Abstract
A method for evaluating well performance includes deriving a reservoir effective permeability estimate from data points in a production history, wherein the data points include dimensional flow rates and dimensional cumulative production, at least one of the data points has no sand face flowing pressure information; and deriving at least one reservoir property from the reservoir effective permeability estimate and the data points according to a well type and a boundary condition for a well that produced the production data.
