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 estimates of the usual coefficients (e.g., intercept, gradient). The method will be illustrated for class I reflectors using large reflection angles. A real data example shows the applicability of the proposed approach.
