Converting Pressure into Mud Weight Basic drilling formula - Convert pressure, psi, into mud weight, ppg, using feet as the unit of measure Mud weight, ppg = pressure, psi + 0.052 + TVD, ft Example: pressure = 2600psi true vertical depth = 5000ft Mud, ppg = 2600psi + 0.052 + 5000ft Mud = 1O.0ppg Convert pressure, psi, into mud weight, ppg, using meters as the unit of measure Mud weight, ppg = pressure, psi + 0.052 + TVD, m + 3.281 Example: pressure = 3583 psi true vertical depth = 2000 meters Mud wt, ppg = 3583psi + 0.052 + 2000m + 3.281 Mud wt = 1O.5ppg
