Abstract
The injectivity of micellar dispersions containing wax within the hydrocarbon phase is improved by incorporating into this phase about 0.01-10 percent by weight of a low molecular weight paraffinic hydrocarbon. This invention is especially useful with micellar dispersions obtained from petroleum sulfonates that have been cooled, e.g. to about 40.degree.F., and thereafter heated during injection into a subterranean reservoir for secondary or tertiary oil recovery purposes.
