Name	Value Domain	Property / Storage Unit	Description	Required / Default	Type
Azimuth	double	Plane_Angle deg	The azimuth of the borehole when the event took place.	No	NUMBER
Bottom_Hole_Temperature	double	Temperature degC	The temperature at the bottom of the hole when the kick occurred	No	NUMBER
Circulation_Severity_Flag	boolean	NA	A flag to denote whether the lost circulation was minor or severe. A value of 1 signifies severe, a value of 0 signifies minor	No	NUMBER(1)
Drill_Bit_Bottom_MD	double	Depth m	The drill bit bottom measured depth of interval of interest subject to manage the risk the depth at which the event occurred.	No	NUMBER
Drill_Bit_Bottom_TVD	double	Depth m	The drill bits bottom TVD of interval of interest subject to manage the risk the depth at which the event occurred.	No	NUMBER
Drill_Bit_Top_MD	double	Depth m	The drill bit top measured depth of interval of interest subject to manage the risk the depth at which the event occurred.	No	NUMBER
Drill_Bit_Top_TVD	double	Depth m	The drill bits bottom TVD of interval of interest subject to manage the risk the depth at which the event occurred.	No	NUMBER
Equipment_Component	CODE	NA	The component of the piece of equipment that caused the event.	No	VARCHAR2(64)
Event_Id	Event		Reference to the event/risk for which the environment is defined.	Yes	NUMBER(38)
Existence_Kind	REF_EXISTENCE_KIND	NA	A reference value that describes the state of existence in the lifecycle of the entity, for example, Planned, Predicted, Required, Simulated, and Actual.	Yes Actual	VARCHAR2(64)
Failed_Area	CODE	NA	The area of the piece of equipment that caused the event (Internal/External)	No	VARCHAR2(64)
GUID	STRING128	NA	Globally Unique IDentifier for an instance of a class. USAGE NOTES: There are two cases: 1) GUID is not populated or used; and 2) it is populated with a value that is globally unique. If the GUID is populated there are two means of doing so for a given project: 2a) Seabed automatically generates and populates the GUID when an instance is created (valid only on Oracle based systems); and 2b) the GUID is generated and populated by an application (other than Seabed) on instance creation. Whether Seabed automatically generates GUIDs for a project is determined by the Auto_GUID flag in SDS_Account. Note that techniques 2a and 2b can coexist in the same project. When GUIDs are automatically generated an application can override the automatically generated GUID with its own GUID by simply supplying the GUID value. Applications that generate their own GUIDs and populate the GUID column will function correctly on projects which have automatic GUID generation turned on.	No	VARCHAR2(128)
Hole_Bottom_MD	double	Depth m	The bottom measured depth of interval of interest subject to manage the risk or the depth at which the event occurred.	No	NUMBER
Hole_Bottom_TVD	double	Depth m	The bottom TVD of interval of interest subject to manage the risk or the depth at which the event occurred.	No	NUMBER
Hole_Size	double	Cylinder_Diameter mm	The hole size at the time of the event/risk.	No	NUMBER
Hole_Top_MD	double	Depth m	The top measured depth of interval of interest subject to manage the risk or the depth at which the event occurred.	No	NUMBER
Hole_Top_TVD	double	Depth m	The top TVD of interval of interest subject to manage the risk or the depth at which the event occurred.	No	NUMBER
Id	ID	No_Unit	Unique identifier for this entity.	Yes	NUMBER(38)
Inclination	double	Plane_Angle deg	The deviation angle of the borehole when the event took place.	No	NUMBER
