Target-oriented shot-profile least-squares inversion could help improve amplitudes while keeping computational cost reasonable. We propose a methodology that combines first, an approximation of the scalar two-way wave equation operator by two one-way wave equation operators, and second, precomputed Green functions to the target. This methodology will allow to perform the shot-profile least-squares inversion without having to recursively compute the Green functions for all the depth steps at each iteration.
