Method for the secondary recovery of petroleum

Abstract

A method for the secondary recovery of petroleum from subterranean formations consists of flooding these formations with aqueous fluids. These aqueous fluids contain one or more saline solutes which are either present before the flooding or which are dissolved from the formation during flooding. These fluids contain, as a thickening agent, a substantially linear, high molecular weight, water-soluble alkenylaromatic polymer which has sulfonic acid or sulfonate groups on the aromatic nuclei. This saline solute and polymer are mutually compatible. (5 claims)
