ABSTRACT:
A method of improving production of heavy crude oil from a well by mixing a first solution of water soluble surfactant and water, and preferably forming a mixture of the first solution and an oil solvent, and pumping the mixture into the well to mix with the heavy crude oil to be produced. A desirable surfactant is a water soluble ethoxylated nonylphenol and a desirable oil solvent is kerosene distillate.
