Title (EN) REVERSIBLE AMINAL GEL COMPOSITIONS, METHODS, AND USE
(FR) COMPOSITIONS DE GEL AMINAL RÉVERSIBLE, PROCÉDÉS, ET UTILISATION
Abstract:
(EN) A well treatment composition for use in a hydrocarbon-bearing reservoir comprising a reversible aminal gel composition is disclosed. The reversible aminal gel composition includes a liquid precursor composition. The liquid precursor composition is operable to remain in a liquid state at about room temperature. The liquid precursor composition comprises an organic amine composition; an aldehyde composition; a polar aprotic organic solvent; and a metal salt composition with valence 3, 4, or 5. The liquid precursor composition transitions from the liquid state to a gel state responsive to an increase in temperature in the hydrocarbon-bearing reservoir. The gel state is stable in the hydrocarbon- bearing reservoir at a temperature similar to a temperature of the hydrocarbon-bearing reservoir, and the gel state is operable to return to the liquid state responsive to a change in the hydrocarbon-bearing reservoir selected from the group consisting of: a decrease in pH in the hydrocarbon-bearing reservoir and an addition of excess metal salt composition in the hydrocarbon-bearing reservoir.
(FR) La présente invention concerne une composition de traitement de puits destinée à l’utilisation dans un réservoir contenant des hydrocarbures comprenant une composition de gel aminal réversible. La composition de gel aminal réversible comprend une composition de précurseur liquide. La composition de précurseur liquide peut fonctionner pour rester à l’état liquide à environ la température ambiante. La composition de précurseur liquide comprend une composition d’amine organique ; une composition d’aldéhyde ; un solvant organique aprotique polaire ; et une composition de sel métallique avec une valence de 3, 4, ou 5. La composition de précurseur liquide effectue une transition de l’état liquide à un état de gel réagissant à une augmentation de la température dans le réservoir contenant des hydrocarbures. L’état de gel est stable dans le réservoir contenant des hydrocarbures à une température semblable à une température du réservoir contenant des hydrocarbures, et l’état de gel peut fonctionner pour revenir à l’état liquide réagissant à un changement dans le réservoir contenant des hydrocarbures sélectionné dans le groupe constitué de : une baisse du pH dans le réservoir contenant des hydrocarbures et une addition de composition de sel métallique en excès dans le réservoir contenant des hydrocarbures.
