Seismic Acquisition Geophysical Prospecting using

2020-2-25 · 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 to arrive at sensitive recorders (geophones).

Seismic Prospecting an overview ScienceDirect Topics

Surface waves are of limited significance in seismic prospecting. They move along the ground at a slower velocity than do body waves. The surface disturbance is termed ground rolland may include Rayleigh and other vertical and horizontal modes of propagation. Seismic surveying is largely concerned with the primary Pwaves.

Seismic prospecting has its basis in the classical physical principles of transmission, reflection, refraction, and scattering of elastic waves in a layered solid half-space. The great increase in application of the methods and the continual effort to improve them since 1925 have resulted in elaboration and refinement of instruments, field methods, and interpretation techniques.
