Well log plots are a common visualization tool within geoscience and petrophysics. They allow easy visualization of data (for example, Gamma Ray, Neutron Porosity, Bulk Density, etc) that has been acquired along the length (depth) of a wellbore.

I have previously covered different aspects of making these plots in the following articles:

• Displaying Lithology Data on a Well Log Plot Using Python

• Displaying Logging While Drilling (LWD) Image Logs in Python

• Enhancing Visualization of Well Logs With Plot Fills

• Loading and Displaying Well Log Data

In this article, I will show how to combine these different methods into a single plot function that allows you to easily reuse the code with similar data.

For the examples below you can find my Jupyter Notebook and dataset on my…
