Gel Application in Water and Steam Diversion to Enhance Oil Recovery

Chen Zhao



This presentation shows that gel treatment helps to divert water and steam into low-permeability zones, increase oil production and reduce WOR and SOR; Gel application reduces heat loss and encrements water and steam relative mobility; Early gel treatment results in early incremental oil recovery and water cut reduction; Gravity is one of the dominant drive mechanisms of VWinj-HWprod steamflood; The production performance of VWinj-HWprod does not vary a lot with well distance.
