n: (PI) a well-test measurement indicative of the amount of oil or gas a well is capable of producing. It may be expressed as PI=q+(Ps-Pf) where.-- PI = productivity index (barrels/day or thousand cubic feet/day per pounds per square inch of pressure differential) q = rate of production (barrels/day or thousand cubic feet/day) Ps = static bottomhole pressure (pounds per square inch) P f = flowing bottomhole pressure (pounds per square inch).

a comparison of the productivity of a completion to the productivity of an ideal, undamaged open hole. Labeled PI or J.

n: pressure at the bottom of the wellbore when there is no flow of oil.
