Abstract:
The present invention relates to a fracturation fluid comprising at least one propping agent and at least one water-soluble (co)polymer prepared from the hydrated crystalline form of 2-acrylamido-2-methylpropane sulfonic acid and/or at least one of its salts. The invention relates to a process to prepare said fluid, and to a hydraulic fracturation process using said fluid.
