However, for continuous variations of mobility and storativity within the swept region, a simple two- or three-region model may not be appropriate. A multi-region, composite reservoir model has been developed to study the effects of various trends of mobility and storativity variations, within the swept region, on well tests for composite reservoirs. The multi-region composite reservoir model has been used to analyze drawdown tests from reservoirs undergoing a thermal recovery process such as steam injection or in-situ combustion. Based on the mobility and/or storativity of these reservoirs, three zones may be identified for a reservoir undergoing a thermal recovery process. These zones are: a swept zone with the highest mobility and/or storativity, a transition zone with continuously changing mobility and/or storativity, and an unswept zone with the lowest values for mobility and/or storativity. This study is intended to investigate how representing these reservoirs by different numbers of regions affects the pressure behaviour analysis. It has been found that representing the transition zone by one region may generate pressure behaviours which may show higher contrasts in physical properties than what actually exist. Finally, this work is intended to demonstrate how storativity variation can affect significantly the results obtained from some reservoir characterization methods. It has been shown that reservoir characterization methods, in which mobility is considered to be the only variable affecting the pressure behaviour from a reservoir, will fail when there is a storativity variation in the reservoir.
