4. © Copyright 2006 POSC Success Factors Collaboration – steer [just] clear of competitiveness Value – neither theory nor art are sufficient reasons, must enhance real business advantages Change Agency – standardization requires change –Innovation –Resources –Marketing –Planning –Execution

5. © Copyright 2006 POSC Modes of Collaboration Late –Clean-up diversity  ride replacement cycles Early –Make a good start  ride adoption cycles Top-Down –Sold from the top  visible, funded efforts Bottom-Up –Incremental knitting  almost invisible, evolutionary at best

6. © Copyright 2006 POSC May 9-11 Events Public Seminar and Vendor Exhibition (May 11, Thursday) –Current reports from actual experiences and plans from oil companies, service companies, and software companies. SIG Working Meetings – Technical Teams We address implementation feedback and continuing detailed specification issues – Use Case and Requirements Team We address possible future areas of focus: drilling reports, completions, environmental, well services, well stimulation, service rig reporting. – Implementation Support Team People supporting WITSML-enabled environments share lessons learned and current issues and challenges.
