Blair, C M

A method is described for recovering petroleum from a subterranean reservoir using a polyepoxide condensates of at least one of the following: (A) a polyalkylene oxide adduct of a fusible, water-insoluble organic aromatic hydrocarbon solvent-soluble synthetic resin, wherein said resin has from between about 4 to about 15 phenolic groups and is an alkyl or cycloaliphatic substituted phenol-aldehyde condensate and (B) a polyether polyol including polyether amino polyols. These polyepoxide condensates at about 25/sup 0/ C should: (I) be less than about 1% by volume soluble in water and in isooctane; (II) have a solubility parameter in the range of between about 6.9 and about 8.5; and (III) spread at the interface between distilled water and refined mineral oil to form a film having a thickness no greater than about 20 angstroms at a film pressure of about 16 dynes per cm.
