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.

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 > 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
