Title (EN) GELLING FLUIDS AND RELATED METHODS OF USE
(FR) FLUIDES GÉLIFIANTS ET PROCÉDÉS D'UTILISATION ASSOCIÉS
Abstract: front page image
(EN)Methods of acidizing a subterranean formation penetrated by a wellbore that include the steps of (a) injecting into the wellbore at a pressure below subterranean formation fracturing pressure a treatment fluid having a first viscosity and including an aqueous acid and a gelling agent of Formula (II): wherein R1 is (CxHy), wherein x ranges from 17 to 21 and y = 2x+1or 2x-1; R5 is hydrogen or -CH3; R6 is -CH2-CH2-CH2-; and R2, R3, and R4 are each -CH3; (b) forming at least one void in the subterranean formation with the treatment fluid; and (c) allowing the treatment fluid to attain a second viscosity that is greater than the first viscosity.
(FR)L'invention concerne des procédés d'acidification d'une formation souterraine pénétrée par un puits de forage qui comprennent les étapes consistant à (a) injecter dans le puits de forage à une pression inférieure à la pression de fracturation de la formation souterraine un fluide de traitement ayant une première viscosité et contenant un acide aqueux et un agent gélifiant de Formule II : où R1 est (CxHy), x étant dans la plage de 17 à 21 et y = 2x+1 ou 2x-1 ; R5 est un atome d'hydrogène ou -CH3 ; R6 est -CH2-CH2-CH2- ; et R2, R3, et R4 sont chacun -CH3 ; (b) former au moins un vide dans la formation souterraine à l'aide du fluide de traitement ; et (c) laisser le fluide de traitement atteindre une seconde viscosité qui est supérieure à la première.
