Official reproducible material for SiameseFWI: A Deep Learning Network for Enhanced Full Waveform Inversion - Omar M. Saad, Randy Harsuko, and Tariq Alkhalifah

Project structure

This repository is organized as follows:

• 📂 asset: folder containing logo;
• 📂 data: folder containing Marmousi2 and overthrust models data;
• 📂 utils: set of common function to run FWI;
• 📂 Model: containing Siamese network;
• 📂 results: containing the reconstructed velocity model using SiameseFWI;
• 📂 deepwave-old: containing the old version of the DeepWave package.

Notebooks

The following notebooks are provided:

• 📙 SiameseFWI_Marmousi.ipynb: the main notebook performing the SiameseFWI for Marmousi model;
• 📙 SiameseFWI_overethrust.ipynb: the main notebook performing the SiameseFWI for overthrust model;
• 📙 SiameseFWI_bad_initial_Overthurst.ipynb: the main notebook performing the SiameseFWI for overthrust model; bad initial model;

Getting started 👾 🤖

• To ensure the reproducibility of the results, we suggest using the FWIGAN.yml file when creating an environment.
• Please install deepwave 0.0.8 version, which is used in this project.

Run:

./install_env.sh

It will take some time, but if you see the word Done! on your terminal you are ready to go.

Remember to always activate the environment by typing:

conda activate FWIGAN

To install the old version of the DeepWave package, navigate to the "deepwave-old" folder, and run:

cd ./deepwave-old/
python setup.py install

Disclaimer: All experiments have been carried on a Intel(R) Xeon(R) CPU @ 2.10GHz equipped with a single NVIDIA GEForce RTX 3090 GPU. Different environment configurations may be required for different combinations of workstation and GPU.
