Paper presented at the SEG/AAPG International Meeting for Applied Geoscience & Energy, August 26–29, 2024
Paper Number: SEG-2024-4093855
... is predicted based on the results of elastic impedance inversion considering the compaction trend. In aspect of inversion method, we propose an improved Latin hypercube sampling strategy with mixed Gaussian distribution in the framework of Bayesian theory. This method is more in line with the prior probability...

Paper Number: SEG-2020-3422609
... Bayesian theory is widely used in various seismic inversion methods. At present, most seismic inversion aims to obtain the elastic parameters of the formation (such as wave impedance, lame constant, etc.), and then obtains the extent and lithofacies of the target geological body through manual...

... develop a AVO inversion method based on Bayesian theory in ray parameter domain, whose output is density, P-wave impedance and /. These elastic parameters have high precision, which are valuable input for reservoir characterization because they are related to lithology and fluid content of the reservoir...
