The geophone in seismic survey is the instrument used to transform seismic energy into an electrical voltage. It ordinarily responds to only on the component of the grounds displacement, velocity, or acceleration associated with the passage of a seismic wave. For a seismic reflection survey with P-waves, this is the vertical component.   A motion-sensitive […]

Multichannel analysis of surface waves geophones is designed to respond to a certain frequency (e.g.4.5Hz,8Hz,14Hz and 40Hz). While a 4.5Hz geophone is used for most depth. Multichannel analysis of surface waves seismic survey that needs to cover a long linear path quickly may utilize a land streamer. 4.5Hz Geophone Commonly Used Land Streamer One common […]
