Abstract
A novel method for characterizing multilayer subterranean reservoirs comprising forming a single layer reservoir model representative of the flow parameters of the multilayer reservoir and developing a set of predicted flow rates from a numerical reservoir simulator. The predicted flow rates are scaled to form a set of dimensionless flow rates. Differences between actual reservoir flow rates and predicted flow rates obtained from the dimensionless flow rates, are minimized automatically to obtain estimates of flow parameters for each layer of the multilayer reservoir. Additionally, for a given set of flow parameters, the optimum injection and production well patterns as well as injection and production well operating conditions can be determined for producing hydrocarbon from the multilayer reservoir.
