Definition - What does Resonant Frequency mean?
Resonant Frequency is a natural frequency generated by sound transmitting devices which are used for seismic studies. It is related to a term used in physics called Resonance. The sound is transmitted into the ground and the natural frequency of vibration is determined by the sensors or the sound receiving devices. By understanding the resonant frequency wavelength, the hydrocarbon presence is recorded.
Petropedia explains Resonant Frequency
In Physics terminology, Resonance is a phenomenon which occurs when any external force is applied on an object which brings it into oscillation with greater amplitude at certain frequency. This frequency is known as Resonant Frequency. There are various types of resonance phenomenon that occur, e.g.
- Mechanical resonance – It is used during construction of any building, towers or bridges.
- Acoustic resonance – The frequency generated is used during seismic studies for search of hydrocarbons and commercially viable reservoirs.
- Electromagnetic resonance – It is related to frequencies generated by electrical devices.
- Nuclear magnetic resonance – It is used in the field of nuclear energy.
