This entity describes the connection between two wellbore component facilities. It is not necessary to use this entitiy to describe components connected together to form an assembly, as the parts and assembly list relationship on wellbore component facility can be understood to contain this. Rather this should be used where, for example, two wellbore_component_facilities that are both assemblies are connected together, without one becoming part of the other.

wellbore_component_facility (M, K: wellbore_component_facility(connected_to))

This is the designated wellbore_component_facility that this connection is described for. For example, to describe a packer connected to a casing_string, this attribute points to thte packer. Each wellbore_component_facility_connection must connected to one wellbore_component_facility.


connected_with (M, K: wellbore_component_facility)

This is the other wellbore_component_facility that is connected to the designated wellbore_component_facility. To describe a packer connected to a casing_string, this attribute points to the casing_string. Each wellbore_component_facility_connection must connected from one wellbore_component_facility.


start_time (O, K, I: ndt_date_tod)

Start time of the association. Inherited from transient_association.


description (O, I: ndt_comment)

A description of the transient association. Inherited from transient_association.


duration (O, I: ndt_time)

Defines the duration of the association expressed in any valid units of time. Inherited from transient_association.


end_time (O, I: ndt_date_tod)

End time of the association. Inherited from transient_association.


caused_by (O, I: activity(cause_association))

Specifies the activity which establishes this association. Each wellbore_component_facility_connection may be caused by one activity. Inherited from transient_association.


data_collection (I, V: SET[0:?] data_collection(collection_content))

Indicates the data collections that include this instance of E and P data. Each wellbore_component_facility_connection may be a member of one or more data_collection. Inherited from e_and_p_data.


graphical_element (I, V: SET[0:?] graphical_element(depicted_object))

Specifies one or more graphical elements which are depicting this data item. Each wellbore_component_facility_connection may be depicted by one or more graphical_element. Inherited from e_and_p_data.


kind (O: ref_wellbore_component_facility_con)

The kind or type of wellbore component facility connection. For example, this might be "inside", "outside", "above" or "below". Each wellbore_component_facility_connection may kind one ref_wellbore_component_facility_con.


ref_transient_period (O, I: ref_transient_period) (1222)

The type of period over which the property applies, such as day, month, quarter, cumulative, etc. Inherited from transient_association.


terminated_by (O, I: activity(terminate_association))

Specifies the activity which established the termination of a transient association between two objects. Each wellbore_component_facility_connection may be terminated by one activity. Inherited from transient_association.

Local rules:

Uniqueness Constraint
wellbore_component_facility, connected_with, start_time
[I: transient_association] Instance Value Constraint (1259)
If REF_TRANSIENT_PERIOD is EVENT, then both START_TIME and END_TIME must either be blank or be identical.
[I: transient_association] Instance Value Constraint
If REF_TRANSIENT_PERIOD is either YEAR TO DATE, MONTH TO DATE or CUMULATIVE, then END_TIME must be instantiated.
[I: transient_association] Instance Value Constraint
If REF_TRANSIENT_PERIOD is ANNUAL, SEMIANNUAL, QUARTER, MONTHLY, DAILY, or HOURLY, then either both START_TIME and END_TIME are blank or both must be instantiated.
Supertype path(s):
e_and_p_data > association > transient_association > wellbore_component_facility_connection.
