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. 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.
