Title
(EN) SELF-DIVERTING EMULSIFIED ACID SYSTEMS FOR HIGH TEMPERATURE WELL TREATMENTS AND THEIR USE
(FR) SYSTÈMES ACIDES ÉMULSIFIÉS AUTO-DÉTOURNANTS POUR TRAITEMENT DE PUITS À HAUTE TEMPÉRATURE ET LEUR UTILISATION
Abstract
(EN)
A method of treating a subterranean formation penetrated by a wellbore is carried out by introducing an emulsion composition into the formation through the wellbore wherein the formation has a formation temperature surrounding the wellbore of at least 120°C. The emulsion composition is formed from an aqueous acid component that forms an internal phase of the emulsion, non-aqueous component that forms an external phase of the emulsion, and a surfactant. The emulsion composition also includes an amount of fibers formed from high temperature polymer material. The high temperature polymer material is characterized by the property of not substantially degrading in water at pH<7 at temperatures below 80° C.
(FR)
La présente invention concerne un procédé de traitement d'une formation souterraine dans laquelle est creusé un puits de forage, ledit procédé consistant à introduire une composition en émulsion dans la formation à travers ledit puits de forage, la température de la formation autour du puits de forage étant au moins égale à 120 °C. Ladite composition en émulsion est élaborée à partir d'un composant acide aqueux qui en constitue la phase interne, d'un composant non aqueux qui en constitue la phase externe et d'un tensioactif. La composition en émulsion contient également une certaine quantité de fibres constituées d'un matériau polymère spécial hautes températures. Ledit matériau polymère spécial hautes températures a la propriété de ne pas se dégrader de façon trop importante dans l'eau à un pH < 7 et à une température inférieure à 80 °C.
