New aqueous fracturing fluid composition and fracturing method implementing the fluid

摘要

A fracturing fluid comprising, in solution in water, a propping agent and an associative amphoteric polymer, said polymer having a molecular mass of at least 1,000,000 g/mol, and comprising: 0.01 to 10 mol % of at least one cationic monomer derived from acrylamide, 0.09 to 89.99 mol % of at least one anionic monomer, and 10 to 99 mol % of at least one non-ionic water-soluble monomer. A fracturing method implementing the fluid.
