How is permeability calculated within this skill?

PetroPy includes built-in functions for the Timur and Coates equations, which estimate permeability (in mD) based on input porosity and water saturation curves.

Does PetroPy support shale volume corrections?

Yes, it supports various methods including linear, Larionov (old/young), and Clavier for shale volume estimation, which can then be used to correct porosity calculations.

What file formats does the PetroPy skill support?

The PetroPy skill primarily works with LAS (Log ASCII Standard) files, as it extends the lasio library for robust log data handling and manipulation.

Can I customize the Archie parameters for water saturation?

Yes, the skill allows you to define specific values for tortuosity (a), cementation (m), and the saturation exponent (n) to ensure calculations match your specific reservoir's characteristics.
