Abstract

A generic method for performing history matching of reservoir flow models using 4D seismic data is described. Several key technology components are used in the procedure, including seismic attribute analysis and classification, reservoir simulator technologies, domain transformation algorithms, as well as the optimization algorithms that guide the history-matching process. The novel 4D history-matching procedure was applied to the Tordis Field in the North Sea. As a result the transmissibilities of the fault network in the reservoir model were modified. In addition a production well was successfully side-tracked using results of the analysis from the time-lapse data.
