The IntelliServ Network

• Grant Pridecos Premium Drill Pipe and
• High-Speed, Bi-Directional Network
• Allows transmission from bottom of string
• Boost and measurements along string

• Temp Rating 302 F
• Pressure Rating 25,000 psi
• Speed 57,000 bps

• NOTE Most BHA components can be converted to
  Intelligent drill string including
• Jars, stabilizers, reamers, drill collars, some
  float valves etc.

Drill String Telemetry Key Applications

• Operational Efficiency
• Reduce non-productive and hidden lost time
• Full telemetry redundancy
• Risk Reduction
• Memory images in RT Enhanced WBS management
• Memory drilling dynamics in RT Reduce BHA
  damage
• Automate pressure control
• Near Future Visibility of Along String
  conditions
• Reserve Expansion
• Improved well placement
• Expand potential for MPD/UBD drilling

Operational Efficiency ? Tool Quality Control
Limited directional response from BHA Initial
build was 1 deg/30m versus expectation of 3
deg/30m Scenario typically forces trip to inspect
downhole equipment Additional tool performance
data available via IntelliServ Enabled SLB to
confidently drill ahead At formation change
directional performance improved
Enables StatoilHydro to Avoid Trip Saves /-2
days Rig Time Saves /-1 Million

Risk Reduction ? Reduce BHA/Tool Damage

Risk Reduction ? RT WBS Management
Ream down _at_ 320 ft/hr
11
Risk Reduction ? Automate Pressure Control

• Project Challenges
• Low shoe strength
• Estimated 200psi above pore pressure
• Potentially would fail if well shut-in
• Narrow Pore Pressure/Fracture Window
• Prevents raising MW
• Shallow hazard depth
• Kick requires immediate detection control
• Potential Risks
• Large volume of gas at shoe and in riser
• Shut-in pressure breaks down shoe
• Gas seepage to seafloor
• HSE risk to people and rig
• Customer Decision
• Well cannot be safely drilled with standard
  technology.
• Project demands fully automated bottom hole
  pressure control system.

Risk Reduction ? Automate Pressure Control
13
Risk Reduction ? Automate Pressure Control
Fully automated system delivers lt10 second
response time Holds BHP within 30psi window while
drilling Holds BHP within 100psi window during
connections Automatically circulates kick out of
well while holding target BHP Enables successful
drilling of well
14
Risk Reduction ? ASM Pressure (Near Future)

• Enhanced risk management via ASM pressure temp
  data
• ECD profile improves visibility of hole cleaning
  issues
• Monitor pressure close to shoe or known weak
  formations
• Full visibility of pressure/temp profile during
  well control events

15
Reserve Expansion ? UBD Geosteering
Highly depleted target reservoir requires high
volume N2 injection while drilling Typical
solution slant drill reservoir with no data
telemetry Enabled solution Geosteer horizontal
through reservoir using rotary steerable
