each fluid_property_set must describe one fluid_system.
- activity (O, K, I: activity(process_data))
- Defines the activity which created this instance. Each fluid_property_set may be the result of one activity. Inherited from process_data.
- description (O, I: ndt_comment) (C117)
- A remark or comment about the instance. Inherited from e_and_p_data.
- instance_create_date (O, I: ndt_date_tod) (C126)
- This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance. Inherited from e_and_p_data.
- instance_creator (O, I: ndt_identifier) (C126)
- This is the person, company or application that created this instance. This identifies the party responsible for loading this instance. Inherited from e_and_p_data.
- last_updated (O, I: ndt_date_tod) (C126)
- This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships). Inherited from e_and_p_data.
- last_updated_by (O, I: ndt_identifier) (C126)
- This records the person or application making the update to this instance. Inherited from e_and_p_data.
- preferred_flag (O: ndt_boolean) (C128)
- The flag is set to True if this instance of fluid property set is the preferred set for the designated fluid system. Only one fluid property set should be preferred for each fluid system.
- source (O, I: ndt_identifier) (C126)
- The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC". Inherited from e_and_p_data.
- data_collection (I, V: SET[0:?] data_collection_content(collection_part)) (C020)
- Indicates the data collections that include this instance of E and P data. Each fluid_property_set may be a member of one or more data_collection_content. Inherited from e_and_p_data.
- document_information_content (I, V: SET[0:?] document_information_content(e_and_p_data)) (C136)
- These are the document specification parts that include this data value and define its meaning within a document specification. Each use may define a different meaning, and many uses are allowed. Each fluid_property_set may be included in one or more document_information_content. Inherited from e_and_p_data.
- fluid_phase_aqueous_pvt (V: SET[0:?] fluid_phase_aqueous_pvt(fluid_property_set)) (C128)
- These are the pressure and temperature dependent properties of the aqueous fluid phase in this fluid property set. Each fluid_property_set may consist of one or more fluid_phase_aqueous_pvt.
- fluid_phase_oleic_pvt (V: SET[0:?] fluid_phase_oleic_pvt(fluid_property_set)) (C128)
- These are the pressure, temperature and bubble point dependent properties of the oleic fluid phase in this fluid property set. Each fluid_property_set may consist of one or more fluid_phase_oleic_pvt.
- fluid_phase_vapor_pvt (V: SET[0:?] fluid_phase_vapor_pvt(fluid_property_set)) (C128)
- These are the pressure, temperature and dew point dependent properties of the vapor fluid phase in this fluid property set. Each fluid_property_set may consist of one or more fluid_phase_vapor_pvt.
- graphical_element (I, V: SET[0:?] graphical_element(depicted_object))
- Specifies one or more graphical elements which are depicting this data item. Each fluid_property_set may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- process_data_item (I, V: SET[0:?] process_data_item(process_data))
- Defines where this data was used by an activity. Each fluid_property_set may be the value for one or more process_data_item. Inherited from process_data.
