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. You can find the full list on my website at: http://andymcdonald.scot/python-and-petrophysics

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

Binder button will be added to all new new notebooks going forward
