POSC Specifications Version 2.2 Epicentre Logical Data Model

1129 kick and kick_recovery missing

A kick activity can not currently be described in Epicentre. It is needed as an instantaneous activity. A new subtype of activity kick is needed. The volume influx from the formation that generates the kick needs to be linked to the kick activity. This requires an extension for a kick_recovery, subtype of a well_test_recovery. In kick_recovery: kick (M,K: kick) specifies the activity which resulted in this fluid quantity being produced. In kick: kick_recovery (O,V: set[0,?] kick_recovery) indicates the various fluid quantities produced during the kick.

Add entities and relationships

A new wellbore_activity subtype of drilling_kick was added. Add entity drilling_kick_fluid to record the volume of the fluid entering the wellbore. The new entity drilling_kick_fluid needs properties to describe the quantity of fluid in the kick. Add a new diagram to show the new behavior.

Added objects:
WO3:_Drilling_Kicks (Diagram)
drilling_kick (Entity)
drilling_kick_fluid (Entity)
drillstring.drilling_kick_fluid (Attribute)
pty_length.drilling_kick_fluid (Attribute)

pty_bulk_volume_total.drilling_kick_fluid (Attribute)
pty_flow_rate_mass_basis.drilling_kick_fluid (Attribute)
pty_flow_rate_volume_basis.drilling_kick_fluid (Attribute)

Modify diagram and SI rules

Modify the uniqueness rule on the modified properties. Modify diagram to add new subtype of wellbore_activity.

Modified objects:
WO1:_Well_Operations (Diagram)
pty_length.si (Unique rule)
pty_mass.si (Unique rule)
