  1. Well Log Classification Overview

  2. Well Log Classification and Cataloging PWLS Class Repository Well Log Data Repository Well Log Catalog Industry Data Company Data

  3. Activities Enabled by PWLS Meta Data • Classify well logs • Classify well log channels • Query for well logs • Query for well log channels

  4. 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

  5. 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

  6. 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

  7. 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

  8. 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

  9. 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
