Abstract

The invention deals with the enhanced recovery of oil and natural gas from reservoir formations by microemulsion injection. Formations surrounding oil wells, gas wells, injection wells and similar bore holes are treated by the injection of a microemulsion containing an acid solution. The main surfactant of the microemulsion is characterized by having at least two hydrophobic nitrogen substituents. 1 tab.
