Water shutoff is an effective way to enhance oil recovery and lower water production. It is crucial to select target wells and target zones properly, otherwise, the effect of water shutoff may be disturbed. Traditionally, the job to select target wells and target zones is always done artificially and imprecisely, as a result, water shutoff does not perform as good as it can. This paper proposes a fuzzy method capable of optimizing the selection of target wells and target zones for water shutoff. This study plays a significant role in the technique of water shutoff.
