Introduction

We present DiffraPy, a Python based software for processing and imaging seismic diffractions.

We show how to run the functions in the .ipynb examples, i.e., interactive Jupyter Notebooks.

Try creating your own!

We highly recommend to use Anaconda (https://www.anaconda.com/).

All main dependencies are listed below:

python version = 3.8.8
obspy = 1.3.0
numpy = 1.19.5
scipy = 1.8.0
matplotlib = 3.5.1

Homogeneous model

In the notebook Homogeneous_VelocityModel_Example.ipynb, you can find the example of a toy model for a general understanding of the method.

Heterogeneous model

In the notebook Heterogeneous_VelocityModel_Example.ipynb, you can find the example of a complex synthetic model based on the SEG/EAGE salt model.

SEGY files

If you want to apply the seismic diffractions method on a field data, we demonstrate how to read .segy files in the notebook Writing_Reading_Segy_File_Example.ipynb. You can also convert the synthetic data generated in the examples to .segy files.
