Method For Enhancing Oil Recovery With An Inproved Oil Recovery Surfactant

A method for enhancing oil recovery, comprising:

• (a) providing a subsurface reservoir containing hydrocarbons therewithin;
• (b) providing an injection well having an injection wellbore in fluid communication with the subsurface reservoir, and a production well spaced-apart from the injection well a predetermined distance and having a production wellbore in fluid communication with the subsurface reservoir;
• (c) forming a surfactant-polymer solution for injection into the reservoir by mixing a composition with at least one surfactant, at least one polymer, and at least one co-solvent such that the surfactant-polymer solution is clear and aqueous stable;
• (d) injecting the surfactant-polymer solution through the injection wellbore into the reservoir;
• (e) forming a chaser solution having an additional predetermined quantity of the co-solvent for injection into the reservoir;
• (f) injecting the chaser solution through the injection wellbore into the reservoir to increase the flow of hydrocarbons through the reservoir toward the production wellbore while maintaining the clear and aqueous stability of the surfactant-polymer solution;
• and
• (g) receiving the hydrocarbons within the production wellbore.
