7. Pilot Prerequisites Data elements supported by WITSML objects?
Objects supported by vendors?
Level of support by vendors?
WITSML version
File transfer only or API support
Clear objectives - expected outcomes
Connectivity & Infrastructure requirements?
Funding?

8. Next Steps Mudlog object extension incorporated Release Candidate 1.3
Pilot Release 1.3
Evaluate use of mudlog object for other purposes such as Geological Report.

9. Mudlog Object Demonstration
S D C Geologix
Mudlog Object Demonstration
Using GEO & Sitecom

10. Use of Mudlog object in GEO
Finish!
Map lithology names
Select curves to load
Connect to Server
Select Well/Wellbore/Data to load
Start Wizard
The mudlog is created by loading log and mudlog objects directly from a remote WITSML server.
