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

identifier (O, K, I: ndt_name)

The identifying label assigned to a data trace. Inherited from data_trace.


wellbore (O, K: wellbore(well_log_trace))

Indicates a wellbore which is evaluated by the well log trace. Each well_log_trace may characterize one wellbore.


wireline_logging_pass (O, K: wireline_logging_pass(well_log_trace))

Indicates the activity which is responsible for measurement of the well log trace values. This entity is used for wireline logging. Each well_log_trace may be created by one wireline_logging_pass.


borehole_generation_run (O, K: borehole_generation_run(well_log_trace))

Indicates the activity which determined the values of the well log trace. This entity would be used for measurement while drilling. Each well_log_trace may be created by one borehole_generation_run.


production_logging (O, K: production_logging(well_log_trace))

Specifies the activity which recorded the trace data. Each well_log_trace may be created by one production_logging.


ref_naming_system (O, K: ref_naming_system)

The name space in which the identifier is specified as unique.


created_by (O, K: log_trace_analysis(new_trace))

Indicates the activity responsible for the determination of the trace data. Each well_log_trace may be created by one log_trace_analysis.


trace_value (O, I: ndt_trace_value)

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


data_collection (I, V: SET[0:?] data_collection(collection_content))

Indicates the data collections that include this instance of E and P data. Each well_log_trace may be a member of one or more data_collection. Inherited from e_and_p_data.


datum_for_ranking (I, V: SET[0:?] object_ranking(base_object))

Indicates that an object is being used as a basis for comparison with another object. Each well_log_trace may datum for ranking one or more object_ranking. Inherited from object_of_interest.


digitize_document (O: digitize_document(well_log_trace))

Indicates the activity which is responsible for producing the data in its digital form. Each well_log_trace may be created by one digitize_document.


graphical_element (I, V: SET[0:?] graphical_element(depicted_object))

Specifies one or more graphical elements which are depicting this data item. Each well_log_trace may be depicted by one or more graphical_element. Inherited from e_and_p_data.


grid_geometry_behavior (O, I: grid_geometry_behavior(grid_element_behavior))

This is the description of grid geometry for which this set of grid element properties are defined. Each well_log_trace may use the geometry of one grid_geometry_behavior. Inherited from grid_element_behavior.


log_trace_alias (V: SET[0:?] log_trace_alias(well_log_trace))

Indicates various identifiers of this well log trace. Each well_log_trace may be known by one or more log_trace_alias.


log_trace_analysis (V: SET[0:?] log_trace_analysis(well_log_trace))

Indicates an activity which utilized this well log trace. Each well_log_trace may be used by one or more log_trace_analysis.


object_of_ranking (I, V: SET[0:?] object_ranking(ranked_object))

Indicates that an object is being classified in a rank order based on its characteristics. Each well_log_trace may object of ranking one or more object_ranking. Inherited from object_of_interest.


position_in_wellbore (O: SET[0:?] position_in_wellbore(well_log_trace))

Specifies the spatial coordinates associated with this well log trace. Each well_log_trace may be located by one or more position_in_wellbore.


well_log (V: SET[0:?] well_log(well_log_trace))

Indicates well logs which display this well log trace. Each well_log_trace may be depicted in one or more well_log.


well_log_trace_classification (I, V: SET[0:?] well_log_trace_classification(data_trace)) (0705)

This trace is classified by the following classification. Each well_log_trace may be classified by one or more well_log_trace_classification. Inherited from data_trace.
