SIG hydrophone streamers
Hydrophone streamers
SIG single to multi-channel seismic streamers
 
 
 
To provide a complete seismic system, SIG has developped its own hydrophone elements to mount into the streamers, and make high resolution arrays to work with sparker and boomer systems.

    Acceleration cancelling hydrophones
 
 
 
    environmentally friendly, filled with inert oil, no kerosene, no special shipping requirements
 
 
 
    modular arrays, interchangeable sections
 
 
 
    easily replaceable preamplifier in head compartment
 
 
 
    selectable modular gain (X20, 40, 80, 120)
 
 
 
    immersion adjusting air valve
 
 
 
The SIG 16 hydrophone streamers have small diameters of 31 mm, with a density of 1.05 on standard. The poluyrethane tubing keeps the section flexible over the years.
 
 
 
The configuration of the hydrophone arrays are customized, according to the needs of the geophysicists.

Increase the signal/noise ratio of the seismic records with a multi-channel coverage.
 
 
 
Our multi-channel streamers are dedicated to high and very high resolution seismics, with small diameter, short hydro spacings and group intervals.
 
 
 
Preamplification can be completed with a low-cut filter, depending on the energy source used.
 
 
 
The streamers are supplied neutrally buoyant, and can be ballasted to achieve the required towing depth, depending again of the emitted signal.

SIG seismic sound sources
 
The seismic sound source emits an acoustic signal into the water.
 
This acoustic signal penetrates into the seabed, and is reflected at each boundary between layers that have a different acoustic impedance.
Multi-tip sparker-electrodes 25 to 5000 joules
sparking electrode in salty water

These characteristic multi-tip sound-sources have been designed and optimized for the range of energies used with the sparkers, from 25 to 5000 joules.
 
 
 
These floating spark-arrays are planar,
 
easy to handle,
 
and very light weight.
 
 
 
No need for a heavy catamaran.
 
Can be used a small boat for littoral studies, as well as on large oceanographic vessels.
 
 
 
All the models of sparker-tips are interchangeable and can be mounted on the same floating high voltage cable.
