Abstract

A process for the recovery of oil from a permeable underground formation with petroleum content, characterized by the steps comprising: injecting in the formation, through one or more injection wells, a sludge of soluble oil (microemulsions) of minus 1-20 percent of the pore volume of the underground formation to be flooded; the mud has, at its entrance edge, a viscosity at least equal to that of the crude oil in the formation; then inject a fluid into the formation to displace the soluble oil into one or more recovery wells and recover substantial amounts of oil from the recovery wells.
