SPOTLIGHT ON TECH Weatherford OverDrive System The OverDrive system was developed to enhance the safety and efficiency of top-drive casing running and drilling operations. The system is made up of several distinct components, primarily the TorkDrive heavy duty and modular tools, which are mounted directly to the rig's top drive for making up and breaking out casing. These tools provide complete casing running and drilling capabilities, combining the functions of conventional power tongs, bails, elevators, thread compensators and fill-up circulation tools. The OverDrive system provides faster makeup and breakout with accurate thread compensation, the ability to switch between fill-up and circulating functions without repositioning the tool, high-volume circulation and fluid recovery, independent torque measurement, and reduced risk of operator errors with multiple safety interlocks. In addition to these improvements on conventional methods, the system takes operations to a new level by providing the ability to do what conventional tools cannot. These game-changing advantages include rotating and pushing down the casing while running to help prevent differential sticking, achieving high-speed string rotation with the top drive when drilling/reaming-with-casing and removing even more personnel from hazardous rig floor operations to remove risk.
