Polymer/rock interactions in polymer treatments for water-cut control

In this paper we study the adsorption of polymers bearing differently charged groups onto solid surfaces of siliceous nature. By means of static adsorption tests we show that the adsorption is dominated by the electrostatic interactions between the polymer molecules and the solid surface. We also show that both lithology and brine composition can strongly influence the adsorption behavior; such effects must be therefore carefully assessed before applying these treatments in the field.
