S T - 5 S h o c k T o o l P l a c e m e n tFor optimal tool performance, the Cougar ST-5 Shock Toolshould be placed immediately above the bit to minimize theamount of unsprung mass below the tool. Improper locationin the bottom hole assembly can cause severe damage to theshock tool.

The Cougar ST-5 Shock is best located in a position where it isexposed to a minimum of side loading or bending stress. Theshock tool should have the equivalent amount of stabilizationon either end, if it is stabilized at the lower connection, thereshould be stabilization within 30 feet of the upper connection.

O p e r a t i n g f e a t u r e s Bi-directional spring action allows the Cougar ST-5 to

compress or extend to compensate for any combination of bitweight or pressure drop across the bit.

The advanced engineering of the Cougar steel springs providesexcellent vibration dampening.

Pressure-balanced seal system keeps the tool from closingunder hydrostatic pressure.

Innovative internal design increases rotating life. Standard operating temperatures up to 225F (93C.)

Special seals are available for operating temperatures up to450F (232C.)

The hydrostatically balanced ST-5 has a special floating pistonto prevent closing under deep drilling conditions.

Bellville disc springs provide a linear spring rate high loadcapacity, and low hystereisis.

The ST-5 body connection are kept to a minimum to reducepotential failures.

S t r e n g t hThe ST-5 is constructed of heat-treated, vacuum degassed,high-purity steel. We use only the highest-grade steel, andevery bar of steel is tested by independent metallurgicallaboratories to verify its quality. As a result, the ST-5 hasthe inherent tensile and torsional strength to handle thelongest and toughest drilling programs.
