Run numbering in logs
  • Log wellLog objects have character strings for
    run and pass number
  • Legacy from LIS, DLIS, WellLogML
  • Unable to search or order
  • Propose to add BHA run number (integer) to log
    header
  • Enables link to BHA and bit information

Enabling Automation
  • Publish/Subscribe mechanism
  • Defined in 2000 XML technology has moved on
    since then
  • Difficult to implement need web server at both
    ends
  • Does not work through firewalls
  • POSC will publish statement on Pub/Sub
  • Technical team to investigate alternatives
  • GetFromStore Interface
  • Use dTimLastChanged. Requires lots of queries
  • Implement Change log item
  • Current/active well wellbore
  • Need to implement new server behavior
  • Needs documentation of recommended practices
  • Updating activity codes

9
Organization of Server Data
  • Issues with one well per sidetrack
  • How to find related wells?
  • API Well number different for each wellbore (1st
    10 digits are the same for each well)
  • Need to specify best practice for well/wellbore
    naming
  • Maybe a link to POSC global well name initiative

Technical Team
  • Join the SIG and help drive the standard!
