Mobilization of heavy oil

摘要

A process for increasing mobility of heavy oil includes: disposing a solvating composition comprising a paraffinic solvent and a multifunctional solvent in a heavy oil environment including a heavy oil, the heavy oil comprising asphaltene; contacting the heavy oil with the solvating composition; and stabilizing asphaltene in the heavy oil with the solvating composition to increase mobility of the heavy oil and to form a stabilized heavy oil which includes the heavy oil and solvating composition. A method for making stabilized heavy oil includes separating resin from an oil; combining the resin and a paraffinic solvent to form a solvating composition; disposing the solvating composition in a heavy oil environment which includes heavy oil comprising asphaltene; and contacting the asphaltene with the solvating composition to make stabilized heavy oil, wherein the stabilized heavy oil comprises the solvating composition and heavy oil.

1. A method for increasing mobility of heavy oil, the method comprising:
disposing a solvating composition comprising a paraffinic solvent and a multifunctional solvent in a heavy oil environment including a heavy oil, the heavy oil comprising asphaltene; contacting the heavy oil with the solvating composition; and stabilizing asphaltene in the heavy oil with the solvating composition to increase mobility of the heavy oil and to form a stabilized heavy oil which includes the heavy oil and solvating composition; wherein the multifunctional solvent comprises an ionic liquid and a surfactant different from the ionic liquid, and wherein the ionic liquid comprises one or more of the following cations: pyrazolium; piperidinium; sulfonium; morpholinium; indolium; thiazolium; benzothiazolium; or cyclopropenylium.
