Petropedia explains Productivity Index (PI) Productivity Index is one of the important parameters tested once the well is complete and ready for production. It is the ratio of total flow rate of the liquid to the drawdown pressure and can be written in the form of equation as: J = Qo / Pr – Pwf = Qo / delta P.

Production Index (PI) Maturity of a homogeneous source section can be accessed from the production index (PI). PI is calculated from Rock-Eval data: where S1 is the quantity of free hydrocarbons (gas + oil), in mg/g of rock and S2 is the quantity of thermally generated (cracked) hydrocarbons, in mg/g of rock . 1 How to apply PI. Petropedia explains Productivity Index (PI) Productivity Index is one of the important parameters tested once the well is complete and ready for production. It is the ratio of total flow rate of the liquid to the drawdown pressure and can be written in the form of equation as: J = Qo / Pr – Pwf = Qo / delta P. What Is Industrial Production Index? The industrial production index (IPI) is a monthly economic indicator measuring real output in the manufacturing, mining, electric and gas industries, relative productivity index (PI) English | Español A mathematical means of expressing the ability of a reservoir to deliver fluids to the wellbore. The PI is usually stated as the volume delivered per psi of drawdown at the sandface (bbl/d/psi). The relationship between the dimensioned productivity index (PI) and the dimensionless J D of an oil well is simply (3.42) q p − p w f = k h α r B μ J D , where the constant α r is the familiar 141.2 in the traditional oilfield units or 18.4 if q (m 3 /d), p (atm) and h (m).
