Title (EN) SHEAR TOLERANT AQUEOUS BASED FRACTURING FLUIDS AND METHODS
(FR) FLUIDES DE FRACTURATION À BASE D'EAU TOLÉRANTS AU CISAILLEMENT ET PROCÉDÉS ASSOCIÉS
Abstract: front page image
(EN)A method comprises providing a treatment fluid comprising a gelling agent, an aqueous base fluid, a buffer composition comprising a plurality of salts, and a crosslinking agent; and contacting a subterranean formation with the treatment fluid. The method may be used in subterranean formation having a temperature greater than about 200 °F (about 93°C), and the treatment fluid useful with the method may have a high shear recovery greater than 100%.
(FR)L'invention concerne un procédé qui comprend l'apport d'un fluide de traitement comprenant un agent gélifiant, un fluide à base d'eau, une composition de tampon comprenant une pluralité de sels, et un agent réticulant; et la mise en contact d'une formation souterraine avec le fluide de traitement. Le procédé peut être utilisé dans une formation souterraine ayant une température supérieure à environ 200 °F (environ 93 °C). Le fluide de traitement utile pour le procédé peut avoir une récupération à cisaillement élevé supérieure à 100 %.
