Abstract
A polymer flood of partially hydrolyzed, highly cross-linked acrylamide in Bartlesville brine (96,000 mg/l TDS) was used to flood the Moore-Holverson-Hill-Aagard unit in Greenwood County, Kansas. The reservoir is a Bartlesville sand (4.3 md permeability, 16.8 percent porosity) and contains 3 cp (at 100/sup 0/F) crude which has a specific gravity of 0.82. Anionic surfactant and metaphosphate were added to the flood to promote water-wetting. The recovery is predicted at about 28 percent OOIP, a profit.
