Title (EN) TREATMENT FLUIDS FOR STIMULATION OF SUBTERRANEAN FORMATIONS
(FR) FLUIDES DE TRAITEMENT DESTINÉS À LA STIMULATION DE FORMATIONS SOUTERRAINES
Abstract:
(EN) Method comprising introducing a treatment fluid into a subterranean formation, the treatment fluid comprising a pseudo-crosslinking agent and an acidic viscoelastic surfactant (AVS) base fluid, wherein the treatment fluid has a pH of less than 5. The AVS base fluid includes a zwitterionic viscoelastic surfactant, an acidic constituent, and a polar solvent and the zwitterionic viscoelastic surfactant is present in an amount in the range of from about 0.001% to about 15% by weight of active surfactant of the AVS base fluid. The treatment fluid performs a subterranean formation operation.
(FR) La présente invention concerne un procédé comprenant l'introduction d'un fluide de traitement dans une formation souterraine, le fluide de traitement comprenant un agent de pseudo-réticulation et un fluide de base tensioactif viscoélastique acide (AVS), le fluide de traitement possédant un pH inférieur à 5. Le fluide de base AVS comporte un tensioactif viscoélastique zwittérionique, un constituant acide et un solvant polaire, et le tensioactif viscoélastique zwittérionique est présent en une quantité se situant entre environ 0,001 % et environ 15 % en poids du tensioactif actif du fluide de base AVS. Le fluide de traitement effectue une opération de formation souterraine.
