Seismic Instruments

SI Overview

Seismic Instruments builds next-generation seismic data acquisition systems for use on land. Our digital geophone technology and single-sensor recording approach are well suited for a range of applications — from small, lightweight systems for engineering uses to massive, high-density surveys for petroleum exploration and mining Seismic Instrument's system is also capable of non-seismic electromagnetic data acquisition.

High-Density Resolution Revolution

At Seismic Instruments, we believe the next revolution in seismic data quality will be based on single-sensor recording, and we are creating new seismic data acquisition systems that will make single-sensor recording cost-competitive with traditional systems.

Our primary goals at Seismic Instruments are to:

  • Equip our customers to improve their bottom lines by delivering higher quality data to their clients
  • Provide more efficient, productive tools for our customers to use in seismic data acquisition
  • Listen to our customers and respond to their needs

Wireless or Cable Configuration

Our new Smart Antenna Module® (SAM) enables the customer to configure either cable or wireless system configuration using the same building blocks.

  • Continuous recording mode on Compact Flash Card media
  • Optimized sensor per radio/battery ratio
  • GPS timing & synchronization
  • Radio communication
  • Paralell data downloading
  • Real time status and Quality Control monitoring
  • Multicolored LED Status Indicator

Single-Sensor Recording

Recording each individual sensor on a separate channel, and spacing the sensors closer than conventional group channels:

  • Avoids the irreversible filtering of data introduced by hardwired group forming
  • Allows improved signal-to-noise ratio by correcting for micro-statics, amplitude variations, dead sensors, etc. at the sensor level
  • Permits application of proper anti-alias protection to recover target bandwidth with less distortion

Digital Geophones

Our new SmartGeophone® outputs a digital signal directly from each phone:

  • Eliminates noise-prone analog wiring runs
  • Optimized for single-sensor recording
  • Advanced fault & tilt detection
  • Allows you to upgrade your existing analog geophones, if desired

Electromagnetic Capability

Using a connector based SmartGeophone®, SI's seismic system can be modified for electromagnetic (EM) recording:

  • Uses the same SI componets
  • System can be converted between electromagnetic and seismic
  • Built in amplification
  • Passive and active recording
