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

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

true vertical depth (TVD)= 2000 meters

Mud wt, ppg = 3583psi : 0.052 : 2000m : 3.281

Mud wt = 10.5ppg
