Compaction correction factor for sonic logs in shale lithology

Input(s)

$\Delta t_{s h}$: Adjacent Shale Bed's Transit Time (mu s/ft)

c: Shale Compaction Coefficient (dimensionless)

Output(s)

$C_{p}$: Compaction Correction Factor (dimensionless)

Formula(s)

$$ C_{p}=\left(\Delta t_{s h}\right) * \frac{c}{100} $$
