History
PWLS SIG
– Evolved from PWLS project Phase 2
– PWLS Project published Version 1 standards in ’01
• 6 major types of acquisition well logging tools addressed
• 3 major service companies involved
• Classification
– Good: based on broad taxonomy of property (measurement) types
– Issue: taxonomy was proprietary
– Issue: alternate classification was also adopted
•
History
PWLS SIG

• More players; more oil company players
• Clear need to resolve classification issues
• Focus shifted to oil company calculated
– PWLS Version 2 released in ’03
• POSC now has rights to the property (measurement) type
taxonomy
