Mean while in the oil business...
Rep. Bruce Braley, D-Iowa to
Transocean CEO, Steve Newman:
"So you have no mirrored data device so that information is
recorded at some location other
than rig itself?"
Newman: "We do not have
real-time off-rig monitoring of
what's going on the vessel."
Lessons from Macondo

Trends in Formation Testing
• Ever more challenging conditions
• Increasingly more complex tools
• Much more than data acquisition
• Design, execution, and evaluation
• Real time monitoring and control a MUST!

• Adequate pressures and samples?
• Best place for sampling?
• Flowing pressure > saturation/solids onset?
• Mud contamination?
• Capture sample?
• Downhole fluid analysis?

Learnings and Recommendations
• Plan the execution - execute the plan
• Experience matters
Real time monitoring is key in all the above!
• Never walk away with insufficient data
• Integrate…integrate…integrate
• Identify main objectives and challenges
