Web16 Jul 2024 · Moreover, Lambda-Rho and Mu-Rho cubes are created using multi-attributes after applying post-stack inversion on 3D seismic data to predict the presence of gas. Since P-impedance inversion is sensitive to lithology, fluid, and porosity, it is difficult to discriminate each effect from the others and the results will be ambiguous. In order to ... WebPre-stack inversion represents one step beyond post-stack inversion in that not only the profile of acoustic impedance can be inferred from seismic data, rather a set of elastic parameters is estimated from pre-stack data (i.e., angle gathers) using the information contained in the so-called AVO (amplitude versus offset) response. peggy the doll facts
