Using Python to Explore and Understand Equations in Petrophysics
A simple way to understand parameters to the Archie Water Saturation equation using Python
When you are learning a technical subject that has numerous equations and relationships, such as petrophysics, it can sometimes be difficult to understand how all of the parameters tie together.
Back when I started out in petrophysics many years ago, I used Excel to explore some common equations, such as the Archie Water Saturation equation. It was a great way to understand the impact of each of the parameters on the calculated result.
Within this article we will explore, with Python, three different ways that we can learn and understand the impacts of different parameters on an equation. The example equation used is the Archie Water Saturation (Sw) equation, which is used to calculate the amount of pore volume within a rock that is filled with water. This can then be used to infer how much hydrocarbon is present in the rock.
If you are not familiar with petrophysics, then the same workflow and examples can be applied to any equation of your choice. You may need to adjust the final example to show the data you want to see.
