SLICK PULSAR
SLICK is a drop in replacement servo pulser module that is fully compatible with the QDT-Tensor MWD system. It incorporates cutting edge technologies to achieve significant improvements in performance.
SLICK features a rotary shear valve that provides exceptional performance in high solids and high LCM environments while simultaneously minimizing the pressure loss through the servo module, thus allowing greater forces to be imparted to the main valve assembly. The wiping action of the rotary shear valve clears away any compacted debris and ensures unobstructed flow through the system.
SLICK decouples the hydrostatically compensated section of the servo pulser from the pulser driver module with a high torque magnetic coupling assembly. This eliminates failures of the driver module caused by corrosion, fluid invasion and gas invasion while simultaneously reducing frictional losses and increasing system robustness. The pulser driver module features a compact, modular and rugged and features built in event logging and performance tracking capabilities.
SLICK has low power consumption and significantly increases the battery life of the QDT-Tensor MWD system. Nominal power consumption of the SLICK servo pulser system is approximately one third of the original QDT-Tensor servo pulser.
The combination of the rotary shear valve, magnetic coupling drive mechanism and robust control electronics enables SLICK to have exceptional performance in the deep, hot and hostile environments encountered in today’s challenging drilling programs.
