Gel-forming METKA® system for selective water shutoff and enhanced oil recovery from Permocarbonic deposit in Usinskoye oilfield

Presented are the results on the study of a gel-forming METKA® system. The kinetics of gelation and rheological properties have been investigated in the system “methylcellulose–aqueous phase” in the temperature range of 20–250°C. The efficiency of applying the gel-forming METKA® system at filtration through water-saturated models and in the process of residual oil after-washing from two parallel columns with different permeability have been estimated.
