Title (EN) PROCESS FOR TREATMENT OF UNDERGROUND RESERVOIRS
(FR) PROCEDE DE TRAITEMENT DE RESERVOIRS SOUTERRAINS
Abstract: front page image
(EN)A process for treating an underground reservoir, which process comprises (a) introducing into the reservoir, separately or together: (i) and ester, and (ii) a compound containing at least one carboxylae functionality, the compound being water-soluble and capable of increasing the rate of hydrolysis of the ester; each of components (i) and (ii) being contained in a treatment fluid in which it is dissolved or dispersed in water; and (b) allowing the ester to hydrolyse to produce an organic acid in an amount effective to acidise the underground reservoir.
(FR)L'invention concerne un procédé de traitement d'un réservoir souterrain. Lequel procédé consiste à : (a) introduire dans le réservoir, séparément ou ensemble : (i) un ester, et (ii) un composé contenant au moins une fonctionnalité carboxylate, ce composé étant soluble dans l'eau et pouvant augmenter le taux d'hydrolyse de l'ester ; chaque composant (i) et (ii) étant contenus dans le fluide de traitement dans lequel il est dissous, ou dispersé dans l'eau ; et (b) permet à l'ester de s'hydrolyser pour produire un acide organique dans une quantité efficace pour acidifier le réservoir souterrain.
