Abstract
A method of treating a formation containing crude oil is described. The method includes (a) providing a hydrocarbon recovery composition to at least a portion of a formation containing crude oil wherein the composition comprises a high molecular weight internal olefin sulfonate and a viscosity reducing compound; and (b) allowing the composition to interact with hydrocarbons in the crude oil containing formation.

A method of treating a formation containing crude oil comprising:
- (a) providing a hydrocarbon recovery composition to at least a portion of the crude oil containing formation, wherein the composition comprises at least one high molecular weight internal olefin sulfonate and at least one viscosity reducing compound;
- and
- (b) allowing the composition to interact with hydrocarbons in the crude oil containing formation.
A method of reducing the viscosity of a high active matter surfactant comprising contacting a composition comprising at least one high molecular weight internal olefin sulfonate with a viscosity reducing compound to produce a hydrocarbon recovery composition.
A hydrocarbon recovery composition which comprises a high molecular weight internal olefin sulfonate and a viscosity reducing compound.
