How slow should I lower to bottom?

Did I hoist high enough?

Can I start my pumps?

What RPM?

Is my crew safe?

What was survey depth?

Did I forget something?

NOVOS system overview

Surface Data from Rig Instruments

NOVOS takes aggregated data from surface instrumentation, rig

equipment and 3rd party data sources

NOVOS Integration Kit

Application Server, Interface SBC, Mission Control IPC,

Visualization IPC

NOVOS User Interface and Drillers set up

NOVOS screen replaces one of the driller’s Amphion

Downhole Data

NOVOS takes data from NOV and 3rd party downhole tools,

either by mud pulse or IntelliServ high speed network

Drilling Practices

Transitioning from sliding to rotating zone

During transition upwards of 30 G’s seen by the EMS

RPM variance seen from 0 to +500 RPM while moving pipe off bottom due to static friction

RPM variance seen coming from the high bend angle when rotating

Burst Analysis HF Data

EMS showing high torsional vibrations, magnitudes seen in burst data below

• Burst data shows Gyro RPM fluctuations from 0-140 RPM’s during this period • Burst dominant frequency 0.28 hz which is the first torsional natural harmonic of

the string • There is also a secondary frequency generated by the high bend angle of the

motor creating a second peak in the Gyro RPM signal

IntelliServ system overview

WIRED DRILL PIPE

DataSwivel

NetCon

Surface network controller and management system

Wired Drillstring

Enables high speed data transmission across drillstring

DataLinks or ASMs

Installed periodically along drillstring to condition and

amplify data signal (Matted to normal R2 or R3 joints of pipe)

MWD Interface Subs Interface between MWD, LWD tools and RSS tools and IntelliServ network

Reliability and Performance

¹Uptime is defined as the percentage of time that the Network is online and transmitting high-speed data. Uptime

% = (Possible Data Hours - Downtime)/ Possible Data Hours

CLOSED LOOP

• NOV topdrive software upgrade mitigates torsional vibration and stick • Sends an inverse wave into the drillstring, much like noise cancelling

• Improves drilling performance by • Improving borehole quality

• Improving RSS directional control

• Reducing torsional and coupled lateral vibrations

• Engaging cutters consistently

• Increasing founder point for higher ROP

• Increasing MTBF

• Improving MWD decoding

SoftSpeed2

“Turn the Lights on” - WDP

• Coaxial cable enables 57.600 bps

Lateral Vibration

• Sensors along the entire drillstring

• monitor and control downhole

conditions throughout the well

Well Control Awareness Lost circulation events

• Along-string measurements for improved well control awareness

‒ Internal & annular pressure, temperature, rotation and vibrations

The RT annular pressure readings were used to calculate the relative height of the fluid column, providing a clear understanding of the wellbore condition
