PowerDrive vorteX* Powered Rotary System
Supercharged drilling:
– Customized drilling assembly designed for performance
– Minimal wellbore interaction
– Power to the bit
– Optimizes penetration rates on rigs with surface
torque capability issues
– Reduces casing wear
Components:
– Integrated power section
– New-generation bearings and
transmission
– Control unit
– Steering section
Applications
Hard rock, problem formations
Challenging downhole environment
– High shock / vibration / stick slip / differential sticking
Rig / Top Drive limitations
Tubulars
– Casing wear
– Drill pipe fatigue
Why vorteX ?
Non optimal drilling is caused by
Rotating PDMs with large bent housing settings
Anchored rotary steerable systems needing high well bore interaction
Annular bottle necks preventing optimal flow
Badly matched bit/drive mechanism combinations
Motor BHA
PowerDrive BHA
PowerDrive vorteX –
Optimized Drilling Every Time
Optimal Drilling is the result of
Fit for purpose drilling assemblies designed for performance
“All rotating” rotary steerable systems needing minimal well bore interaction
The correct application of down-hole and surface power
Well matched bit/drive mechanism combinations
PowerDrive vorteX – Configuration
Optimal Drilling is the result of
PowerDrive vorteX Powered by PowerDrive X6
- Push-the-Bit
PowerDrive vorteX Powered by PowerDrive Xceed
- Point-the-bit
Power Section
Specifically designed integrated 7/8 rotor stator power section
High torque output of 18k ft/lbs at 1200gpm
Optimized high temperature elastomer as standard (HN234)
Filter, Bearings, Transmission
Specifically designed bearings and transmission for
increase load and high torque output of power section
Increased weight on bit capability to maximise drilling
performance
Integrated down-hole filter below power section
to increase steering section reliability
Control Unit and Steering Section
All rotating steering section to maximize penetration rate – no
downhole anchor
Cruise control functionality
System temperature rating at 150°C
Full reaming/back-reaming capability
Proven high reliability RSS design
Versatile stabilizer placement

Case Study Example Location: West Africa
Problem
– Drill 12 ¼” Section in one run
– Reduce Shocks and Vibration
events on Downhole tools
– Improve average ROP.
Solution is PowerDrive vorteX*
system
– Decoupled Bit induced S&V
and provide high Bit RPM to
overcome Stick slips. 0.0
