Recovery of petroleum by flooding with viscous aqueous solutions of acrylic acid--acrylamide-diacetone acrylamide copolymer

Patent ·
OSTI ID:7299577

For similar tertiary oil recoveries by polymer flooding, four times as much by weight of Pusher 500 was required as compared to the acrylic acid-acrylamide-diacetone acrylamide terpolymer. All solutions were made with 3 percent brine. A sand pack model of /sup 1///sub 4/ of a five-spot well pattern was saturated with oil and flooded with brine. The terpolymer solution (2.4 PV slug) recovered 82.5 percent OIP.
