Wave-induced-fluid-flow

This repository contains Python implementations of several analytical wave-induced fluid flow (WIFF) models for studying seismic wave dispersion and attenuation in porous rocks.

Main modules

• biot_gassmann.py Biot global flow and Gassmann models
• EMT.py Effective medium theory (EMT) related functions.
• squirt_flow.py Squirt-flow models and related calculations.
• wiff_layer.py Wave-induced fluid flow in layered porous media.
• wiff_layer_aniso.py WIFF model for anisotropic layered media.
• wiff_sphere.py Spherical inclusion / patchy-saturation WIFF models.
• utils.py Common utility functions used by different models.

Examples and tests

The following Jupyter notebooks are used to test the models and reproduce numerical examples:

• test_global_flow.ipynb
• test_layer.ipynb
• test_sphere.ipynb
