Abstract

In this article, the effect of L1 error approximation has been studied in the context of f - x finite impulse response (FIR) extrapolation filter. The idea is to obtain a sparse error between the ideal and approximated wavefield extrapolator. It is shown that L1 error approximation approach not only offers a solution to the high passband error but also accommodates wavefields propagating with wider angles. The efficiency of the proposed approach has been shown by extrapolating the challenging SEG/EAGE salt velocity model via depth extrapolators designed by the L1 error approximation.
