This tool applies a standard formula from the relevant domain. The computation is deterministic — given the same inputs, the result is always identical. The formula accounts for the primary variables that determine the output.
φ(z) = φ₀ × e^(−c×z)The calculation requires: Surface Porosity φ₀, Compaction Coefficient c, Burial Depth. Each parameter contributes to the final result according to the formula above. Accuracy depends on the precision of your input measurements.

Check the expected unit for each input field (shown as suffix). Converting between imperial and metric units before entering values prevents calculation errors.
When a formula combines multiple measurements, all inputs must use compatible units. Convert everything to the same system (metric or imperial) before calculating.
Model porosity decrease with burial depth using exponential compaction curve. Free compaction porosity decline tool for compaction, porosity, and more. It applies the calculation formula (φ(z) = φ₀ × e^(−c×z)). For example: φ₀=45%, c=0.0005/m, 3000 m — A typical use case demonstrating the calculator with representative values.
