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…
Verification of reciprocity in anisotropic poroelastic wave simulation using symmetric Strang splitting
Morten Jakobsen, Jose Carcione
Poroelastic wave simulations are important for many applications relating fluid flow and wave characteristics in porous rock formations. Reciprocity is a key physical property of w…
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…
Efficient scattering approach to seismic full-waveform inversion in anisotropic elastic media with variable density
Kui Xiang, Morten Jakobsen, Ujjwal Shekhar +2
This paper introduces a novel matrix-free approach for full waveform inversion in anisotropic elastic media, incorporating density variation through the utilization of the distorte…
A History-dependent Dynamic Biot Model
Jakob S. Stokke, Morten Jakobsen, Kundan Kumar +1
In this work, we consider a fully dynamic Biot model that includes memory effects due to evolving permeability. Time integrals are used to account for the change in structure. We p…
