Pore Pressure of Shale Traugott Calculator

Ppsh=z[Svz−(Svz−Phydroz)(RoRn)1.2]P_{psh}=z\left[\frac{S_v}{z}-\left(\frac{S_v}{z}-\frac{P_{hydro}}{z}\right)\left(\frac{R_o}{R_n}\right)^{1.2}\right]

Enter the required inputs, confirm the units, and run the calculator to solve P_psh. Review the formula source and assumptions before using the result in engineering work.
