This paper describes a generic methodology for using 4D seismic as a steering mechanism in an automated procedure for performing history matching of reservoir flow models. Several key technology components are used in the history matching and will be presented in this paper, amongst them seismic attribute analysis and classification, reservoir simulator technologies, domain transformation algorithms as well as the optimisation algorithms that administrate the history matching process. A case study where the algorithms have been successfully applied will be presented in the paper.
Time lapse reservoir data provides the characteristics of change of the reservoir properties over the period of time between consecutive measurements. This data may be obtained using a range of different techniques, including data gathered from several independent well measurements, seismic data, the knowledge of production rate and the gas or water injection rates.
