A Literature Review on P-wave Velocities in Rock Under Compression
Ortiz, Julian M.
P-waves are acoustic waves propagated through geological mediums. P-wave velocities are increasingly being used in natural resource industries. The purpose of this paper is to present a literature background on the behavior of P-wave velocities in typical geological settings. P-wave velocities can be represented mathematically using the elastic moduli of the geological material, the density of the material, and the acoustic impedance of the material. The impact of environmental factors that can change the acoustic wave velocities are also addressed, including external pressures, humidity and temperature.
