Frequency Domain Biot--Allard Equations for Isotropic and Anisotropic Poroelastic Media: Two-field formulations and iterative splitting
Morten Jakobsen, Jakob Seierstad Stokke, Kundan Kumar +1
We present a frequency-domain formulation of Biot's dynamic poroelastic equations with frequency-dependent dissipation (Biot--Allard) for anisotropic, heterogeneous media with memo…

Elastic waveform inversion for double-couple microseismic source estimation in vertically fractured transversely isotropic media
Ujjwal Shekhar, Einar Iversen, Florin A. Radu +2
Accurate characterization of microseismic events during fluid injection in sedimentary formations is essential to mitigate environmental risks. The source mechanism for microseismi…
