Genericity of classification original acquired data  primarily co. data company channel class well log service class computed data  primarily industry data well log curve class well log tool class processed data  combined approach

Query by technology goal: logs of a given technology industry classification:well log tool class company classification: well log service class catalog: classification by well log service class result: well log data

Query by channel attributes goal: channels of a given object, property, function, ... industry classification:well log curve class company classification: company channel class class catalog: classification by company channel class result: well log data

Query by propery type goal: channels of a given property type industry classification: well log curve class company classification: company channel class class catalog: classification by company channel class result: well log data

Parameter-Augmented Query goal: well logs, subject to parameteric constraints e. g. total_depth > 33000 ft industry classification: param spec (property type) e. g. Bottom_Depth company classification: company parm spec e. g. BOTTOM_DEPTH catalog: parametric classification e. g. BOTTOM_DEPTH=44000(m) result: well log data
