Incorporating attenuation effects into frequency-domain full waveform inversion from zero-offset VSP data from the Stokes equation

With the development of seismic exploration technology, the wave equations used to model the
characteristics of wave propagation are becoming increasingly complex. Generally, more than one
physical parameter is included in these wave equations, and merely inverting one parameter from
these equations cannot help to accurately understand the subsurface structure. To gain further
insight into the structure or oil- and gas-reservoir characteristics of the subsurface,
multi-parameter inversion is essential. In this study, density, velocity, and viscosity coefficient
are jointly reconstructed from the Stokes equation by frequency-domain full waveform inversion based
on zero-offset VSP data. The inverse problem is transformed to find the optimal solution to an
optimization problem, and the steepest-descent method is used. The sensitivities of the parameters
to the misfit function are analysed. Two inversion strategies, namely, the one-by-one parameter
inversion and joint inversion strat…
