Novel composition of aqueous fracturing fluid and fracturing process using the fluid. A fracturing fluid is provided comprising, in solution in water, a proppant and an associative amphoteric polymer, said polymer comprising: from 0.01 to 10% in moles of at least one cationic monomer containing a hydrophobic chain, of 0 0.09 to 89.99 mol% of at least one anionic monomer, and 10 to 99.9 mol% of at least one water-soluble nonionic monomer, the total amount of monomer is 100 mol%. Fracturing process that uses this fluid. |
