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 surfacetorque capability issues

– Reduces casing wear

Components:

–

Integrated power section – New-generation bearings and

transmission

– Control unit

– Steering section

Why vorteX ?

Non optimal drilling is caused by

Rotating PDMs with large benthousing settings

Anchored rotary steerablesystems needing high well boreinteraction

Annular bottle necks preventingoptimal flow

Badly matched bit/drivemechanism combinations

Motor BHA

PowerDrive vorteX –

Optimized Drilling Every Time

Optimal Drilling is the result of

Fit for purpose drilling assembliesdesigned for performance

“All rotating” rotary steerable systemsneeding minimal well bore interaction

The correct application of down-holeand surface power

Well matched bit/drive mechanismcombinations

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)


12/20

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


13/20

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 ExampleLocation: 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
