Description:

The EZ Drill is a torsional and axial absorbing tool with a 16″ (5-1/4″ tool) to 17.5″ (7-1/4″ tool) axial stroke and 360° torsional movement. 

Torsional absorbing components work hydraulically and converts excessive torque to reduced WOB when needed. This is done by utilizing a helical spline. As the torque increases the helical pitch angle shortens the EZ Drill, temporary shortening will reduce the WOB. As the torque decreases it extends and maintains WOB. Extension is controlled by a hydraulic controlled assembly.

Maintaining a more constant WOB which decreases the stick slip effect. Reducing bit trips and motor stalls, while providing consistent drilling, keeping steady torque transferred to the bit and increasing bit life. Given the fact that bit life is greatly increased with the EZ Drill. This equates directly to saving on unnecessary trip time.

The EZ Drill will maximize ROP in all formations allowing the ability to drill longer and stronger. Providing less vibration on BHA equipment and minimizing pressure spikes in the drill string. This goes hand in hand with longer life to bottom hole components which in turn, will reduce damages to downhole tools.

Typically, 2000 Ft. Lbs. of torque will cause the mandrel to rotate 31° closing the EZ Drill by 1 inch. The EZ Drill is sprung in both extension and compression, meaning tool will function with minimal amount of torque or axial loading.

EZ Drill is complementary to working with an RSS tool and will assist with the efficiency and effectiveness of the RSS tool adding life to RSS tools. If Jarring through the tool is required, the extension force shoulders the tool for effective jarring action with no damage to the tool.
