Summary:
The surface-consistent amplitude and deconvolution step is one of the main millstones of land processing. The amplitude scalars and the deconvolution operators are usually estimated through a cascading process. In this paper, we propose to simultaneously estimate both surface-consistent terms. Simultaneous Joint Inversion is a way to get more reliable surface-consistent attributes that obey the same general equations and result from a common inversion scheme. Simultaneous Joint Inversion also proves to be the simplest flow to estimate surface-consistent amplitude scalars and deconvolution operators.
