... law for steady state flow of an incompressible, single phase fluid and is called the Productivity Index (PI). However, this assumption is valid only above the bubble point pressure. Evinger and Muskat [1] , based on multi-phase flow equations showed that a curved relationship existed between flow...

... strategy. To determine the economical feasibility of drilling a well, petroleum engineers need reliable methods to estimate its expected productivity. Well productivity is often evaluated using the productivity index, which is defined as the production rate per unit pressure drawdown. We often relate...

... deliverability in the gas condensate reservoir often decreases from initial value. This deliverability loss has been investigated by conducting a series of compositional simulations with an actual reservoir data. The well gas productivity index (PI) at initial reservoir pressure of 4750 psia for a single-phase...
