Name	Squeeze_Cement_Stage
Entity Type	Table
Description	The detailed information about the Squeeze cement stage of a cement job. A squeeze cement job is the process of forcing a cement slurry through holes or splits in the casing or liner. Once the slurry encounters a permeable formation, the cement solids are filtered out of the slurry as the liquid phase is forced into the formation matrix in the form of cement filtrate. A properly designed squeeze-cement operation will fill the relevant holes and voids with cement filter cake that will cure to form an impenetrable barrier

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)

Circulation_Rate	double	Flowrate m3/h	Circulation rate of the fluid during this stage of the cementing operation	No	NUMBER
Circulation_Time	double	Time s	Circulation time between stages	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
End_MD	double	Depth m	Measured depth at the end of the activity or proposed depth end of the activity.	No	NUMBER
End_Pressure	double	Pressure kPa	Pressure Left On After Cementing activity	No	NUMBER
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)
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_Annular_Pressure	double	Pressure kPa	Final Annular Casing Pressure	No	NUMBER
Final_Casing_Pressure	double	Pressure kPa	The pressure in the Casing at the end of the cement stage	No	NUMBER
Final_Squeeze_Pressure	double	Pressure kPa	Final Squeeze Pressure	No	NUMBER
Final_Tubing_Pressure	double	Pressure kPa	The pressure in the Tubing at the end of the cement stage	No	NUMBER
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)
