ST5 Drilling Shock Tool

Heavy-Duty Protection. Superior Performance.


Overview

The Challenge

Bit bounce, shock, vibration and other erratic drilling conditions damage your bit and BHA and harm your overall drilling performance. This can lead to increased drilling times and associated costs.

The Solution

The Cougar ST5 drilling shock tool incorporates a configurable belleville spring stack with the highest grade oil sealed by available high temperature seals. It’s designed with carbide-coated components for the best performance in any fluid type, from high content brine to OBM.

Cougar configures each drilling shock tool for your rig and your conditions, with both tricone and PDC bits. Whether it’s a soft or stiff configuration, single or dual-acting stroke, we’ve got you covered with precise tools optimized for your application.

Drilling Shock Tool Benefits

Cougar Drilling Solutions Shock Tool

  • Extends bit life
  • Increases parameter consistency
  • Reduces shock and vibration at the BHA
  • Allows consistent weight transfer for optimal bit engagement
  • Reduces vibrations to the top drive, eliminating associated damages and costs

Instructions

ST5 Shock Tool Placement

For optimal tool performance, the Cougar DS ST5 Shock Tool should be placed just above the bit to minimize the amount of un-sprung mass below the tool. Please note: Improper location in the bottom hole assembly can cause severe damage to the shock tool.

The Cougar ST5 Shock should be placed where it is exposed to minimum side loading or bending stress. The shock tool should have the equivalent amount of stabilization on either end. If it is stabilized at the lower connection, there should be stabilization within 30 ft. of the upper connection.
