Non-ionic alkali polymer solutions for enhanced oil recovery in a subterranean formation

A method for enhancing oil recovery from a subsurface reservoir in fluid communication with a wellbore comprising:

• injecting a clear and aqueous stable solution through the wellbore into the reservoir, wherein the solution has a PV×C×10,000 from about 3 to about 15 units where PV represents a dimensionless fraction of pore volumes injected, C represents a mass fraction of the non-ionic chemical, and 10,000 represents an arbitrary conversion factor, and wherein the solution comprises at least one non-ionic chemical, at least one polymer, and at least one alkali.

A method for enhancing oil recovery from a subsurface reservoir in fluid communication with a wellbore comprising:

• injecting a clear and aqueous stable solution through a wellbore into the reservoir, wherein the solution comprises at least one non-ionic chemical, at least one polymer, and at least one alkali, and wherein the solution comprises from about 0.1 to about 0.3 percent by weight non-ionic chemical based on the total weight of the solution.
