Fracturing fluid comprising, in solution in water, a proppant and an associative amphoteric polymer, the said polymer and comprising:n 0.01 to 10 mol % of at least one cationic monomer containing a hydrophobic chain, from 0.09 to 89.99 mol % of at least one anionic monomer, and from 10 to 99.9 mol % of at least one nonionic water-soluble monomer, the total amount of monomer being 100 mol %. nn Fracturing process using this fluid. |
