Paul Shu: Programmed gelation of polymers for oil reservoir permeability control. Mobil Oil Corporation, Alexander J McKillop, Michael G Gilman, Stanislaus Aksman, August 19, 1986: US04606407 (49 worldwide citation)

Polymers used for the control of permeability in stratified subterranean formations are gelled in a controlled manner by the use of rapid and delayed gelling agents. The polymer is first gelled lightly by the use of a rapid gelling agent which partly cross-links the polymer to produce a viscous solu ...
