An array of property data which describe the characteristics of equipment or materials in or around the borehole of a well.

well_log_trace_s (PK, M: CHAR VARYING(19))

Surrogate key of the table.


data_trace_id (O: CHAR VARYING(40))

data_trace.identifier
The identifying label assigned to a data trace.


trace_value (O: CHAR VARYING(16))

data_trace.trace_value
A multidimensional array of data containing one or more characteristics which can be indexed in various ways.


wellbore_id (O: CHAR VARYING(40))

wellbore.identifier
Identifier used to identify a wellbore within a well. This is often a sequence number or character, such as 1, 2, A, B, C, etc.
This column has been duplicated through attribute well_log_trace.wellbore, which establishes the relationship between the original and duplicated column(s).
This column is a duplicate of column wellbore.wellbore_id.


brhl_gnr_run_s (FSK, O: CHAR VARYING(19))

well_log_trace.borehole_generation_run
Indicates the activity which determined the values of the well log trace. This entity would be used for measurement while drilling.
Defines a foreign key to table brhl_gnr_run.


created_by_s (FSK, O: CHAR VARYING(19))

well_log_trace.created_by
Indicates the activity responsible for the determination of the trace data.
Defines a foreign key to table log_trace_anal.


digitize_doc_s (FSK, O: CHAR VARYING(19))

well_log_trace.digitize_document
Indicates the activity which is responsible for producing the data in its digital form.
Defines a foreign key to table digitize_doc.


grid_geom_bhv_s (FSK, O: CHAR VARYING(19))
grid_geom_bhv_t (O: CHAR VARYING(16))

grid_element_behavior.grid_geometry_behavior
This is the description of grid geometry for which this set of grid element properties are defined.
grid_geom_bhv_s: Implements a foreign key to a row in one of the tables projected from entity grid_geometry_behavior depending on the value of the next column (See below).
grid_geom_bhv_t: Defines the name of the referenced table. Possible values are defined in @grid_geometry_behavior.


production_log_s (FSK, O: CHAR VARYING(19))

well_log_trace.production_logging
Specifies the activity which recorded the trace data.
Defines a foreign key to table production_log.


r_naming_system_kd (FNK, O: CHAR VARYING(40))

well_log_trace.ref_naming_system
The name space in which the identifier is specified as unique.
Defines a foreign key to table r_naming_system.


wellbore_s (FSK, O: CHAR VARYING(19))

well_log_trace.wellbore
Indicates a wellbore which is evaluated by the well log trace.
Defines a foreign key to table wellbore.


wrln_log_pass_s (FSK, O: CHAR VARYING(19))

well_log_trace.wireline_logging_pass
Indicates the activity which is responsible for measurement of the well log trace values. This entity is used for wireline logging.
Defines a foreign key to table wrln_log_pass.
