Petrophysics-Python-Series

⚠️ During 2023 this repo is planned to be restructured and tidied up. A number of notebooks are currently lacking commentary and will be updated gradually.

Petrophysics-Python-Series

This series of Jupyter Notebooks take you through various aspects of working with Python and Petrophysical data. A number of the notebooks are accompanied by either a Blog Post or a Medium article.

Check out the binder button below if you want to run these notebooks without needing to download them or install Python.
