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.
