The method of recovering petroleum from a subterranean reservoir an acylated polyether polyol, the polyether polyol thereof being derived from the reaction of an alkylene oxide and a member selected from polyols, amines, polyamines and amino alcohols containing from about 2 to about 10 active hydrogens, said acylated polyether polyol being the reaction product of said polyether polyol and a member selected from the class consisting of mono- and polybasic carboxylic acids, acid anhydrides, and iso-, diiso-, and polyisocyanates, said acylated polyether polyol at about 25.degree. C.: (a) being less than about 1% by volume soluble in water and in isooctane; (b) having a solubility parameter in the range of between about 6.9 and about 8.5; and (c) spreading 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 spreading pressure of about 16 dynes per cm.
