Who are we ?
• Worldwide leader in the design, manufacture and sale of equipment and
components used in oil and gas drilling
• The provision of oil field inspection and other services and supply chain
integration services to the upstream oil and gas industry
Established: 1841
NYSE: NOV
Employees: 60,000
Revenue (2012): $20b
Not just the Oil Field…
• We solve really big problems

Message from the machine….
So what does that mean ?
• Condition Monitoring
• Condition Based Maintenance
• Predictive Maintenance
• No way.. Not in the drilling industry
The challenges we face
• Extremely Remote Locations
• Extremely Rugged (Rough Neck Proof)
• Low Connectivity
• Extremely Expensive when things break
• Antonov AN 124 rented to fly equipment
• Technology Averse (unless it turns to the right !)
• Tried and Failed a few times… No Trust it will work…
Why can’t we (Drilling Industry) do it ?
Automotive
100 + prototypes, 30 cars at each pre-production
Airlines
747 Example – Redundancy of Systems. Collaboration of partners
Production
Been doing it since the 80s, no moving assets, but similar asset classes
Aerospace (NASA)
Only one chance, it has to work – Testing simulation and software
This is the model NOV plans to replicate
– Data Analysis, Correlation Analysis
Why we should be doing it ?
• Current Day Rate : > $500,000
• Typical Downtime on a fleet : 4%
• Annual Downtime for a 10 Rig Fleet: $72,000,000
• If Downtime is reduced to 3.75% from 4%: Savings of $4,500,000 / yr.
• That goes to the bottom line…
• Or increase Revenue by $18,000,000 @ 25% OP.
• Now imagine Spread Costs which is over twice those numbers
It’s not just the financial impact!
• Incidents in North Sea, Alaska, Gulf of Mexico
• We are all responsible
Maintenance Savings
• Condition Based not Calendar Based
• Extend Maintenance Schedules
– Standard - 4 oil changes by 12000 miles
– New – 1 Oil change at 10500 miles
– Translate that to a fleet of 100 rigs x 3 engines or more

Advanced Rig Monitoring – Virtual Employee
eHawk introduces Machine Learning to learn
from historical data an equipment’s “Normal”
vs. “Abnormal” operations for multiple states.
Dynamically create profiles to
monitor the equipment and listen
for abnormal signatures.
Continuously adapts over time.

What do we measure on a
Top Drive then
• Upstream
Bearing Status
Debris Status
Mud Ingress

Top Drive RPM
– Engines, Generators, Drives
Torque
• Downstream

– Rock formations, DH vibrations, etc.

Machine Learning

Example 1 - Top Drive
• Created Supervised Learning Profiles to monitor for failure signature
detected ongoing.
• Confirmed failure information with Rig
• Root Cause: UV1 valve cycling lubrication fluid in 6 second intervals
Found 14 day Predictor for June 10th
Top Drive Failure (Over Temp) due to
Lube Motor Failure
Example 2 – Engine Temps
Example 3:– Mud Pump
o Drive fault prediction found
o Customer notified
o Rig down 18 hours later
Anomaly Detection triggered on
June 9th for Mud Pump Drive fault
So... No sensors whatsoever ???

• Predictability is key
• When you call the rig with a problem…
Monitoring the BOP
Do we have to do this?
• Current Demographic –
•Older, aging driller demographic
•Influx of younger inexperienced workforce
• New Deepwater Rigs being built – How will we staff them
• Compare Pilots and Drilling Crews ($650 Million Rig)
• Not enough time to train – Serve the iPad Generation
Remote Monitoring – Too many rigs and too few PhDs
Hawaii
Norway
Singapore
Houston
Conclusion
• Are we there yet ?
• There is no end point.
– We can only get better
• Technologies and Capabilities exist
– Let’s use the tons of data
• We have no more excuses
