A technique for using production data to detect and quantify poorly drained compartments in gas reservoirs is described. The method is based upon a multi-compartment, tank-like model with well performance specified by an in-flow relationship. The technique is validated against a detailed finite element simulation. Field examples are presented illustrating the utility of the technique to improve reservoir development strategies.
