ABSTRACT:
A process for the enhanced recovery of oil from a subterranean formation using a polymer-microemulsion complex is disclosed. The polymer is polyethylene oxide or polyvinyl pyrrolidone and interacts with the surfactant of the microemulsion to form a physical association. The resulting complex is characterized by a complexation energy of at least 2 Kcal/mole. Slugs containing the present polymer-microemulsion complexes are stable at high salinity, show reduced destabilization due to surfactant adsorption and retention by the formation, have low interfacial tensions and achieve an early banking, as well as increased displacement of crude oil.
