Learn how to convert pressure into equivalent mud weight in PPG as per following formulas.
1. Convert pressure in psi unit into equivalent mud weight in ppg by using feet as the unit of measurement
Equivalent Mud Weight, ppg = pressure in psi ÷ 0.052 ÷ True Vertical Depth (TVD) in ft
Example: pressure = 5000 psi true vertical depth = 8000 ft
Equivalent mud weight, ppg = 5000 psi ÷ 0.052 ÷ 8000 ft
Equivalent mud weight, ppg = 12.0 ppg
2. Convert pressure in psi unit into equivalent mud weight in ppg by using meters as the unit of measurement
Equivalent Mud Weight in ppg = Pressure in psi ÷ 0.052 ÷ True Vertical Depth (TVD) in meters ÷ 3.281
Example: pressure = 5000 psi
True Vertical Depth = 2500 meters
Equivalent mud weight, ppg = 5000 psi ÷ 0.052 ÷ 2500 m ÷ 3.281
Equivalent mud weight, ppg = 11.7 ppg
Please find the Excel sheet for converting pressure into equivalent mud weight.
