Top Mount Pulser

Argus is Rime’s patented top mount pulser solution and is designed to provide exceptional performance in demanding drilling applications. Optimized to create large pulse amplitudes across a wide range of flow rates and mud weights, Argus allows for reliable mud pulse telemetry at very low pulse widths in deep and extended lateral drilling applications. 

Argus is a hydraulically assisted lifting knob style pulser and has very low power requirements due to the use of Rime’s patented rotary shear servo valve pulser design, the same technology employed in our proven Slick-HD servo pulser. The rotary shear servo valve design provides exceptional performance in high solids and high lcm environments. Argus minimizes pressure loss through the Slick-HD derived servo module, thus allowing for greater forces to be imparted to the main valve assembly, enabling faster pulse widths at high pulse amplitudes. The wiping and cutting action of the rotary shear valve clears away any compacted debris and ensures unobstructed flow through the system in the most challenging and contaminated environments. 

Argus is highly modular and shares most of its components with Rime’s Slick-HD pulser, including the pulser driver, motor and the high torque magnetic coupling assembly. Customers who already own the Slick-HD servo pulser can leverage their existing assets effectively to maximize their return on investment. Modifying a Slick-HD servo pulser to become the Argus top mount pulser requires very few parts and roughly an hour of time. 

Argus and its Slick-HD components are compatible with Rime’s Pulser Interface Box and pulser interface program providing extensive memory logging, performance tracking, analysis and reporting capabilities.
