The most accurate prediction of Productivity Index is based on numerical reservoir flow simulations but there are numerous proxy models covering popular categories of reservoir flow regimes, dynamic reservoir properties and well-reservoir contacts.
The most popular proxy model is the Dupuit PI @model which covers a very wide range of stabilised reservoir flow.
