Adding relatively low molecular weight water-soluble friction loss reduction polymers to an aqueous fluid gelled with a viscoelastic surfactant (VES) increases the critical generalized Reynold's number at which the Fanning friction factor increases and friction pressure starts to increase rapidly. The water-soluble polymeric friction loss reduction additives lower surface pumping pressure in VES- gelled fracturing fluids for a given pump rate, thus lowering hydraulic horsepower (HHP) requirements for pumping fluids downhole, e.g. for hydraulic fracturing or frac packing treatments of subterranean formations.

L'invention concerne l'ajout de polymères de réduction de perte par frottement, solubles dans l'eau, de masse moléculaire relativement faible, à un fluide aqueux gélifié par un agent tensioactif viscoélastique (VES) permettant d'augmenter le nombre de Reynolds généralisé critique auquel le facteur de frottement Fanning augmente et la pression de frottement commence à augmenter rapidement. Les additifs polymériques solubles dans l'eau de réduction de perte par frottement abaissent la pression de pompage de surface dans les fluides de fracture gélifiés par VES pour une vitesse de pompage donnée, abaissant ainsi les exigences de puissance hydraulique en chevaux (HHP) pour le pompage de fluides dans le puits, par exemple pour des traitements de formations souterraines par des fracturations hydrauliques ou un compactage combiné à une fracturation.
