Columns

[Previous] [Next] [Top]
NameValue DomainProperty /
Storage Unit		DescriptionRequired /
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)
Borehole_Id Borehole
The identifier of the borehole in which the activity occurred. Yes
 NUMBER(38)
Borehole_Pty_Id Logging_Hole_Condition
The borehole condition associated with this run. No
 NUMBER(38)
Category CODE NA
 Category of the logging activity Yes
 VARCHAR2(64)
Conveyance_Type CODE NA
 The method utilized to move the logging tool through the borehole for instance, Wireline. No
 VARCHAR2(64)
Drill_Fluid_Id Drill_Fluid
The drill fluid encountered during the logging activity. No
 NUMBER(38)
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
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)
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)
Id ID No_Unit
 Unique identifier for this entity. Yes

Insert_Date DATE NA
 Date the entity was created in the repository No
 DATE

Internal_Reference STRING64 NA
 A value that is used internally within the organization to reference this activity. No
 VARCHAR2(64)
Log_Total_Depth double Depth
m		 Total depth reached during the logging activity as reported by logging engineer. No
 NUMBER
Logging_Activity_Type R_Logging_Activity
The code for the activity type in a logging activity. No

Logging_Category R_Logging_Category
The code for the activity categories in a logging activity. No
 VARCHAR2(64)
Logging_Mode R_Logging_Mode
The code for the activity modes in a logging activity. No
 VARCHAR2(64)
Name ENTITY_NAME NA
 The name given to any object or data item, e.g. name of Well, name of Field, etc. No
