How can data drive true, automated action?
 How is data collected?
 Where is it stored and processed?
 Is there real signal or just noise?
 How can we build a predictive model?
 When is the right time to take action?

 Oil & gas exploration and production activities generate large

 What opportunities exist for data-driven approaches to improve

Drilling operations
• Predicting drill rate-of-penetration (ROP)
• Motivation: Shorter time to oil production
lowers costs and increases production
• Goals
– Identify optimal parameters for rapid
drilling
– Create an initial approach for drilling
– Potential reduction in damage to
equipment

– Potential reduction in damage to

Predictive maintenance
• Predict equipment function and failure
• Motivation: Failure costs estimated at
$150,000/incident (billions annually)*
• Goals
– Early warning system
– Insights into prominent features impacting
operation and failure
– Reduction of non-productive drill time
– Reduced incidents
