Beschreibung
Zusammenfassung:	Polymer flooding to increase production of formation fluids from a subterranean oil-bearing reservoir of low permeability, utilizing a polymer of a specified average molecular weight with at least 5 percent by weight having an average molecular weight at least 1.2 times greater than this specified average molecular weight is improved by mechanically or physically degrading the polymer solution. This substantially decreases the tendency of the polymer solution to "plug" the formation, while only slightly decreasing its viscosity.
