Everything Rotates

“Everything rotates” is the key differentiator for all Schlumberger Rotary Steerable Systems

Key advantages of the PowerDrive family design principles are:-

- can ream, back-ream and drill out shoe tracks

- has no annular restrictions

- minimises risk of differential sticking and lost in hole

- has no stationary anchor limiting ROP

Why PowerDrive Archer?

???

PowerDrive Archer Applications

Kick off from vertical and/or drill high DLS curves

(0-15°/100 ft) in soft or hard formations

Drill lateral/tangent sections in closed loop IH mode

Steer through hard/soft inter bedded stringers

OH sidetracking

Vertical hold

PowerDrive Archer Features and Benefits

Increases bit on bottom time by versatile directional capability:• KO, delivering consistent and reliable DLS

• Deliver any type of well path in soft/hard formations

• Open hole sidetracking

• Penetrate hard layers

Unique Hybrid Steering

• Internal pads and higher operating parameter ensures higher reliability

• Near bit GR/D&I for better well placement

• Modular compactness for ease of transport and servicing

Driller’s Tool

• Improved footage per day

• Reduced LIH risks

• Better bore hole quality

• No annular restrictions, can back ream

Fully Rotating

Summary

Over 81,000ft and 4,500 hrs on Field test

Tool MTBF at 1600Hrs

Proven :

– To Kick off from vertical

– Drill curves at different DLS

– Landed all wells to target TVD

– Drilled laterals in close loop inclination hold
