Abstract

Summary

Microseismic source localization is posed as a linear inverse problem. A finite difference code that solves the acoustic wave equation in heterogeneous media is utilized to define a forward operator that maps subsurface sources to pressure measurements acquired on the surface of the earth. The inversion process entail inverting the aforementioned operator with the assistance of a group sparsity regularization term that promotes source focusing. By adopting group sparsity, we guarantee the retrieval of a sparse spatial distribution of sources with smooth temporal signatures.
