The oil and gas industry uses the Production Engineering Calculator as a valuable tool to determine the Productivity Index (PI) of a well. PI is a crucial metric that measures the well’s ability to produce oil or gas under different pressures. It is expressed in barrels per day per pound per square inch (bpd/psi).
The calculator takes into account three primary parameters:
- Q (Flow Rate): This is the rate at which fluids (oil, gas, or water) are produced from the well. It is measured in barrels per day (bpd).
- Pwf (Wellbore Pressure): This is the pressure inside the wellbore and is measured in pounds per square inch (psi).
- Pwf_i (Initial Wellbore Pressure): This is the initial pressure at the beginning of the well’s production life, also measured in psi.
The Production Engineering Calculator uses the formula:
PI = Q / (Pwf - Pwf_i)
This formula provides a crucial metric for production engineers to optimize well performance and make informed decisions.
General Terms People Search For
To help you use the Production Engineering Calculator more easily, we have provided a table of some commonly searched terms related to production engineering.
Term | Description |
---|---|

Gas-Oil Ratio (GOR) | The ratio of produced gas to oil. |
Example of Production Engineering Calculator
Let’s put the Production Engineering Calculator to work with an example. Suppose you have a well with the following parameters:
- Flow Rate (Q): 500 bpd
- Wellbore Pressure (Pwf): 300 psi
- Initial Wellbore Pressure (Pwf_i): 100 psi
Using the formula:
PI = 500 / (300 - 100) = 5 bpd/psi
The Productivity Index for this well is 5 bpd/psi. This means that for every pound per square inch of pressure drop, the well produces 5 barrels of oil per day.
Most Common FAQs
