Title (EN) IMPROVED FLUID EFFICIENCY FOR VISCOELASTIC SURFACTANT BASED FLUIDS WITH NANOPARTICLES
(FR) EFFICACITÉ AMÉLIORÉE D'UN FLUIDE POUR DES FLUIDES À BASE DE TENSIOACTIFS VISCOÉLASTIQUES PRÉSENTANT DES NANOPARTICULES
Abstract:
(EN) A method of treating a subterranean formation penetrated by a well comprises combining an aqueous base fluid, a viscoelastic surfactant gelling agent, two or more types of the following nanoparticles: an alkaline earth metal oxide; an alkaline earth metal hydroxide; a transition metal oxide; or a transition metal hydroxide to form a treatment fluid, and pumping the treatment fluid into the well, wherein the weight ratio of the two or more types of the nanoparticles is selected such that the treatment fluid has an improved fluid efficiency as compared to an otherwise identical reference fluid except for comprising only one type of the nanoparticles selected from an alkaline earth metal oxide; an alkaline earth metal hydroxide; a transition metal oxide; and a transition metal hydroxide.
(FR) L'invention concerne un procédé de traitement d'une formation souterraine pénétrée par un puits, consistant à combiner un fluide de base aqueux, un agent gélifiant tensioactif viscoélastique, deux types, ou plus, de nanoparticules suivantes : un oxyde de métal alcalino-terreux ; un hydroxyde de métal alcalino-terreux ; un oxyde de métal de transition ; ou un hydroxyde de métal de transition pour former un fluide de traitement ; et à pomper le fluide de traitement dans le puits, le rapport pondéral desdits deux types, ou plus, de nanoparticules étant choisi de telle sorte que le fluide de traitement présente une efficacité de fluide améliorée par rapport à un fluide de référence pour le reste identique à l'exception du fait qu'il ne comprenne qu'un seul type de nanoparticules choisies parmi un oxyde de métal alcalino-terreux ; un hydroxyde de métal alcalino-terreux ; un oxyde de métal de transition ; et un hydroxyde de métal de transition.
