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
