SEISMIC CABLES

  Applications > seismic refraction/reflection

PASI offers a complete range of 12 or 24-channel seismic cables for refraction/surface reflection. We are able to create customised land streamers, perfect for facilitating fast surveys on all terrains where a vehicle can be used to drag geophones. For applications in the sea, rivers, basins or in wells, we can also make customised hydrophonic cables, suitable for all surveys in water.

Land streamer

 

Ideal solution for the rapid creation of long seismic lines on asphalt and dirt roads, or on unobstructed and vegetation-free land. Especially practical in all those situations where it is possible and advantageous to use transport means to "drag" the 12/24 channel spacing with the geophones already connected to the cable and mounted on special anti-tipping supports. 
Available on request with customized lengths and spacings.

hydrofone cables

 

Hydrophone cables provide for the use of hydrophones (waterproof pressure sensors, natural freq. 10Hz) instead of traditional geophones, thus allowing the implementation of expedited seismic surveys in lakes, rivers, wells (downhole & crosshole), etc. 
Since transverse waves are not transmitted in liquids, it will obviously be possible to detect only P waves (compression waves): for surveys in P&S wave wells, we recommend the 3D hole geophone Mod. GFA. 
Hydrophone cables are available with fully customized length, number of hydrophones and spacing.
