(.465 psi/ft for salt water) (.433 psi/ft for fresh water) Now equating the water pressure to equivalent formation depth by: De = P/(S/D) Where. De = equivalent depth. P = pressure exerted by the water. S/D = overburden stress (depth of water + depth of interest (from chart) Programming this into a pocket calculator creates a accurate and ... ................
