Archie's Law Explained
Archie's law is represented as:
$$ Sw = \\left( \\frac{a \\times Rw}{\\Phi^m \\times Rt} \\right)^{1/n} $$
Parameters:
- a: Tortuosity factor (often around 1).
- Rw: Resistivity of the formation water (measured in ohm-m).
- Φ: Porosity of the rock (a fraction; e.g., 0.2 for 20%).
- m: Cementation exponent, which accounts for the rock's pore structure.
- Rt: True resistivity from logging measurements.
- n: Saturation exponent.
The provided code computes Sw using given parameters. Try adjusting the values to see how saturation (Sw) changes. This hands-on approach will solidify your understanding of how each parameter influences the outcome.
