Methods which include hydrating a crystalline polymeric material in a first liquid medium, precipitating the polymeric material to form an amorphous polymeric material, and combining amorphous polymeric material with a second liquid medium to form a treatment fluid. Alternative methods include hydrating a crystalline polymeric material in a first liquid medium, precipitating the polymeric material to form a lower crystalline form of the polymeric material, and combining the lower crystalline form of polymeric material with a second liquid medium to form a treatment fluid.
Procédés consistant à hydrater un matériau polymère cristallin dans un premier milieu liquide, à précipiter le matériau polymère pour former un matériau polymère amorphe, et à combiner ce matériau polymère amorphe avec un second milieu liquide pour former un fluide de traitement. D'autres procédés consistent à hydrater un matériau polymère cristallin dans un premier milieu liquide, à précipiter le matériau polymère pour former une forme cristalline inférieure du matériau polymère, et à combiner cette forme cristalline inférieure du matériau polymère avec un second milieu liquide pour former un fluide de traitement.
