Learn how to convert pressure into equivalent mud weight into equivalent mud weight as per following formulas.
Convert pressure in psi unit into equivalent mud weight in ppg by using feet as the unit of measurement
Equivalent Mud Weight in ppg = pressure in psi ÷ 0.052 ÷ True Vertical Depth (TVD) in ft
Pressure = 5,000 psi
True vertical depth = 8,000 ft
Equivalent mud weight, ppg = 5,000 psi ÷ 0.052 ÷ 8,000 ft
Equivalent mud weight, ppg = 12.0 ppg
Convert pressure in KPa unit into equivalent mud weight in Kg/m3 by using meters as the unit of measurement
Equivalent Mud Weight in Kg/m3 = Pressure in KPa × 1000 ÷ True Vertical Depth (TVD) in meters ÷ 9.81
Pressure = 35,000 KPa
True Vertical Depth = 2,500 meters
Equivalent mud weight, kg/m3= 35,000 × 1,000 ÷ 2,500 ÷ 9.81
Equivalent mud weight, kg/m3= 1,427 kg/m3
Please find the Excel sheet for converting pressure into equivalent mud weight.
