【實用工具app】AVO*|最夯免費app-綠色工廠好玩App

AVO* is a simple amplitude vs offset modeling tool for geophysicists and seismic interpreters. The idea is to show the behaviour of amplitude with incidence angle at a single interface, based on the Aki–Richards equation and Shuey approximation, two widely-used approximations to the Zoeppritz equations.

Simply enter P-wave velocity and density for the two layers, and S-wave velocity if you have it. Then tap Curve to see the magnitude vs incidence angle curve, or Crossplot to see the AVO gradient vs intercept crossplot. You can also perform simple fluid substitution, call up the elastic moduli, or email your parameters to yourself or a colleague.

Note: you must be online to show the curve and crossplot graphics, because they are supplied by the Google Charts web API.
