The Turborunner is a high-speed reaming system that enables Completions teams to land first time at target depth and safeguard valuable completion assemblies. The Turborunner’s unique design combines high-speed rotational reaming with very low operating pressure and completely isolates the downhole assembly from the dynamics and vibrations of the reaming section. This unique feature also allows the turbine RPM to slow and even stall without any reactive mechanical torque or uncontrollable pressure spikes. Only the reamer shoe rotates so there is no need to rotate the completion string or low torque completion equipment. A rugged and reliable tool, the Turborunner ensures completions land on depth to access all reserves and maximize economic value, as well as significantly reducing any unplanned NPT associated with challenging downhole conditions.
