Entity Type	Table
Description	A periodic report at a wellsite that documents over a given period current rig information such as weather conditions, personnel on board and operation performed on the rig. A report may contain data that are observed/estimated at the moment of the report that cannot be derived from another source or/and the result/summary of activities that have been captured on the rig.

[Previous] [Next] [Top]

Name	Value Domain	Property / Storage Unit	Description	Required / Default	Type
Activity_Program_Id	Activity_Program		Reference to the program during which the activity was performed.	No	NUMBER(38)
Activity_State	STRING64	NA	The current state, or status, of the activity. Activity state is a refinement of the lifecycle indicator Existence_Kind. For example, a drilling job whose Existence_Kind is "Actual" could have an activity state of "turning to the right", "suspended due to weather", or "tool makeup or breakdown". An activity whose Existence_Kind is "Required" could have State values like "under investigation", "proposed" and "AFE approved". Note: The valid list of activity states will vary from one kind of activity to another, so the values entered into this column are not validated via a lookup table.	No	VARCHAR2(64)
Activity_Template_Id	Activity_Template		The identifier of the activity template which activates or characterizes the Activity.	No	NUMBER(38)
Avg_Casing_Pressure	double	Pressure kPa	The average pressure in the casing observed during the period of this report	No	NUMBER
Avg_Penetration_Rate	double	Drillbit_Penetration_Rate m/h	Driller estimate of the representative rate of penetration (R.O.P.) for the reporting period	No	NUMBER

Drillstring_Drive_Torque	double	High_Torque kN.m	Driller estimate of the average torque applied to the drill string - measured at the rotary table or top-drive - over the reporting period.	No	NUMBER
Duration	double	Time s	The duration of the activity. For planned activities, this would be expected duration.	No	NUMBER
End_Date	DATE	NA	The date and time at which the activity will end or did end. For planned activities, this would be expected end date.	No	DATE

External_Reference	STRING64	NA	A value that is used by an external organization to reference this activity. For example, if an external organization is hired to perform this activity, this column could be used to store the work order or purchase order number that organization uses to reference this activity.	No	VARCHAR2(64)
Final_Report_Flag	boolean	NA	Flag indicating whether the report is the final one or not.	No	NUMBER(1)
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)
