DIRECT

DIRECT 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.

DIRECT 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.

DIRECT eliminates the need for a pressure compensated section in the servo pulser module with the use of a proprietary high pressure low friction sealing system. This dramatically reduces maintenance and service cycle times and greatly increases system reliability.

These improvements are coupled to a compact, modular and rugged pulser driver with built in event logging and performance tracking capabilities.

DIRECT has incredibly low power consumption and greatly increases the battery life of the QDT-Tensor MWD system. Nominal power consumption of the DIRECT servo pulser system is approximately one fifth of the original QDT-Tensor servo pulser, and one half that of currently available products.
