Oil Drilling Maximum Allowable Mud Weight Calculator
The online maximum allowable mud calculator allows you to calculate the Max Mud Weight. Enter the leaf of pressure, TVD and mud weight.
The Oil Drilling Maximum Allowable Mud Weight can be calculated using this free and offline application. You can also find dozens of other useful calculators.
Maximum allowable mud weight formula
Maximum Allowable Mud Weight is estimated in pounds per gallon (ppg). The formula is
ppg= (Leak of pressure) ÷ 0.052 ÷ (TVD) + (mud weight)
- Pounds per square inch (psi) is the unit of Leak of pressure.
- TVD is the true vertical depth and it’s unit is feet.
- The unit of mud weight is ppg.
Maximum allowable mud weight example
Let’s consider.
- Leak of pressure = 1140 psi
- TVD = 4000 ft
- Mud Weight = 10.0 ppg
Max Mud Weight (ppg) = 1140 psi ÷ 0.052 ÷ 4000 ft + 10.0 ppg
Max Mud Weight (ppg) = 15.52
