IPR is used to determine the relationship between which two quantities?

• A. Pressure drop and flow rate
• B. Bottom-hole temperature and depth
• C. Flow rate and bottom-hole pressure
• D. Porosity and permeability

Answer: (C)

An inflow performance relationship shows how the production rate of a well responds to the pressure at the wellbore. In practice, it maps flow rate to bottom-hole pressure (often the flowing bottom-hole pressure) to describe how much fluid can be produced at a given pressure at the well. This relationship is the basis for assessing reservoir deliverability and predicting production under different drawdown conditions. The other options don’t capture this direct link: pressure drop versus flow rate isn’t the standard IPR definition, bottom-hole temperature and depth are unrelated to production capability, and porosity with permeability describe rock properties rather than the well’s production behavior.
