Enter the bottom hole resting pressure (psi) and the closure pressure (psi) into the Calculator. The calculator will evaluate the Net Pressure. 

Net Pressure Formula

NP = BHTP  - Pc


  • NP is the Net Pressure (psi)
  • BHTP is the bottom hole resting pressure (psi)
  • Pc is the closure pressure (psi)

To calculate Net Pressure, subtract the closure pressure from the bottom hole resting pressure.

How to Calculate Net Pressure?

The following steps outline how to calculate the Net Pressure.

  1. First, determine the bottom hole resting pressure (psi). 
  2. Next, determine the closure pressure (psi). 
  3. Next, gather the formula from above = NP = BHTP – Pc.
  4. Finally, calculate the Net Pressure.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

bottom hole resting pressure (psi) = 300

closure pressure (psi) = 250
