Abstract

MÉTODO PARA INTENSIFICAR A RECUPERAÇÃO DO ÓLEO. Um método para intensificar a recuperação do óleo inclui a etapa de fornecer um reservatório de subsuperfície contendo hidrocarbonetos dentro do mesmo. Um furo do poço é fornecido em comunicação de fluido com o reservatório de subsuperfície. Uma solução de tensoativo-polímero é formada para injeção no reservatório. A solução de tensoativo-polímero é formada misturando-se uma composição com pelo menos um tensoativo, pelo menos um polímero, e pelo menos um cosolvente ou cotensoativo tal que a solução de tensoativo-polímero seja estável clara e aquosa. A solução de tensoativo-polímero é injetada através do furo do poço no reservatório. Uma solução de injeção é formada para injeção no reservatório. A solução de injeção tem uma quantidade predeterminada adicional do cosolvente ou cotensoativo. A solução de injeção é injetada através do furo do poço de injeção no reservatório para intensificar a produção de hidrocarbonetos do reservatório enquanto mantendo a estabilidade clara e aquosa da solução de tensoativo-polímero.
