Lee N Morgenthaler, William H Korcz, John L Greak, James R Erickson: Profile control in enhanced oil recovery. Shell Oil Company, Del S Christensen, April 14, 1992: US05103909 (126 worldwide citation)

Oil recovery method using polymer solutions in which highly permeable strata are made significantly less permeable while less permeable strata are not made significantly less permeable. This is accomplished by heating more permeable strata by injection of hot fluids, and then injection of a crosslin ...
