Abstract

soluções poliméricas alcalinas não-iônicas para recuperação de óleo em uma formação subterrânea. é descrito um método para aumentar a recuperação de óleo. o método inclui prover um reservatório de subsuperfície contendo hidrocarbonetos dentro dele e um poço em comunicação fluida com o reservatório de subsuperfície. uma solução para injeção dentro do reservatório é formada misturando-se uma composição com pelo menos uma substância química não-iônica, pelo menos um polímero, e pelo menos um álcali. a substância química não-iônica pode ser alcoxilatos de álcool, tais como alcoóis alquilaril alcóxi ou alcoóis alquil alcóxi. a solução é solução límpida e aquosa estável quando misturada. a solução é injetada através do poço para dentro do reservatório de subsuperfície.
