The Mechanical Thruster ™

Reduce Trips and Increase Reliability

The Mechanical Thruster provides a consistent force to the bit by balancing back pressure and WOB.

Overview

The Challenge

High shock and vibration, particularly in increasingly long laterals, can quickly drive up drilling costs. However, using aggressive bits to increase ROP and get quick performance gains can result in damages and associated trips for new bits and BHA components.

The Solution

The Mechanical Thruster reduces shock and vibration to increase reliability in BHA components and bits. It provides a consistent force to the bit by balancing hydraulics (back pressure below tool) and mechanics (weight on bit). This balance provides smooth energy transfer to the bit — even in erratic situations.

Our Process

As operators continue to push the limits in extreme conditions, Cougar’s Mechanical Thruster aims to reduce risks. We analyze BHA, well profile and drilling performance requirements and discuss specific objectives with your drilling team. This ensures you get optimal performance from the Mechanical Thruster.

Benefits

Cougar Drilling Solutions mechanical thruster in use

  • Decrease trips and associated costs due to damaged bits and BHA components
  • Reduce section times by gaining consistency in parameter envelopes from ROP to torque to differential pressure
  • Save money by reducing drilling times and reducing damage costs to bits and other components
