... their influence on the frequency-dependent inversion and to find out which technique provides the best inversion results. Three AVO approximations were then used to compute eight different frequency-dependent attributes to detect the dispersive reflection from the gather. The results showed that it is vital...

... ABSTRACT We propose a new method for constructing amplitude-versus-offset (AVO) approximations. This method is based on a framework that seamlessly spans the Born and Rytov approximations to seismic wave propagation, and which can be customized to produce either Born-like, Rytov-like, or mixed...

... Summary We propose a method, namely OptAVO to build enhanced linear AVO approximations. The basis functions of the approximation are orthogonal and their coefficients represent a new set of AVO attributes. These attributes can directly be used for AVO classification or to obtain better...
