Neutrino™ Top Mount Pulser
High-Speed Mud Pulse Telemetry Pulser
Product Overview
The Neutrino™ Top Mount Pulser is a high-performance mud pulse telemetry solution engineered for continuous operation throughout the full wellbore. Designed to transmit high-frequency pulses in high LCM environments, it ensures uninterrupted data delivery and optimized operational efficiency in modern MWD/LWD and RSS applications.
Key Features
- Exceptional LCM tolerance up to 80 lbs/bbl
- High-speed pulse transmission: up to 10 bits/sec (with Neutrino™ telemetry)
- Multi-size compatibility: 4 3/4″, 6 3/4″, and 8″
- Field-configurable orifice and hole sizes in minutes
- Ultra-low power consumption and battery-efficient design
Applications & Drilling Scenarios
- High LCM wells and wells with severe circulation losses
- Real-time telemetry in complex bottom-hole assemblies
- Compatible with sonde-based MWD/LWD and RSS BHAs
Advantages Over Competitors
- Changeable orifice sizes on-rig, reducing NPT and servicing costs
- Delivers 4× more data with less power than legacy top-mount designs
- Field-proven rugged design for extended downhole durability
Compatibility
Fully integrates with Neutrino™ High-Speed Telemetry, sonde-based MWD systems, and RSS bottom-hole assemblies.
