Activities Enabled by PWLS Meta Data • Classify well logs • Classify well log channels • Query for well logs • Query for well log channels
Classify a Well Log / Channel / Parameter • well log well_log_service_class • by interpretation of well log header • channel company_channel_class • validate against dictionary • parameter company parameter spec. • validate against dictionary
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
