KGS--Petroleum: a primer for Kansas--Geophysical Exploration

Compressional waves, or P-waves, are the most common type of seismic wave used for reflection prospecting. P-waves propagating through the Earth behave similarly to sound waves propagating in air. P-waves generate echoes (reflections) when they come in contact with an acoustical contrast in the air or under the ground.

How is sound used to explore for oil and gas? Discovery

Seismic refraction gives more information about the layers. Sound pulses that enter the seafloor are both reflected and refracted (or bent) as they pass into different layers. The refracted sound pulse follows a complex path. With seismic refraction, the density of the layers can be determined.

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

Method of exciting transverse waves in seismic prospecting

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 the
