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:

The data contained within is used to analyze and understand the subsurface, as well as identify potential hydrocarbon reserves. In my previous article: Loading and Displaying Well Log Data, I covered how to load a single LAS file using the LASIO library.

Borehole image logs are false-color pseudo images of the borehole wall generated from different logging measurements/tools. How borehole images are acquired differs between wireline logging and logging while drilling (LWD). In the wireline environment measurements are made from buttons on pads that are pressed up against the borehole wall and provide limited coverage, but at a high resolution.
