Fast and Reliable Assessment of a Reservoir Model Quality on the Basis of Dynamic Behaviour

The article presents the first successful industrial application of the Target Pressure and Phase Method (TPPM) on a reservoir with secondary gas cap and a compositional fluid model. The method can provide correct in- and outflow at the boundaries and at the well locations over the entire calculated time interval of reservoir operations, without modification of the static parameters, relative permeabilities or endpoint saturations. For 13 out of 21 wells of the field example a perfect match of three-phase rates was achieved. The TPPM helped to identify immediately and clearly static model-regions, which do not fulfil dynamic requirements and need modifications before a history matching process could start
