The intersection of the IPR curve and the VLP curve gives what result?

• A. Flow stability
• B. Well deliverability
• C. Surface pressure
• D. Cumulative production

Answer: (B)

The actual production rate is set by the point where reservoir capacity and surface lift capability meet. The IPR curve shows how much fluid the reservoir can deliver at a given bottom-hole pressure, while the VLP curve shows how much flow the surface equipment can handle at a given surface pressure (or head). Where these two curves intersect, the reservoir and the surface system agree on a single flow rate and a corresponding bottom-hole pressure—the operating point. That rate is the well deliverability, the true production rate achievable under current conditions. If one curve lies below the other everywhere, the corresponding constraint dominates, but at the intersection both limits are active and define the deliverable rate.
