Abstract
Quantifying the effectiveness of any AVO technique<br>has always been a concern for progressive<br>geoscientists assessing and modeling reservoirs. This<br>paper compares three major AVO-based attributes<br>and their applications. Elastic impedance, lambdamu-<br>rho, and conventional intercept-gradient AVO<br>techniques are compared for various angular<br>apertures and well availability using a 3D prestack<br>seismic model. The effectiveness of each technique<br>is determined by comparing the apparent reservoir<br>extent to the known reservoir extent.
