n: transverse or longitudinal seismic waves transmitted in the interior of an elastic solid or fluid and not related to a boundary surface.

determines formation seismic wave velocities over specific intervals. Measurement is made of travel time from surface to downhole geophones.

n: The acute angle at which a raypath impinges upon a line normal to an interface, such as a seismic wave impinging upon strata. Normal incidence is the case in which the angle of incidence is zero, the wavefront is parallel to the surface and its raypath is

primary or compression wave. A seismic body wave that involves particle motion, alternating compression and expansion. It is the fastest seismic wave.

n: The ways be used to detect the formation pressure by the different velocity of anthropic seismic wave in the formation.

n: shock wave generated by an earthquake or.explosion.
