<p>Fracturing fluid comprising, in solution in water, a proppant and an associative amphoteric polymer, the said polymer having a molecular weight of at least 1 000 000 g/mol and comprising: 0.01 to 10 mol % of at least one cationic monomer derived from acrylamide, from 0.09 to 89.99 mol % of at least one anionic monomer, and from 10 to 99 mol % of at least one nonionic water-soluble monomer. Fracturing process using the fluid.</p> |
