Patent ·
OSTI ID:7215952
A polymer flood was proposed for enhanced oil recovery which contained the ionic polysaccharide B-1459 as a thickening agent, and a water-soluble carbonate and/or a water-soluble inorganic polyphosphate to fill substantially all of the adsorption sites within the reservoir. Alternately the sacrificial agent may be injected as a preflush.
