The Cougar Drilling Solutions Mech-Thruster™ is your best choice for enhanced directional and horizontal drilling performance. Pressure-balanced to provide smooth-flowing energy to the drill bit, it is available in several sizes and can be adjusted to any specification. With the Mech-Thruster™, bit and MWD life are extended and the rate of penetration is increased.
The parameters for running a Mech-Thruster™ are the same as standard assembly parameters. That means no changes in pump pressure, flow, weight on bit or speed. By utilizing hydraulic pressure, the Mech-Thruster™ provides a constant weight on the bit, allowing it to drill ahead — independent of the non-uniform motions of the drill string sticking and slipping as it moves forward.
When running with a motor, the Mech-Thruster™ can help increase the reliability of driveshafts and power sections by reducing the chances of stalling the motor. Software placements are available for the Mech-Thruster™, which use the given drilling parameters and selected locations in the BHA to ensure optimum performance.
The Cougar Mech-Thruster™ is the only tool of its kind. Used in various applications worldwide, the Cougar Mech-Thruster™ is capable of drilling through tough formation areas. It has proven dependability and strength on any terrain.
With the use of the Cougar DS Mech-Thruster™, reactive torque becomes more manageable, reducing the number of stalls, eliminating motor damage and reducing MWD failure. In many cases, the Cougar DS Mech-Thruster™ has made steering easier for directional drilling applications.
The Cougar Mech-Thruster’s™ adjustable spring rate and long stroke has made this tool an essential part of many drill strings. While running the Mech-Thruster™ downhole, there is less overall damage to the drill string components. The Mech-Thruster™ is known to increase bit life so you can keep the bit on bottom longer which means fewer trips. The Mech-Thruster™ has proven to increase ROP and can be placed virtually anywhere in the BHA. Time and time again, the Mech-Thruster™ performs and exceeds expectations.
