Converting Pressure into Mud Weight
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 (TVD)= 5000ft
Mud, ppg = 2600psi : 0.052 : 5000ft
Mud = 10.0ppg


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 = 3583psi
true vertical depth (TVD)= 2000 meters
Mud wt, ppg = 3583psi : 0.052 : 2000m : 3.281
Mud wt = 10.5ppg
