U·Node 2

U·Node 2

Overview

The U·Node 2 is a robust and versatile nodal seismic recording system designed to modernize existing Sercel-equipped crews and provide flexible active or passive seismic acquisition. The system transforms legacy 408, 428, and 428XL FDU and DSU equipment into a modern nodal recording platform with GPS timing, removable memory, Wi-Fi, and cellular networking.

Each U·Node 2 supports up to 120 single-channel FDUs or 40 three-channel DSUs, with unlimited U·Node 2 units per spread. The system supports continuous recording for passive monitoring, triggered acquisition for shot records, and hybrid operation for large exploration or engineering projects.

U·Node 2 systems can operate as stand-alone nodal systems or supplement existing Sercel acquisition equipment. Real-time QC, field data offloading, Vscope 3 software, Observer monitoring, and SourceLink integration provide flexible acquisition and monitoring capabilities for both small crews and large projects.

Benefits

Extend the Life of Existing Sercel Equipment
  • Reuse existing FDUs, DSUs, and spread cables while upgrading crews to modern nodal acquisition capability.
Support Both Small and Large Crews
  • Use U·Node 2 for small engineering crews or expand to large high-channel-count exploration spreads.
Reduce System Cost
  • No annual software license fees and use of off-the-shelf PCs help reduce long-term operating costs.
Improve Real-Time Quality Control
  • Real-time noise monitoring, shot displays, and QC tools help crews quickly evaluate data quality in the field.
Increase Field Flexibility
  • Use cables, Wi-Fi, or cellular Ethernet connections for acquisition, QC, and data transfer.
Support Active & Passive Monitoring
  • The same U·Node 2 system can acquire Vibroseis, dynamite, and impulsive-source data while also supporting passive monitoring and event detection.
Simplify Engineering Seismic Deployment
  • Integrated sensor and FDU options reduce equipment count and simplify deployment for engineering and streamer applications.
