This paper is dedicated to the investigation of water- and oilswelling ability of the elastomeric material based on nonpolar ethylene-propylene rubber, modified by water swelling agents such as combination of copolymer acrylamide with potassium acrylate and sodium-carboxymethyl cellulose. It was found that the maximum volume increase of the sample recorded during it`s exposure in water and is equal 1250 %, in 10 % and 22 % aqueous solutions of sodium chloride is up to 280 % and 210 %, in oil and the Polyekonol-Flora drilling system 70 % and 80 %, respectively.
