Enter the injectivity (bbl/day/psi) and the pressure difference between injection and well bottom hole flow pressure (psi) into the Injection Rate Calculator. The calculator will evaluate the Injection Rate.
Injection Rate Formula
The following two example problems outline the steps and information needed to calculate the Injection Rate.
IR = I * dP
Variables:
- IR is the Injection Rate (bbl/day)
- I is the injectivity (bbl/day/psi)
- dP is the pressure difference between injection and well bottom hole flow pressure (psi)
How to Calculate Injection Rate?
The following steps outline how to calculate the Injection Rate.
- First, determine the injectivity (bbl/day/psi).
- Next, determine the pressure difference between injection and well bottom hole flow pressure (psi).
- Next, gather the formula from above = IR = I * dP.
- Finally, calculate the Injection Rate.
- 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.
injectivity (bbl/day/psi) = 500
pressure difference between injection and well bottom hole flow pressure (psi) = 30
IR = I * dP = ?
