Witryna29 lis 2024 · However, from a mathematical point of view, seismic impedance inversion is an inverse problem and is ill-posed. Due to the limitations of incompleteness, noise, and wavelet band limitations of the observed data, multiple geological models can usually be obtained to match the observed data. WitrynaSeismic inversion refers to the process of estimating the properties of underground rocks using surface acquired seismic data. Classical seismic inversion methods usually start with a smooth model of underground properties, and then perform forward simulation to generate synthetic seismic data.
