Agitator ™ Systems

Benefits - Agitator and AgitatorPLUS Systems• Increases sliding and rotary ROP

• Increases the length for extended reach drilling

• Reduces downhole friction and stick-slip

• Improves weight transfer and toolface control

• Prevents weight stacking and drillstring buckling

• Extends bit life

The compression and friction forces that affect your drillstring downhole limit weight-on bit, reduce ROP, and can cause premature bit failure.

With the largest fleet and the most experience, our Agitator™ and Agitator™PLUS systems have provided unparalleled friction reduction through axial oscillation. These solutions have been proven by operators around the world in nearly 50,000 runs, and we provide support at 45 global service facilities. With an Agitator™ system in your drillstring, you can drill faster and drill farther.

Proven Friction Reduction, Improved Weight Transfer

Agitator™ SystemThe Agitator system reduces friction and improves weight transfer by

gently oscillating your drillstring. It also reduces fluctuations in weight

transfer to the bit. The result is enhanced toolface control, reduced

stick-slip, extended reach, and improved efficiency in all modes of

drilling, including rotary applications.

Since the oscillations are low magnitude and only affect the longitudinal

axis of your drillstring, the Agitator system does not cause the harmful

lateral vibrations that can damage downhole tools. The Agitator system

is compatible with all MWD systems.

 

Proven Applications• Directional drilling

• Wellbore intervention

• Fishing operations

Agitator™PLUS SystemThe AgitatorPLUS system combines our Agitator oscillation tool with

a special low pressure shock tool. Optimized to function as a unified

system, we have configured the AgitatorPLUS system with an overall

pressure drop of 300–400 psi. This allows you to maintain higher flow

rates, run the AgitatorPLUS system on rigs with limited pump pressure

capacity, and run two Agitator systems simultaneously in your BHA.

 

Proven Applications• Operations with limited pump capacity

• Extended reach drilling

• Tortuous well profile
