Amplitude versus offset
TERM FOR REFERRING TO THE DEPENDENCY OF THE SEISMIC ATTRIBUTE, AMPLITUDE, WITH THE DISTANCE BETWEEN THE SOURCE AND RECEIVER
Amplitude Variation with Offset; Amplitude Versus Offset; Amplitude variation with offset
In geophysics and reflection seismology, amplitude versus offset (AVO) or amplitude variation with offset is the general term for referring to the dependency of the seismic attribute, amplitude, with the distance between the source and receiver (the offset). AVO analysis is a technique that geophysicists can execute on seismic data to determine a rock's fluid content, porosity, density or seismic velocity, shear wave information, fluid indicators (hydrocarbon indications).
