CA 2522542

Methods for treating subterranean formations, hydrophobically modified polymer compositions and fracturing fluid compositions containing hydrophobically modified polymer are provided. The hydrophobically modified polymer compositions wherein a plurality of hydrophobic groups are formed on the polymer, are basically comprised of water, a charged polymer, and surfactant. The surfactant has a charge opposite to that of the polymer and is capable of forming ion-pair associations with the polymer.

L'invention concerne des procédé permettant de traiter des formations souterraines, des compositions polymères comprenant des polymères modifiés de manière hydrophobe et des compositions de fluide de fracturation comprenant des polymères modifiés de manière hydrophobe. Lesdites compositions polymères comprenant des polymères modifiés de manière hydrophobe, selon lesquelles une pluralité de groupes hydrophobes sont formés sur le polymère, sont généralement constituées d'eau, d'un polymère chargé, et d'un tensioactif. Le tensioactif présente une charge opposée à celle du polymère et peut former des associations de paires d'ions avec le polymère.
