Title
(EN) COMPOSITION AND METHOD FOR TREATING A SUBTERRANEAN FORMATION
(FR) COMPOSITION ET PROCEDE PERMETTANT LE TRAITEMENT D'UNE FORMATION SOUTERRAINE
Abstract
(EN)
Aqueous liquid compositions for increasing the permeability of a subterranean formation are disclosed, the compositions being characterized by provision of fluoborate anion (fluoboric acid) and a specified compound or compounds, or mixture thereof, which chelate aluminum ions and aluminum fluoride species. Methods of treating a subterranean formation by injection of the composition(s) into the formation are also described.
(FR)
La présente invention concerne des compositions liquides à base d'eau destinées à accroître la perméabilité d'une formation souterraine, les compositions étant caractérisées en ce qu'elles comportent un anion de fluoborate (l'acide fluoborique) et un composé ou des composés déterminés, ou un mélange de ceux-ci, qui produisent la chélation d'ions aluminium et des espèces de fluorure d'aluminium. L'invention concerne également des procédés de traitement d'une formation souterraine par injection de composition(s) dans la formation.
