Application of AVO seismic inversion in hydrocarbon prediction

Prestack inversion is performed by combining AVO analysis and seismic inversion which are three dimensional, multi traces, and full scale optimized. Relevant data such as P wave and S wave impedance, velocity ratio of compressional to shear wave, and Poisson's ratio can be obtained. Combining with lithologic contribution probability chart, lithologic data can be obtained. It has shown good result after being used for lithology prediction and in situ hydrocarbon detection. Hence it is thought that this method can process various trace gather, is a new fluid and lithology prediction method.
