Preferred Solution = Real-time Surveillance
•Acquire quality data
•Transport data to observers
•Convert data to information
•Communicate information to decision-makers

Lessons Learned
• WITSML updates slower than WITS
– Internet time versus direct cable time
• Concurrent use of proprietary system (Riglink, Interact) aids in
monitoring data dead zones
• System is still imperfect, and requires companies to collaborate on
problems
• WITSML must be planned before a project.
– Connections attempted as after thoughts have failed.
