Abstract

Summary

We tackle deconvolution within an inversion framework using the hyperbolic function for our data (i.e., reflectivity) misfit, thus enforcing sparse solutions.

This “sparse” deconvolution overcomes the minimum-phase assumption and converts the commonly seen three-lobed Ricker wavelet into an impulse. In addition, sparse deconvolution reveals the polarity of seismic events. Three datasets illustrate our findings.
