seismic geophone (Geophones) services

  • Sismic surveys

    A seismic survey is based on an energy source that excites seismic (elastic) waves in the subsurface. The seismic waves propagate in the subsurface and are reflected or refracted in the interfaces between mediums, having a different seismic velocity. The reflected and refracted waves are recorded on the surface by an array of receivers ...

  • Seismic Refraction and Reflection Techniques Services

    In seismic refraction surveys, a very small seismic wave is generated in the ground by either a hammer or small explosive change. This wave is refracted in the subsurface and detected by a series of sensitive geophones deployed along the ground. By measuring the travel-times of the seismic waves, the nature of and depth to subsurface features can ...

  • Seismic Refraction Services

    Seismic refraction is a geophysical method used to determine the seismic compression-wave (P-wave) velocity structure of the subsurface. Seismic P-waves are generated on the surface, propagate through the soil and rock, and are recorded by geophones at known distances from the source. Since P-waves are the fastest portion of the seismic wave, they ...

  • Groundwater Survey

    One set of DC-4500 Ground-flow Locator includes signal receiver, electrode, geophones and seismic source. We use two geophones and four electrodes as signal receivers, one DC-4500 Ground-flow Locator as seismoelectric data collector, and Buffalo Gun as seismic source.

  • Downhole Shear Wave Velocity Services

    This method is a variation of the seismic refraction method employing a downhole tri-axial geophone and a surface energy source or a downhole source. The energy propagates from the source to the downhole tri-axial geophone and can be recorded as compression and/or shear waves. This method provides detailed layer velocity information and the data ...

  • Seismic Methods

    All seismic methods measure the travel-time and frequency of elastic waves as they propagate through the subsurface. The methods commonly used in shallow geophysics involve using an impact source (hammer, weight drop, explosive source) to generate the seismic wave and recording the arrival of the waves with a seismograph and a series of geophones. ...

  • Field Operation of The DC-4500

    Field operation of the portable DC-4500 is not complicated as shown in the photo but requires only careful attention to the proper assembly of the components. The electrodes and geophone are connected by a cable to the DC-4500 computer unit and placed on the ground. The seismic source is generated by either a mechanical impact such as a sledge ...

  • Land Seismic Surveys

    Land seismic operations are similar to marine operations in that the energy sources are acoustic energy generated using vibrators mounted on trucks or low-impact explosives placed in shot-holes which have been drilled by truck-mounted or portable drills.  The receivers are typically geophones, which are like small microphones pushed into the ...

  • Hazard Monitoring Services

    Monitor your site for potential ground-movement hazards from the very beginning. Micro-seismic events can lead to tremors, landslides and in extreme cases the possibility of earthquakes. It makes sense to develop a baseline record of ground movement before drilling commences and during exploitation. We can offer 24-hour a day site monitoring using ...
