The Agitator creates gentle pressure pulses that have been proven to help you complete CT operations in extended reach wells.

The Agitator comprises a short Positive Displacement Motor section which powers a rotating valve. The rotor of the short motor section oscillates an upper valve plate with an off-centered hole above a static plate with a central hole. As the two holes align, the total flow area increases. Then, as the rotation continues, it partially restricts the static hole and decreases the flow area. The changing flow area creates pressure pulses which travel outward from the tool to break static friction with the wellbore.

Features:

  • Variable pressure pulses (Frequency and size of the pulses is directly proportional to the flow rate)
  • No downhole settings or adjustments required

Benefits:

  • Complete CT operations in extended reach wells
  • Reduces friction between the BHA and borehole
  • Reduces helical buckling
  • Improves weight transfer
