Title (EN) METHODS FOR TREATING HYDROCARBON-BEARING FORMATIONS HAVING BRINE
(FR) PROCÉDÉS DE TRAITEMENT DE FORMATIONS CONTENANT DES HYDROCARBURES AYANT DE LA SAUMURE
Abstract: front page image
(EN)Method of treating a hydrocarbon-bearing formation having brine and treated hydrocarbon-bearing formations. The method includes contacting a hydrocarbon-bearing formation with a composition comprising solvent and a polymer. The polymer comprises divalent units represented by formula : (formula I); and a plurality of alkyleneoxy groups. In some embodiments, the solvent at least one of solubilizes or displaces the brine in the formation. In some embodiments, the solvent includes at least one of a polyol or polyol ether independently having from 2 to 25 carbon atoms and at least one of water, a monohydroxy alcohol, an ether, or a ketone, wherein the monohydroxy alcohol, the ether, and the ketone each independently have up to 4 carbon atoms. Hydrocarbon-bearing formations and proppants treated with the polymer are also disclosed.
(FR)La présente invention concerne un procédé de traitement d’une formation contenant des hydrocarbures ayant de la saumure et des formations contenant des hydrocarbures traitées. Le procédé consiste à mettre en contact une formation contenant des hydrocarbures avec une composition comprenant un solvant et un polymère. Le polymère comprend des unités divalentes représentées par la formule : (formule I); et une pluralité de groupes alkylèneoxy. Dans certains modes de réalisation, le solvant au moins solubilise ou déplace la saumure dans la formation. Dans certains modes de réalisation, le solvant comprend au moins un polyol ou un éther de polyol ayant indépendamment de 2 à 25 atomes de carbone et au moins de l’eau, un alcool monohydroxy, un éther, ou une cétone, l’alcool monohydroxy, l’éther, et la cétone ayant chacun indépendamment jusqu’à 4 atomes de carbone. L’invention concerne également les formations contenant des hydrocarbures et les agents de soutènement traités avec le polymère.
