Overburden Pressure Formula
The following formula is used to calculate the Overburden Pressure.
Po = .052 * pb * D
- Where Po is the Overburden Pressure (psi)
- pb is the formation bulk density (ppg)
- D is the true vertical depth (ft)
How to Calculate Overburden Pressure?
The following two example problems outline how to calculate the Overburden Pressure.
Example Problem #1:
- First, determine the formation bulk density (ppg). In this example, the formation bulk density (ppg) is given as 150.
- Next, determine the true vertical depth (ft). For this problem, the true vertical depth (ft) is given as 500.
- Finally, calculate the Overburden Pressure using the equation above:
Po = .052 * pb * D
Inserting the values from above and solving the equation:
Po = .052 * 150 * 500 = 3900 (psi)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
formation bulk density (ppg) = 1055
true vertical depth (ft) = 35
Entering these values yields:
Po = .052 * 35 * 1044 = 1900.08 (psi)
