Title (EN) SELF DIVERTING MATRIX ACID
(FR) ACIDE MATRICIEL A DERIVATION AUTONOME
Abstract: front page image
(EN)A method is described for treating a subterranean formation with a low viscosity fluid system that contains a viscoelastic surfactant at a concentration too low to viscosify the fluid, but that is concentrated in the formation so that the fluid system gels. The fluid optionally contains a formation-dissolving agent. The fluid is used in matrix acidizing, acid fracturing, and diversion.
(FR)L'invention concerne un procédé permettant de traiter une formation souterraine avec un système fluidique à faible viscosité qui contient un tensioactif viscoélastique dont la teneur est trop faible pour rendre le fluide visqueux, mais qui est concentré dans ladite formation de sorte qu'il se gélifie. Eventuellement, le fluide contient un agent de dissolution de la formation. Ledit fluide est utilisé dans l'acidification matricielle, la fracturation à l'acide et la dérivation.
