Key words: filtration, core analysis, water shut-off, oil displacement.
The paper presents the results of water shut-off experiments with core samples of main oilfields of Tomsk region. Experimental investigation of residual resistance and oil displacement was conducted for terrigenious core samples at reservoir conditions. Comparative evaluation efficiency of water shut-off treatment presented.
