seismic prospecting sound waves

Seismic Acquisition Geophysical Prospecting using

Seismic acquisition is a geophysical prospecting method based on the principle that sound waves travel through the earth depending on the properties of the rock. A seismic wave is initiated by generating an energy wave using seismic vibrators at a known point (the shot point); records are made of the travel times and shape of the seismic waves

WAVE AMPLITUDES IN SEISMIC PROSPECTING 255 where p1 and P2 are the densities in the two media, while V 1 and V 2 are the corresponding velocities of longitudinal waves. In exchanging the indices in the formula one finds that the ratio is the same whether the wave is reflected at the upper or lower side of the boundary.

Method of exciting transverse waves in seismic prospecting

Nov 01, 1974· The method of transverse waves in seismic prospecting has a number of advantages in comparison with the method of longitudinal waves. Explosive methods of excitating transverse waves by which the directed effect of an explosion is created and used were tested. This wide testing of explosive sources became possible with the introduction of the method of selecting seismic waves according to

Exploring for oils. Exploring the Earth using earthquakes

Making waves: Rocks transmit seismic waves (i.e. seismic waves travel through them) but, wherever the waves go from one rock type to another, a reflected wave bounces back from the junction, like the wave that bounced back across the slinky. When sound waves are reflected like this they give an echo. Seismic prospectors make seismic waves that are sent out, bounce back and are detected by a

Seismic wave Engineering geology A seismic wave is a

A seismic wave is a vibration generated by an earthquake, explosion, or similar energetic source and propagated within Earth or along its surface. Earthquakes generate four principal types of elastic waves; two, known as body waves, travel within Earth, whereas the other two, called surface waves, travel along its surface. Seismographs record the amplitude and frequency of seismic waves and
